Browsing Bliss Awaits You

It appears you're using Internet Explorer or an early version of Edge, which is a bit like watching a black-and-white TV with "rabbit ears." You're missing symmetry, joy and actual knowledge — not only here on my website but across the internet. I suggest you upgrade to Chrome or Firefox. You’ll discover a lot more nature, maybe even actual rabbit ears.

Little else in nature rivals the scintillation, the explosion of green, expressed in the eyes of the dragonflies we call “Emeralds.” Here’s how it usually happens: You’re squishing around in a spruce bog or walking a woodland trail, and you notice the laser glow from 30 meters away. It seems to emerge from some other dimension. And it is zooming a determined course toward you. This is a state of bliss and anticipation for any self-respecting dragonfly watcher (dragonflyer).

That particular emerald above, a male Ocellated Emerald (Somatochlora minor), was looking for sex. Or so I assume. On the final day of the Dragonfly Society of the Americas meeting in Saskatchewan, I was knee-deep in a gentle flow of water and sedge when I noticed a female Ocellated Emerald, hovering, dipping her abdomen in water, rising a couple of inches, then slapping her abdomen against a mossy bank. She repeated this sequence in rapid fashion for about three minutes. She was laying eggs. I got close enough for video, which you’ll find below. But after she’d vacated the spot, he showed up, hovering, and almost certainly looking for her. (Dragonflies mate multiple times.) That’s when I got the flight shot.

This is how it went during the DSA meeting. Nearly everything cooperated – the weather (mostly sunny), the community of Prince Albert, and most of all our airborne subjects. We encountered 52 species of dragonflies and damselflies, including a new provincial record for Dorocordulia libera (Racket-tailed Emerald) landed by Cary Kerst. I’ve posted the list below (after the Dorcas Copper). Highlights included eight species of Somatochlora (those emeralds); eight species of Aeshna (mosaic darners), including A. sitchensis (Zigzag Darner), a lifer for me; and critical new encounters with Stylurus notatus (Elusive Clubtail) and S. intricatus (Brimstone Clubtail). (I was proud to have found both as adults.) Our gratitude goes to meeting organizer Dave Halstead and his crew of dedicated volunteers, who pulled off one of the most hospitable DSA meetings in memory.

After the emerald video, I’ll leave you with two images of Dorcas Copper (Lycaena dorcas) from a bog up here. Yeah, I bushwhacked to get there. Onward toward Montana, Baird’s Sparrows, and Ruth!

    That’s no Ocellated Emerald…it’s a new-fangled drone, so watch out! Not only is it winged, it’s armed!
