Although technically still considered summer until the equinox, the month of September ushers in the beginning of fall, the season most associated with change and impermanence, with encroaching darkness, with death and transition and the melancholy appreciation of the last burst of colour before the inevitable bleakness of winter. I can’t help but be reminded that this is the season of endings every time I go outside: the robins are gone from the neighbourhood, the songbirds in the woods have stopped singing, trees are changing colour, and the asters and goldenrods have replaced all the other wildflowers along roadsides and in conservation areas. In the dragonfly world, it is the season of the meadowhawk, the glider, and the darner, as these types of dragonflies are by far the most numerous. The goal now is to search out any others that may still be flying, and see how long into the season they last. Part of the reason is purely scientific – to get a better grasp of the flight seasons of local odonates. However, another part of the reason is purely emotional – I never know if a sighting will be the last of the year, and hope to put off the final goodbyes as long as possible.
After I returned from my visit to southern Ontario I still had bugs on the brain, specifically odonates. Now that September has arrived the days will be getting shorter and the nights cooler, which spells the end of the season for a number of different species. It is, however, prime time for darners, and I still had yet to find a Lake Darner or Green-striped Darner this year. I also haven’t seen any Saffron-winged Meadowhawks either, another species that peaks in August and early September, despite searching known locations at the Eagleson storm water ponds. While I knew that bird migration was heating up, my brain hasn’t yet made the switch from odes to birds. I am having trouble getting up early enough to get out for my regular birding walks before work, and I won’t even consider putting my net away while the weather is still nice – I want to wring every last sunny moment looking for dragonflies and damselflies before taking the mandatory six-month winter hiatus. This has never happened to me before, and while I still am using eBird to keep track of what I see, most of my checklists are incidental ones noting only a few species that caught my attention while out later in the day dragonfly-hunting.
Although I could have spent most of my time in Chatham-Kent at Peers Wetland, we visited a few other places in my quest to find odonates around Wallaceburg. After a productive morning at Peer’s Wetland on August 31st, we went home for lunch, then took a walk at Crothers Conservation Area only a few blocks from my mom’s house in the north end of Wallaceburg. This little slice of green space runs alongside Running Creek, a small muddy stream which flows into the North Sydenham River. Although this small conservation area consists mostly of neatly manicured lawn, and more rightly ought to be called a park than a conservation area, the riverbank has some natural growth of riparian shrubs and cattails that prevent it from looking too obviously landscaped. Wild green space is scant in the southwestern corner of the province – a bird’s eye view shows it to be entirely dominated by the patchwork of farms vital to the province’s agricultural industry. The few remaining patches of forest, wetlands, and untamed thickets along the riverine corridors are precious; it seems that in this part of the province, every square inch has been assessed and tallied with almost all of it given over to human management, whether for production, recreation, residential, or commercial purposes.
My mother lives in Wallaceburg in Chatham-Kent, which is about a 7.5 hour drive from Ottawa, or a full day train adventure with a transfer in Toronto (my advice for anyone travelling economy on Via: take your own sandwiches and snacks, as the menu was somewhat unpalatable…and chocolate bars/chips alone were $3.00). Being so far south she gets a variety of birds, bugs and plants that we do not get here in eastern Ontario, so I’ve been meaning to visit in the summer when I might see some new southern butterflies and dragonflies for my life list. I took an extra two days off at the end of August so I could spend the Labour Day long weekend with her, though two of the days were lost to travel. As my mother and her husband both enjoyed birds and nature, I knew they’d be interested in taking a few nature walks with me, even if the idea of looking for dragonflies didn’t exactly fill them with delight.
When I first heard about the Odolympics – a special bioblitz hosted by the Dragonfly Society of the Americas, Sociedad de Odonatología Latinoamericana, and Odonata Central in order to record as many odonata species from as many places in the Western Hemisphere as possible – I knew I had to participate. This specialized bioblitz is only two years old, and there are usually two Odolympics each year: one falling during the North American summer, and one falling during the South American summer in order generate a snapshot of odonate distribution throughout both hemispheres.
Dragonflies and damselflies, collectively known as odonates, are valuable indicators of a wetland’s environmental health and biodiversity. Simply put, the more odonates that use a wetland for breeding and feeding purposes, the healthier the ecosystem. Naturalists were encouraged to submit their observations during the bioblitz via one of two platforms: iNaturalist, or Odonata Central. While I love iNaturalist and have been using it for a few years now to record my non-avian observations, I began submitting my observations to Odonata Central last year when it developed a checklist-based phone app similar to eBird. iNaturalist also has a phone-based app for submitting observations, but it is intended to be used in conjunction with the phone’s camera which I only use as a backup camera when my Nikon Coolpix’s battery decides to take a nap. Although I love the ease of searching for data in iNaturalist’s projects, I chose to record my Odolympic observations in Odonata Central as it allowed me to include observations of species for which I am usually unable to get a photo (yes, I’m looking at you, Prince Baskettail and Wandering Glider!)
July is usually the start of the best three months of ode-hunting at Andrew Haydon Park. Although I often visit the park in the spring and fall for birds, my time here in the summer is devoted to dragonflies. This park is reliable for Halloween Pennants, Blue Dashers, Eastern Pondhawks, Common Green Darners, Prince Baskettails, and the usual King Skimmers, and I’ve had Cobra Clubtail and Elusive Clubtail here as well. I visited on July 29th with the hope of seeing another Cobra Clubtail, as it was on July 21, 2019 that I saw one fly into a tree on a windy day, eating what looked to be a male Orange Bluet. Though I’ve looked for both species here in July in subsequent years, I only had luck with one female Orange Bluet on July 24, 2021.
It was only six weeks ago that I last added a new species to the Eagleson storm water ponds ode list, the River Jewelwing that mysteriously showed up for one day back on June 10, 2023. I wasn’t expecting to find another new species so soon, but that is exactly what happened when I went for a walk there this afternoon. My goal was to look for the diminutive Eastern Amberwings, a species that I would have looked for earlier in the month had I not been in Nova Scotia. This colony first showed up in 2017 and its numbers have been increasing in the southern ponds over the last six years. I was happy to find four males perching on the lily pads on my visit; it appears they are still thriving here.
Eastern Amberwing
I saw Orange Bluets here for the first time this year on July 3, 2023, and I was hoping to find a few close enough to the shore to get a good photo. This is the second season that I’ve confirmed their presence here, and I was disappointed not to find any on this visit.
I saw Blue Dashers here for the first time this year on July 7, 2023; this is also only the second year that I’ve seen them here, and I counted at least eight of them around the two southern-most ponds. They are so beautiful and colourful when fresh – I can’t imagine ever becoming so used to them that I don’t want to stop and admire them, especially when they are sitting on a such a lovely perch.
Blue Dasher
I saw a male and female Common Whitetail flying over the pond together; the female was ovipositing. A White-faced Meadowhawk and a Band-winged Meadowhawk were nice to see, though the Band-winged Meadowhawk didn’t stick around long enough for photos. I’ve been keeping an eye out for Saffron-winged Meadowhawks, a species that was common here in 2020 but has been diminishing in numbers ever since – I only found two in 2021 and one in 2022. I didn’t see any on this walk, making me wonder if the population has died out. Its season lasts until September, so it is not too late to keep looking for this species.
A Slender Spreadwing was the only other odonate of interest, other than the Eastern Forktails that are usually too numerous to count.
I finished my walk with a loop around the Hope Side pond, stopping at the bridge where I took a moment to scan the water toward the overpass. I’ve seen muskrats swimming and dragonflies flitting among the vegetation here, and almost immediately something small and black fluttering in the tunnel formed by the cattails toward the bridge. When I got my binoculars on it I saw a male Ebony Jewelwing sitting in the sun!
Ebony Jewelwing
Ebony Jewelwings are usually found at woodland streams, preferring those with rapids although they may be found at shaded, slow-moving streams as well. The area it was inhabiting at the Eagleson ponds is no more than a shallow channel that drains water from the ponds into a narrow waterway running alongside a patch-work of fields before entering the Jock River at Terry Carisse Park. But since a River Jewelwing has already found its way up here perhaps I shouldn’t be surprised that this Ebony Jewelwing had followed. This is ode species #36 for the ponds – a terrific number for such a small area and limited habitat.
The weather played a big part in our trip this year. Rainclouds blew in and blew out all week long, bringing rain on most of the days we were there. Fortunately the sun came out long enough to get in a few hikes at the various waterfalls and for me to take some long walks while Doran was out with the car. I spent quite a few hours looking for odonates and other critters around the ponds and the Annapolis Rail Trail, mostly in the afternoons when the sky cleared up. Although they are maybe half as long as the Eagleson storm water ponds by my house and much less diverse in terms of wildlife species, I still managed to find an interesting variety of creatures.
The afternoon after our waterfall search was particularly productive. I found my first Band-winged Meadowhawk and Familiar Bluet of the trip, which are also my first observations in iNaturalist for Nova Scotia for these species.
Doran and I visited Nova Scotia again in mid-July, now one of my favourite times to visit after seeing so many dragonfly species on our last trip. This time we rented an Airbnb in Middleton – the basement suite of a house right on the Annapolis River. Although the vegetation along the river was much too thick to get close to the water, there were a few well-trampled trails leading down to the water’s edge. In addition, our location was close to both Bridge Street (Highway 10), with Riverside Park on the opposite bank, and the South Shore Annapolis Trail which has its own bridge across the water and runs behind Riverside Park and the Middleton sewage lagoons. We got settled into the apartment, and the following day that Doran and I went exploring. My fiancé had recently become interested in searching out local waterfalls, and as a number of clubtail species can be found on fast-flowing rocky rivers, I was more than keen to accompany him.
Chris Traynor and I chat about dragonflies and damselflies a lot. We both also like to pour over old dragonfly reports, iNaturalist records, and Google maps looking for suitable habitat for this species or that, as well as interesting places to go dragon-hunting in general. It was Chris who, when searching for places to see Clamp-tipped Emerald, thought that Taylor Lake in the northwestern part of Gatineau Park might be worth a visit. There are two iNat records from the area from 2015, as well as one Brush-tipped Emerald record from a few kilometers away. The map shows a variety of ode-worthy wetlands including streams, ponds, seeps and marshes, and an exploratory hike of about 5 kilometers in the fall cemented his impressions and desire to return there during prime dragonfly season. It was also almost completely unexplored for odonates, which made it quite enticing in my eyes, and close to a spot where Chris Lewis and Bob Bracken had discovered a stream with mature Eastern Least Clubtails and other clubtails several years ago. Good Somatochlora spots in the Ottawa-Gatineau region are uncommon, and we both thought would be fantastic to discover one up in Gatineau Park. I emailed Chris Lewis about Chris’s idea to check on the trails around Taylor Lake and revisit some of her and Bob’s footsteps in Gatineau Park, and the three of us made plans to visit its northern reaches on July 8th.
I’ve been studying the map on iNaturalist over the past few weeks, looking for new parts of Marlborough Forest to explore. In particular, I’ve been looking for ways to access it from the south, where there are very few trails or points of entry….and very few odonate records. Paden Road runs along the southern boundary, while Malakoff Road winds along its eastern boundary. There is one formal trail on Paden Road, and there are other roads that enter the forest and come to dead ends with what look like trails extending beyond them. I found four places that looked intriguing: one such trail extending beyond Mulholland Road at Harnett Road; a place further south on Harnett Road where it cuts through a large wetland; another extension beyond Weedmark Road off of Paden Road; and the Paden Road trail itself. I planned a day outing in June to see if these places were as fantastic for odes as they looked on the map. If I had time, I also wanted to explore Heaphy Road on the western boundary, which runs through another big wetland. I scheduled this project for the second Sunday in June and was looking forward to it; however, when I woke up on June 11th and saw that the forecast called for increasing cloudiness with a low chance of rain later the afternoon I wasn’t sure if I would see many bugs. However, I didn’t want to put it off as it was already almost the middle of June and soon many species would be done for the year.
Spiketails are large, brightly coloured dragonflies that inhabit small or mid-sized streams, usually with a good current in forested areas. There are three species present in eastern Ontario, all with dark brown or black bodies, green eyes, and bold yellow patterns along the abdomen that may cause them to be confused with clubtails in flight. Each species has a dark thorax with two vivid yellow stripes on the side and two smaller yellow dashes on the top. It is the pattern on the top of the abdomen that distinguishes them: the Arrowhead Spiketail has a single line of yellow arrows pointing toward two round spots at the tip; the Twin-spotted Spiketail has two lines of yellow spots with straight tops and rounded bottoms running down the abdomen, set close together; and the Delta-spotted Spiketail has two lines of widely-separated spots running down the abdomen, each pointed and distinctly triangular in shape. Because of their habitat requirements, they are considered local and uncommon, and in Ottawa the Arrowhead Spiketail is considered the rarest of the three.
I wasn’t expecting to find a new species for the Eagleson storm water ponds when I went there this morning, let alone two; my main goal was to look for some Rainbow Bluets in the vegetation around the southern-most pond. My walk started normally enough, with the usual odonates perching in the vegetation: Taiga Bluets, Eastern Forktails, Sedge Sprites, and even a Fragile Forktail. I headed out onto the small spit of land where I used to see Saffron-winged Meadowhawks and Eastern Amberwings perching over the water before the sparse planting of cattails became a solid, impenetrable wall of vegetation. There was one dragonfly here, and I caught a glimpse of the black and white colours as it landed on the ground ahead of me. It was Chalk-fronted Corporal, and at first I thought nothing of it as I snapped a few photos for my iNaturalist project. After all, these dragons were not only common, but also abundant where they happened to emerge. It took me a moment to realize that although I see them quite regularly at Sarsaparilla Trail and in Marlborough Forest, I had never seen one here at the ponds before. It was a new species for my project!
Chalk-fronted Corporal (Ladona julia)
I only saw one as I made my way around the southern-most pond, but then I didn’t have time to check any of the others. Would it be a one-time visitor, like the Racket-tailed Emerald of 2022 or the Violet Dancer of 2020? Or would more follow? I’d seen a noticeable decline in skimmer numbers over the last year or two, so new additions were definitely welcome. There are fewer Common Whitetails, Twelve-spotted Skimmers, Widow Skimmers, Eastern Pondhawks and Dot-tailed Whitefaces around the edges of the ponds than there used to be. While none of these had ever been truly abundant, I would usually see a few on most visits in appropriate weather. I suspect the large number of fish – particularly carp, which feed by disturbing the wetland floor and stirring up sediment containing dragonfly larvae – and growing number of frogs and toads are likely responsible for this decline, but have no evidence to support this theory.
I found some Rainbow Bluets in the vegetation right where I expected them – they seem to prefer the western side of the southern pond – and was reassured when I saw a Common Whitetail a little later, flying over the small J-shaped pond next to the rock bridge before landing on a bare patch of ground sloping down to the water. I was making my way around the pond back to my car, looking for pondhawks basking on the rocks when something black fluttered in the vegetation below me. When I identified it as a male River Jewelwing I was astonished, as this was a species I never expected to find here at the ponds.
River Jewelwing (Calopteryx aequabilis)
River Jewelwings live along medium-sized streams and small rivers with a slow to moderate current and plenty of submergent vegetation. They prefer more open waterways with more sunlight than Ebony Jewelwings, though the two species are often found together along wooded streams. The closest places I’ve seen River Jewelwings are the stream at the back of Jack Pine Trail in Stony Swamp (which I call Spiketail Creek), and Stillwater Creek at Corkstown Road just east of Moodie Drive. The former was a one-time visitor, while the latter was seen during an exploratory excursion in 2015 with Chris Traynor after I saw one away from the water across the road in 2011.
There is a small channel of water that runs south from the Eagleson storm water pond system through farmland before reaching the Jock River at Terry Carisse Park. It has enough of a current to keep it open during mild winters, and I suppose it is just as likely that the River Jewelwing flew up the channel as it is that it flew or was blown south from Stillwater Creek. It’s a mystery as to where it came from and where it was going when it found the ponds, and I expect this to be a one-time visit rather than the harbinger of a new population of River Jewelwings at the ponds.
As I was photographing the jewelwing I saw two Common Green Darners fly by in tandem. This species is common at the ponds, and I usually see one or two patrolling the shoreline every visit in the first couple of months of the season. The pair stopped so the female could lay her eggs, inserting the tip of her abdomen into the water while still connected to the male:
Common Green Darners (Anax junius)
It is always fun adding new species to my project, especially if they become permanent residents: the larger the number of residents, the healthier the ecosystem. Dragonflies and damselflies in particular are good bioindicators of water quality and the health of a wetland, as they require clean water in which to grow as larvae and survive to adulthood. Given that the purpose of the storm water ponds is to collect poor-quality runoff from the surface of the city streets, which often contains road salt, vehicle fluids, bacteria, fertilizers, pesticides and other pollutants, I had my doubts whether these ponds could support a vibrant population of dragonflies. However, with recent additions such as the Orange Bluet, Eastern Amberwing and Band-winged Meadowhawks, whose populations seem to be stable, it seems that the water quality is in fact high enough to allow these species to thrive.
My informal list stands at 35 species as of June 2023, which is the same number as the species recorded on the iNaturalist project, though with two differences: I don’t count the single record of Hagen’s Bluet which shows up there, as the photos do not show sufficient detail for me to identify it; and I do count Prince Baskettail which is not in iNaturalist, as I have seen many but have not been able to photograph or catch one. I don’t count the Northern/Sweetflag Spreadwings which I’ve seen but haven’t been able to catch, either, since identification requires a close view of the male’s claspers….all goals for future visits!
So what species will turn up here next? I’m thinking Powdered Dancer or Halloween Pennant are most likely, but with dragons and damsels one just never knows. As my mentor says, odes – just like birds! – have wings and can turn up anywhere!
Family Corduliidae (the emeralds) is one of my favourite dragonfly families. My love for these green-eyed beauties grew when I started seeing a large number of Williamson’s Emeralds (Somatochlora williamsoni) in Stony Swamp in the summer of 2014; one particular day at the end of June stands out in my memory because I found a total of five emerald species at Jack Pine Trail in one visit (Common Baskettail, Prince Baskettail, Racket-tailed Emerald, Brush-tipped Emerald and Williamson’s Emerald). It was around that time that I realized that I didn’t have to wander too far from home to see such a fantastic variety of wildlife – Stony Swamp in particular is amazing, with the Eagleson storm water ponds close behind. I saw two Williamson’s Emeralds in Stony Swamp in 2018, then none in any subsequent years. The Brush-tipped Emerald population was still present as of last year, with one iNaturalist record (not mine) from Old Quarry Trail on July 1, 2022.
Sunny skies, a predicted high of 20°C, and a day off from work on the last Friday in May meant plans to visit Marlborough Forest for the first time this season with my mentor, Chris L. I had convinced her to come with me to trail E4 north of Roger Stevens Drive, home of the Ocellated Emerald, Ashy Clubtail, and Twin-spotted Spiketail – though it was too early for any of those to be flying yet. No less exciting were the possibilities for the early spring dragons that should be on the wing by now: Harlequin Darner, American Emerald, Ebony Boghaunter, and maybe a Springtime Darner or Stream Cruiser. We were sure to see plenty of whitefaces and other skimmers, some baskettails and a Dusky Clubtail or two, and some gossamer-winged butterflies to keep things interesting…the great thing about Marlborough Forest is that it is home to an amazing number of species not easily found in the city, so anything is possible!
