Sweetflag Spreadwing – OdoNotations

Next Gen Dragon-hunters

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.

‘Tis the Season for Spreadwings

If the first half of June is great for seeing all kinds of pond damsels (Family Coenagrionidae), the latter half is great for seeing all sorts of spreadwings (Family Lestidae). They may not have the bright colours or the variety of hues of the pond damsels, but what the spreadwings lack in colour they make up for with their larger size and the beautiful metallic green colouration of some of the species. Adult male spreadwings are generally one of three colours: metallic green, black, or brown, each developing various amounts of bluish-gray pruinosity on the thorax and tip of the abdomen. They can be easily identified in the hand or in a photograph that clearly shows the tip of the abdomen viewed from above, as each species has paraprocts that are distinctly different in size and/or shape. On the other hand, females and tenerals are generally duller, browner, or sometimes even bronze or orange in colour. Much like female bluets, these spreadwings are difficult to identify in the field; though some can be examined and identified in the hand, others require a microscope. As such, I have never really delved into the difficulties of identifying female spreadwings.

Damselflies in New Places

Damselflies are small odonates related to dragonflies, but belong to Order Zygoptera instead of Order Anisoptera. Unlike dragonflies, damselflies have very slender abdomens, and the forewing and hindwing are similar size and shape. Two of the three families found in eastern North America – the broad-winged damsels and pond damsels – hold their wings above the body, parallel to the abdomen, while perching. The third family – the spreadwings – do not perch horizontally with their wings parallel to the body, but typically “hang” from a perch, with the wings slightly spread at an angle. Adult damselflies are not strong fliers, and generally do not travel far from water. They are most often found in vegetation or on the ground near ponds, streams, and other bodies of water. Because of their small size they can be difficult to see, but the dark wings of the jewelwings and brightly coloured abdomens of some of the pond damsels help aid in observation.

Ode-Hunting in Early July

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).

September Odes – A Summary

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.

Mid-summer

It’s hard to believe that it’s mid-summer now; July is over, August is here, and songbird migration is only a few weeks away. When it comes to insects, I’m not thinking as much about seeing the first species of the season as I am wondering whether each individual (except for the darners and meadowhawks) is my last of the season. There are some species I seem to have missed completely this year, such as Emerald Spreadwing (which has a flight season from mid-June to mid-August), Horned Clubtail (mid-May to early July), Stream Cruiser (late May to mid-July), and any of the hairstreak butterflies (the peak of their flight season occurs in the first half of July). This is the result of a combination of bad luck and bad weather; I missed most of these bugs when I went looking in places where I have seen them before, and when I wanted to return later, the cold, overcast and/or rainy weather on the weekends prevented me.
