The morning of July 18th was warm and cloudless, so we resumed our search for rushing creeks, waterfalls, and odes. I had noticed one spot on Google maps that wasn’t too far from us – Slokum Brook Falls, just north of the Trans-Canada Highway. Photos showed a nice little brook with a steep waterfall in the middle of the woods, and reviews on Alltrails.com indicated that it was a bit difficult to find, as it is very overgrown at the beginning. It is said to be the highest falls on the North Mountain that drains into the valley, though there is really only water here during the spring runoff. We drove down Lily Lake Road, slowing down once we got past the lake itself. I peered into the dense foliage along the road, and found only two spots that looked like trails entering the woods, though both had “private property” signs at the entrance. Once the forest opened up we realized we must have gone past it, and decided to turn around at the end of the road, which elbowed north onto Douglas Road as the woods gave way to farm fields.
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!
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!
Last year a particular OFNC outing caught my eye: a bioblitz to be held at the Morris Island Conservation Area on September 10th. Morris Island is a fantastic place for a bioblitz; the woodlands and wetlands of this 47-hectare site are home to a number of fascinating wildlife species, including several ode species not regularly found in my area of the city. I had never gone ode-hunting in September there before, as September is past the peak of ode season, with fewer species flying than in June or July. Still, it was a good chance to observe what was still flying there, and maybe find an unusual darner species or two. I attended with Chris T. and Chris L. and we photographed seven species for inclusion on the Morris Island Bioinventory Project on iNaturalist: Skimming Bluet, Eastern Forktail, Fragile Forktail, Powdered Dancer, Halloween Pennant, Autumn Meadowhawk, and White-faced Meadowhawk. So much for finding any cool darners!
Dragonfly season (usually from mid-May to early November) is my favourite time of year. If the Victoria Day long weekend in May is warm and sunny, I’ll be out looking for the first emerging baskettails, whitefaces, and emeralds at some of my favourite spots in Stony Swamp or Mud Lake. I don’t usually see dragonflies before then since I’m busy working during the week, and weekend weather earlier in the month is not always conducive to dragon-hunting. Any dragonflies that I do see prior to the middle of the month are usually Common Green Darners that migrate here from further south. There was one year I found a migrant Common Green Darner at Hurdman Park in mid-April (April 19, 2011), but that is the exception rather than the rule. So when I visited a small pond along on NCC Trail 24 in Stony Swamp I wasn’t expecting to see anything other than the Wood Frogs I could hear calling from around the edges, and certainly not the tiny Spring Peepers with calls so loud you would swear they were right in front of you.
Darner (genus Aeshna) season typically begins in July in the Ottawa-Gatineau region. The two most common mosaic darners, Lance-tipped and Canada, emerge early in the month, along with the slightly less common Shadow Darner. These three species are the most widespread members of this group, and if you see a mosaic darner flying along a forest trail or in an open clearing in the greenbelt it is most likely to be one of these. Lake Darner, Variable Darner, and Black-tipped Darner are considered “uncommon” in the Ottawa-Gatineau region, with the first being a localized species and the latter two species considered to be widespread. I suspect they may be easier to find on the Quebec side of the region, as there are more lakes and suitable bodies of water in Gatineau Park, and Black-tipped Darner has been relatively easy to find there. Finally, the Mottled Darner and Green-striped Darner are both considered “very rare”, with only a handful of records of each. I’ve been lucky to see a few Green-striped Darners in Stony Swamp in recent years, with one individual at Bruce Pit in September 2019 and two individuals at the Beaver Trail in September 2021. I’ve never seen a Mottled Darner, and hope to catch up with this species one day.
By mid-August most dragonfly species are on the wane. A few families are still quite abundant, particularly the darners and meadowhawks, while small numbers of other skimmers and a few clubtails often linger into September. Forktails, bluets, and some spreadwings are also still common in the appropriate habitats in August and September. This makes it worth going out to good dragonfly habitats such as large rivers, lakes and marshes to see a decent variety of species.
Large dragonflies this time of year are particularly interesting; while Common Green Darners are the most frequently encountered large dragonflies of late summer, you might come across a Black-shouldered Spinyleg basking on the rocks along the river, a Wandering Glider zipping over a meadow, a Twelve-spotted Skimmer flying above a pond, or a group of mosaic darners swarming through the air late in the afternoon. The mosaic darners are a particular favourite of mine; they are large brownish-black dragonflies with mottled spots of blue, green or yellow depending on the sex. While they spend most of their time flying through the air hunting for small insects, I often come across them perching vertically on thick stalks of vegetation below knee-height in open grassy areas early in the morning. We have several different species in Ottawa, and trying to find something other than the ubiquitous Canada and Lance-tipped Darners is a fun exercise.
Mud Lake and Andrew Haydon Park are usually excellent places to find different species of dragons and damsels throughout the summer months. In both 2015 and 2019 I had a good number of species at Andrew Haydon Park in late July, and an OFNC dragonfly outing at Mud Lake on July 21, 2013 also netted some fantastic species. I was hoping for some similar luck on an ode-hunting trip on July 24th, but this time I found fewer species and fewer individuals overall. I am not sure why there seem to be so few dragonflies around good pond habitat these past two years (such as the Eagleson ponds), but the trend is concerning.
My first stop was the shoreline at Mud Lake where I hoped to find some large river clubtails perching on the rocks in the channel behind the filtration plant. When I arrived I was happy to find two dragonflies perching on the rocks right away, and managed only to photograph one before a couple of people came along and scared them both – while I’m certain one of them was a clubtail, the one I photographed turned out o be an Eastern Pondhawk. The clubtail did not return, although I saw a couple flying out over the water several times on my visit.
My first real dragonfly outing of the year occurred on May 24, 2021, and as usual, took place at Roger’s Pond in Marlborough Forest. I invited a few friends to join me now that outdoor gatherings can include up to 5 people, and fellow OFNC members Derek and Gerald decided to join me. It was a warm, sunny day, and I hoped to find the usual common skimmers and clubtails, as well as a few uncommon species that I’d seen previously at Marlborough Forest such as the elusive Ebony Boghaunter and Harlequin Darner. I’ve already seen one boghaunter this season, but it’s been a few years since I’ve seen a Harlequin Darner, and the Cedar Grove Nature Trail has been a repeat site for this ode.
We met at 9:30 am, just early enough to get some birding in while waiting for the sun to rise higher in the sky. We had the usual Nashville Warblers, Black-throated Green Warblers, Great Crested Flycatchers, White-throated Sparrows, Veeries, and Yellow-bellied Sapsuckers on the walk in. At the pond itself we had Eastern Kingbirds, a Pied-billed Grebe, Common Yellowthroats and four Ring-necked Ducks. Many dragonflies were already flying along the open trail through the cedar forest, including a few teneral whitefaces and emeralds.
Gatineau Park is a special place for dragonflies – many species of the National Capital Region can be found there that aren’t found on the Ontario side of the Ottawa River, while others seem to be much more common there than in Ottawa. Chris Traynor has been exploring the park quite a bit these past couple of years, searching for dragonflies that breed in the quiet lakes, sluggish streams, and fast-flowing creeks of the Gatineau Hills. Not surprisingly, he has found a good number of species that have not been reported in Ottawa, such as Eastern Least Clubtail, Mustached Clubtail, Beaverpond and Harpoon Clubtails, and even a couple of snaketails. Many of these species prefer clear, swift-moving streams with rocky bottoms, which might be the reason for their absence in Ottawa; the Ontario side of the National Capital Region is relatively flat, with more marshes and slow-moving, mucky streams winding through suburbs and forest rather than down the foothills and escarpments which form the Canadian Shield. One of Chris’s best finds was a portion of Meech Creek where Zebra Clubtails and Fawn Darners are quite common, with the occasional Dragonhunter and Violet Dancer. I accompanied him twice to this magical spot, once during the August long weekend last year, and once again this year. As I never did get around to posting those photos last year (remember I mentioned I’d fallen behind?), I will incorporate both sets of photos in this post.
By the time September rolls around, most odonate species are done for the year in the Ottawa region – gone are the Aurora Damsels and Elegant Spreawings, the Spiny Baskettails and Ebony Boghaunters, the Arrowhead Spiketails and Horned Clubtails, the Chalk-fronted Corporals and Four-spotted Skimmers. This is the time of year when the number of meadowhawks and darners begin to peak, and southern species such as Spot-winged and Wandering Gliders may blow into our region with the warm south winds. A few bluet and spreadwing species may persist, as well as the common and widespread Eastern Forktail, though each day sees fewer and fewer individuals. This is a summary of species I saw and photographed around Ottawa during September 2019 – due to my trip to Edmonton and some cool, cloudy weekends, I didn’t visit as many places as I had hoped and missed a few common species.
On September 18th I flew to Edmonton to visit my sister for a few days. Alberta is not a new province for me; my family had lived on an acreage outside of Ardrossan, which is east of Edmonton and Sherwood Park, for seven years from 1989 to 1996. As I was just teenager at the time, enduring all the drama and angst of high school, I had had no interest in nature back then – which is really too bad, as we’d lived on a small lot with a forest behind our house and a slough (a vegetated pond) across the road. When my parents and I moved back in 1996 – they to southern Ontario, via Tweed, and me and my fiancé to Ottawa – my sister remained behind, although it wasn’t until 2012 when I returned to attend her wedding.
My sister has since divorced and now lives in the north part of Edmonton, in a brand new development called Crystallina Nera. It is so new that there are no trees or gardens yet, several houses have not yet put down any sod, and houses are still being built nearby. This developments boasts a 4.8 hectare urban forest and a naturalized storm water pond, both of which I spent a lot of time exploring.
August isn’t my favourite month to go dragon-hunting; in our region, a number of species have already vanished for the year, including several of my favourite clubtails and emeralds, cruisers and spiketails. August, then, is a season of skimmers and darners, and as such, places like the Eagleson storm water ponds are good places to go dragon-hunting, as these are the most common families of dragonflies that breed here (of the other families mentioned above, only the emeralds are present, and only members of the genus Epitheca, the baskettails). I’ve spent much of my free time this month at the storm water ponds, not just looking for butterflies, but also for new species of odes. It was only two years ago that I discovered new populations of Eastern Amberwings and Saffron-winged Meadowhawks breeding here, and as a number of common species are still scarce or still missing, it is worth checking to see if any have made their way here yet. For a habitat that is quite similar to that of Mud Lake or the ponds at Andrew Haydon Park, it is curious to me that there are no Powdered Dancers, no Horned or Lancet Clubtails, no Halloween or Calico Pennants, no Blue Dashers, and very few Widow Skimmers, Dot-tailed Whitefaces, Eastern Pondhawks, and Common Whitetails. Even spreadwings and dragonflies as abundant as the Autumn Meadowhawk are difficult to find. This is why it is such a surprise that uncommon species such as Eastern Amberwing and Saffron-winged Meadowhawk have become quite common here in late summer.
In late August I took my usual trip to southern Ontario to see my Dad. As usual, we spent a few days at his trailer in the Pinehurst Lake Conservation Area. The birding was fine, although this time there were no flocks of migrants moving through; instead the birds still seemed busy with raising and feeding their young, even this late in the summer. For example, I saw a Red-eyed Vireo feeding a Brown-headed Cowbird, a young Indigo Bunting following its parent around, and a House Wren carrying food. We didn’t see the Broad-winged Hawk family this year either, which was disappointing. However, the insects were fascinating, and I found a lot to photograph.
The Equinox fell on Thursday, and by then the winds were blowing down from the north, putting an abrupt end to summer. Although I quite love the crisp, cool days of fall, I hate the cold early mornings which require hats and gloves to stay warm. This morning I headed out to Jack Pine Trail, leaving at 8:15 – the sun is visibly lower in the sky now – and I wished I had brought gloves as my hands were so cold. A Blue Jay and some chickadees were feeding on seeds left on the ground in the parking lot, and it seemed strange not to hear any Red-eyed Vireos or Eastern Wood-pewees singing.
