Northern Spreadwing – OdoNotations

Richmond Lagoon Damselflies

I often visit the former Richmond Lagoons (now called the Richmond Conservation Area) around late June or early July to look for spreadwings, as this is one of the best places to find five or six different species. It’s one of the few places I can find Lyre-tipped Spreadwings easily, and in 2023 I found another difficult-to-find species here, the Emerald Spreadwing. Both spreadwings are listed as “uncommon” in the Ottawa checklist, but the Lyre-tipped Spreadwing is also designated as “local,” having a special preference for shallow marshes and vegetated ponds completely in the open, particularly those that often dry up during prolonged droughts. While the Lyre-tipped Spreadwings typically disappear with the water, they are also quick to appear in temporary flooded areas such as farm ponds, gravel pits, and artificial ponds. While Emerald Spreadwings also inhabit densely vegetated, shallow wetlands, they can be common in shrubby or forested areas a distance away from their breeding ponds. Emerald Spreadwings are not usually successful in wetlands where predators such as fish or dragonflies are common, which may explain why they can be tough to find.

Road Trip: Odes in P.E.I.

We only had one night on P.E.I. (which we spent at a hotel in Summerside across from the harbour) so we didn’t do a lot of hiking or exploring. We spent the day we arrived touring the western side of the island, where I thoroughly enjoyed the birds and views of North Cape, and the day of our departure exploring the eastern half. It wasn’t until the second day that I saw any odonates – we visited the Anne of Green Gables Museum and the birthplace of L.M. Montgomery, had lunch in Charlottetown, then drove across the island to East Point before catching the ferry at Wood Islands to Nova Scotia. When we reached the museum I immediately decided not to join my dad and step-mom on the tour: there was a pond on one side of the driveway, and a small marshy wet spot on the other. I could finally do some ode-hunting!

Odonates on the Wing: October and November 2023

By October I’m thinking about putting the net away for the season. If it is still warm at the beginning of the month, I will usually take the net out as long as I’m still seeing darners and small bluets around. Once I’m seeing nothing but meadowhawks, however, it’s time for me to declare an end to the season and put my gear away until the spring. This year the first week of October was very warm, with temperatures reaching 30°C; they then returned to seasonal for the next week with temperatures in the mid-teens. By the end of the month temperatures were in the single digits during the day and falling to below zero overnight, bringing an end to all but the hardiest of dragonflies. That title belongs to the meadowhawks, in particular the Autumn Meadowhawk (Sympetrum vicinum). It is no coincidence that it is the latest-flying dragonfly in many areas of the northeast….sometimes by several weeks. Once called the Yellow-legged Meadowhawk, it was renamed in 2004 by the Dragonfly Society of the Americas because mature individuals often have brown legs instead of yellow and because it persists so long into the fall. It is the only dragonfly in our area with entirely brown or yellow legs (never black), making identification relatively easy. And it is the only species you are likely to see in Ottawa in November!

The Odes of Late Summer

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.
