I am a lover of nature whose primary interests are birds, butterflies, and dragonflies. While I enjoy photographing them, my main interest is in observing and learning about the species I see through my lens. For those of you who are interested in seeing the best of my nature photos, please feel free to check out my gallery on Pbase.
Bruce Pit is under-valued as a great spot to see a variety of insects at the peak of summer. Though I’ve spent a lot of time looking for dragonflies there, it can be quite good for tiger beetles and butterflies as well, including Wild Indigo Duskywing, Gray Comma, Painted Lady, Compton Tortoiseshell, and migrating Monarchs. A visit anytime during the summer can usually turn up a few interesting species, and this year I started visiting on June 17th this year, hoping to find a few different insect species for my life list.
I did not get out to Marlborough Forest as often as I would have liked this past summer; ongoing medical issues early in the season left me feeling too tired and too sore for the long five-hour outings I enjoyed so much last year. On June 2nd I visited the E6 trail with Rick Collins to look for the Sedge Wrens breeding there. We heard one without too much difficulty, though we weren’t able to spot it. Our other highlight was a female Ruffed Grouse on the trail trying to lure us away from its chicks (none seen) by giving distress calls. It was a gray, drizzly day so I didn’t see any insects worth photographing. Indeed, I didn’t take my camera out of my bag at all.
The weather was much better on June 19th, so Chris Traynor and I went to trail E4 to look for Twin-spotted Spiketails and some different emerald species for his life list. I was also eager to show him the pool below the culvert as this was where I’d seen my one and only Ocellated Emerald hanging out in 2020. It was a bit windy, but the sun was shining and the weather was warm, and the breeze made the usual biting insects less of a distraction.
On May 14th I wrote about a mass emergence of Spiny Baskettails at Mud Lake but didn’t explain much about how I identified them except to say my identification was based on the shape of the male claspers. Emerging dragonflies are pale and translucent, showing little to no colour of the mature adults they will become, but fortunately identification of the three small baskettail species in Ottawa does not depend the pattern of colours on its body (a fourth species, the Prince Baskettail, is much larger and has distinctive black spots at the base, tip and center of its wings). This post provides more detail about how to distinguish between the Common Baskettail, the Spiny Baskettail, and the Beaverpond Baskettail, three similar-looking species of the emerald family. While they are most likely to be found patrolling sunny woodland openings or grassy spaces next to water, they often perch on tree branches and plant stems at an angle, allowing good views or photographs.
By May 14th Ottawa had seen a string of six days with temperatures above 20°C, with the last three above 30°C. The warmth signaled the beginning of ode season, with my first dragonflies of the season – both Common Green Darners – seen at the Richmond Conservation Area (May 10) and Sarsaparilla Trail (May 11, 2022). Common Green Darners are migrants, however, arriving on the warm winds flowing from further south. The true ode season begins once it is warm enough for local dragonflies and damselflies to emerge from the rivers and wetlands in which their life cycle began. All odonates lay their eggs in water, and it takes time – from a few months to a few years – for the larvae to go through the individual stages of molting until they are large enough to begin the transformation from nymph to adult. When the nymph is ready, it crawls out of the water onto rocks, emergent vegetation, or nearby tree trunks or plant stems, and then bursts out of the larval shell through a hole in its back, using gravity to pull itself free. I have seen various dragonflies in the middle of this process a few times; I had never witnessed the full transformation as it takes a few hours for the dragonfly to become ready for its first flight. However, when I arrived at Mud Lake on a sunny day in mid-May hoping to find some warblers, it was a mass emergence of at least 50 individual dragonflies that engaged my attention, and I was able to observe many individuals at different points of the process.
By the time November arrives, all but the hardiest of insects have vanished, leaving only those few species that are adapted to the cold temperatures of mid-autumn in Canada. The last dragonfly on the wing here in Ottawa is the Autumn Meadowhawk, a small red or brownish dragonfly with very little black along the abdomen and yellow or brown legs. It is these two traits that make them easy to distinguish from other local meadowhawks – the other common species have distinct black markings on the abdomen and black legs. The most similar dragonfly in our area is the Saffron-winged Meadowhawk, which also lacks distinct black abdominal markings. However, the Saffron-winged Meadowhawk is larger, usually has a noticeable amber-coloured tint to the leading edge of its wings, and has black legs with brown stripes. In addition, most of the other meadowhawk species are gone by mid-October.
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.
By early July a variety of dragonflies and damselflies are on the wing, although some of the early species – such as the Beaverpond and Spiny Baskettails – have already finished flying for the year. This is usually the time of year when I start focusing on odes on afternoon outings in addition to enjoying them as distractions on morning birding outings. While some of the best ode-hunting can be found along the Ottawa River (including Mud Lake, Andrew Haydon Park, Petrie Island, and Morris Island) there are some great spots in my own backyard, including Bruce Pit, Stony Swamp, and the Eagleson storm water ponds (which will be the focus of a separate post of its own). Bruce Pit is a particularly great spot for odes, and some unusual ones have turned up there including Swift River Cruiser, Black Meadowhawk and Black Saddlebags. Eastern Red Damsels used to breed there prior to 2010, and I decided to spend the afternoon of July 4th wading around the edges of Bruce Pit to see if I could find any. Unfortunately, the area where we used to see them (and odes such as Amber-winged Spreadwing and Saffron-winged Meadowhawk) has become overgrown with cattails and phragmites over the year, so I wasn’t sure it was possible to walk along the shore where we used to go a decade ago (I can’t believe it has been so long …. apologies to those who have never visited my old LiveJournal site, back in the days when I used to host my images on Photobucket which no longer allows free hosting and has hidden many of my images).
On Saturday, July 3rd I accompanied the McNamara Field Naturalists on their first in-person outing since the latest Stay-at-Home Order ended on June 2nd. Ontario entered Stage 2 of its reopening plan on July 2nd, which raised the number of people who could attend outdoor social gatherings and organized public events to 25 people (as well as allowing haircuts and personal care services again). Although I am not a member of the McNamara Field Naturalists Club, which calls Arnprior home but whose explorations include a large swath of the Ottawa Valley, one of my friends happens to be in charge of putting field trips together, and asked if I wanted to help lead a dragonfly walk. I said yes, and suggested Morris Island as it’s a great place to find all sorts of odes, including several flashy skimmers and clubtails that can be found perching in the vegetation and along the trails. I was thrilled when my mentor Chris Lewis joined us, as it would be easier to find some more of the unique species with a couple of knowledgeable people looking.
On June 20, 2021 I accompanied fellow OFNC members Derek and Erik to the Carp Barrens Trail off of Thomas Dolan Parkway to assist them in a survey of breeding birds and other wildlife. Because of the sensitivity of the ecosystem and number of at-risk species which breed here, this trail is closed to the public during the summer. In order for us to access the site, Derek had acquired a permit to allow us to look for unique breeding birds such as Black-billed Cuckoo, Eastern Towhee, Common Nighthawks and Whippoorwills. Derek and Erik started around dawn to listen for both nightjars, but heard none. I joined them at 6:00 am while they were still walking along Thomas Dolan Parkway, and together we entered the trail system.
The trail follows a rocky outcrop around a long slough. Many birds were already singing, and we heard the typical open field and woodland edge species: Field Sparrow, White-throated Sparrow, Veery, Scarlet Tanager, Rose-breasted Grosbeak, and many warblers, the best of which (in my humble opinion) included two Pine Warblers, two Yellow-rumped and two Nashville Warblers.
The beginning of June arrived with plenty of warmth and sunshine, and I couldn’t wait to go back to Marlborough Forest at the peak of butterfly and dragonfly season to look for new species living there. Last year when I started going to Marlborough Forest in mid-June, I kept seeing large, dark dragonflies – almost certainly emeralds of some sort – zipping down the shadowy trail before the sun had fully risen above the trees. I never had my net on me when I saw them on my early-morning birding walks, so I was unable to catch one to verify their identity. This time I was prepared for these dawn-flying dragons, and brought my net with me. I had already added one dragonfly to my life list, the Ocellated Emerald at Trail E4 last year; was it possible that there were other species of interest here?
My first summer visit to Trail E4 occurred on June 6th. Although the morning started out cool, it quickly warmed up. The usual birds were singing along the trail, including all the Red-eyed Vireos, Eastern Wood-pewees, Eastern Kingbirds, Veeries, and the Tree Swallows that were missing from my mid-May visit. I heard seven warblers (Ovenbirds, Northern Waterthrushes, Black-and-whites, Nashvilles, Common Yellowthroats, Black-throated Greens, and a single Magnolia Warbler), two Chipping Sparrows, a Field Sparrow, and a Blue-headed Vireo singing in its usual spot in the large open area devastated by motor bikes and ATVs.
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.
On May 15th I decided to try a new trail in Marlborough Forest. I was mainly looking for butterflies, as dragonflies weren’t all that numerous yet. Dreaming more of elfins and commas than dragons and damsels, I parked on Kettles Road near the Black-billed Cuckoo site from last year. I headed south, and almost immediately found myself in an area with four species flying: Mourning Cloak, Northern Spring Azure, Henry’s Elfin, and Gray Comma. The sunny day was perfect for looking for butterflies, and I ended up finding quite a few, especially in the open cedar woods where they were resting on the trail.
It’s been a good season for hard-to-find dragonflies at the Eagleson Ponds. Ever since I discovered both Eastern Amberwings and Saffron-winged Meadowhawks here in 2017 I’ve been spending more time here later in the day looking for odes, rather than doing a quick search for birds first thing in the morning before heading elsewhere. The Covid-19 pandemic has made that even easier for me, as I am still working from home and can get out at lunch time for a quick check when the temperature has warmed up enough for many odes to be flying.
Mid-summer seems to be the best time for seeing a variety of odes at the ponds. While I have seen a few early-season species here, such as the Taiga Bluet and Spiny Baskettail, most odes that breed here don’t emerge until later in the summer. I’m not sure if the late start to spring had anything to do with it, but up until the end of June I found very few dragonflies here – skimmers are usually abundant throughout the season, but on June 30th I recorded a single Dot-tailed Whiteface and a single Twelve-spotted Skimmer along with a couple of Common Green Darners and Prince Baskettails that refused to land. Even the Eastern Forktails seemed down in numbers.
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.
