Seasonal Observations: Damselflies

After falling slave to Deadline Madness for almost a decade, I managed last summer to redefine “urgency.” (Broadly speaking, the top 3 drop-everything-and-go-for-it priorities are Love. Strawberries. Summer.)

Practically speaking, that has meant jumping into a lake whenever I ride by.

And this week, that has meant noticing how many damselflies are out at Mosquito Lake.

Given the way they fly and frolic like camera-shy fairies, I double-checked with local fishing guru, Brad Knowles at the Pemberton Fish Finder, and he confirmed that they are adult damsel flies. (If you want to know how to tie a damselfly fly, he’s your man.)

And thanks to the fauna geeks at UBC, here’s a little insight into the life and times of a damselfly.

  • You could call them dragonflies and you wouldn’t technically be wrong. They belong to the order Odonata, which contains about 5000 species.
  • On close inspection they look primitive because the Odonata and their ancestors are some of the most ancient of insects.
  • In BC, there are 2 sub-orders, the Zygoptera (damselflies) and Anisoptera (dragonflies). The damselflies are slimmer, often smaller and usually slower than dragonflies, and their equal-sized wings are usually held together above the body. Zygoptera means “joined wings.”
  • Unlike most insects, they can work their four wings independently, making them superb aerial predators. (Take that, mosquitoes.)
  • The adults only live for about one or two months. Many species of damselfly in BC develop rapidly – with an entire life cycle unfolding in just a year.

Based on their  electric blue colour, I’m going to guess that Mosquito Lake has a decent population of Argia vivida  (the vivid dancer) damselfly – one of the province’s red-listed species.

(But I coudn’t get them to stop still for long enough to be sure. Any local experts are welcome to help me out!)

    Thanks to Veronica Woodruff from Stewardship Pemberton for advising that Mosquito Lake’s resident dragonflies are most likely Boreal Bluet, Pacific Forktail, Common Spreadwing and Blue-eyed Darner. (With thanks to John Acorn.) On the must-acquire list of books: Bugs of British Columbia. Veronica says, “Its an awesome book for treasure hunting bugs, good descriptions.” Thanks V!
