When I decided to take today off it wasn’t my intention, in the beginning, to embark on an all-out “dragon blitz” and search for as many odonate species as possible (or at least as many as I could find until my stamina began to falter); the forecast for the weekend looked terrible, so I wanted to go out while the weather was nice to look for birds in the morning and odes as soon as it warmed up. However, that’s exactly what it became as I started finding some good dragonflies early in the morning and decided to keep visiting different trails where I knew I could find different species.
My morning began with a visit to Lime Kiln Trail, which isn’t a place I visit very often. However, a Mourning Warbler has been heard singing away there for a couple of days now, and I thought I would try to find it. My walk started out fairly quiet, but I saw a Veery on the ground and a Common Raven flying overhead right near the beginning of the trail, and heard a couple of Red-eyed Vireos and a Brown Creeper in the woods.
Once I reached the large burn site the activity picked up. I heard two Alder Flycatchers and saw two Eastern Kingbirds. I wasn’t expecting to find either House Wrens or Brown Thrashers so close to home, but the open burn area was home to many individuals: I counted at least six House Wrens and at least three Brown Thrashers all in full song. The bird life was incredible, though I did not hear the Mourning Warbler.
It started warming up after 9:00 and shortly after that I noticed a few Racket-tailed Emeralds were flying about. I gave up on finding the Mourning Warbler so I decided to stop in at Sarsaparilla Trail before trying to track down my next target, the Eastern Red Damsels along the Transcanada Trail near Highway 417. Brian Mortimer, who had discovered the colony of this rare and local species last year, had seen over a dozen of them on June 3rd and after failing to find them last year with Chris Lewis, I wanted to try again for this pretty little red damselfly. I think it was then that I decided to embark on my Dragon Blitz, as I knew three different whiteface species could be found along the boardwalk at Sarsaparilla.
I was surprised not to see either Frosted or Belted Whiteface hanging out in the cattails or along the boardwalk itself; only six days ago I’d had all three whiteface species here. I left the pond and continued my walk through the woods. There were some nice sunlit clearings where I found a few insects on the wing, and I was happy to see my first Taiga Bluets of the year.
This image shows the spectacular turquoise colouring of the eyes and the lower half of the thorax. This is one of the easier bluets to identify because of its unique turquoise-green colouration below. It also has a large black area on the distal half of its abdomen that the other black and blue bluets lack.
I thought there might be some more odonates flying in the sunny open meadow next to the outhouse, which is a great place in general to look for insects among the long grass and flowers throughout the warmer months. I wasn’t disappointed – I saw my first Widow Skimmer of the year here (a brown and yellow teneral) as well as a mostly mature Twelve-spotted Skimmer – it still has some yellow visible on the sides of the abdomen.
Several Racket-tailed Emeralds were patrolling the large clearing, and a few of them perched in the vegetation where I got some nice close-ups. This mature individual has bright green eyes:
I found a couple of Dot-tailed Whitefaces in the clearing as well. One was perching in the grass, but another was resting on a leaf. Here you can see both of the features of its name. While I confess that I don’t find such overly descriptive names particularly appealing (I prefer more imaginative names like Halloween Pennant, Ebony Boghaunter and Stygian Shadowdragon!), they do come in handy in trying to identify insects on Google! This was the first and only dragonfly I have been able to identify with a Google search.
I reached the parking lot and was heading to my car when a large dragonfly circling the area caught my attention. I hadn’t expected to find any dragonflies worth catching along the trail, so I had left my net in the car; as it appeared to be a darner I decided to grab the net and catch it. The dragonfly must have sensed my plans for at that point it decided to land on the side of my leg! Of course as soon as I turned to look at it, it flew off. It was likely a Harlequin Darner, a species with a well-documented habit of landing on people, and if so, it was the first one that I’d seen at this trail. I wasn’t able to see where it went, and, hoping it would come back, fetched my net from the car and then spent some time loitering in the parking lot.
While I was loitering, a couple of insects on one of the large rocks near the trail entrance caught my interest. The first was a metallic green Six-spotted Tiger Beetle, but the second insect was a dragonfly, and I did a double-take when I realized it was a clubtail. I have never seen a clubtail here at Sarsaparilla Trail before, which made this sighting an exciting one. I could tell that it was one of clubtails in the Arigomphus genus by its pale claspers, turquoise eyes, and the wavy orange spots on the sides of segments 8 and 9. Only when I got close enough did I see that there was a small yellow spot on top of the 10th segment and that the small, forked claspers were completely wrong for Horned Clubtail, which is the Arigomphus species that I find most often. Instead this was a male Lilypad Clubtail!
I got a little too close to the dragonfly and caused him to flush; fortunately he landed on the leaves on the ground.
I netted him, examined him in the hand, and put him on a rock when I was done. To my surprise he stayed there.
Here you can see that the claspers are quite small and inconspicuous compared to the large, spiky-looking claspers of the Horned Clubtail.
I was truly thrilled with this discovery, as it was the first Lilypad Clubtail I’d seen at Sarsaparilla Trail. Given that this species prefers marshy ponds and slow streams with mucky bottoms and abundant aquatic vegetation, I’m surprised this species hasn’t been seen here more often.
By the time I was done photographing the clubtail it was clear that the darner wasn’t coming back. Pleased with the day’s sightings so far, I headed out to the Transcanada Trail where I hoped to have equally good luck in finding the Eastern Red Damsels.
