This topic is about the Insect Order Odonata-Zygoptera

Beautiful damselflies are a priceless part of a trout stream's aesthetics, but they matter little to our flyboxes. The adults are too good at flying to end up in the water where the trout can reach them very often, but their nymphs are welcome prey at times.

Damselflies and dragonflies are in the same order, Odonata, but they are taxonomically separated on an obscure level not built into this site, the suborder. Damselflies are in the suborder Zygoptera, the scientific name by which they're most known. None of that will help you catch trout, but it explains what the hyphen in this page's title is all about.

Biologically, damselflies are similar to dragonflies (Odonata-Anisoptera) in most of the ways that matter to the angler. Read more...

Today I was collecting nymphs in the Poconos with Gonzo when I spotted an interesting-looking spinner in the air and it landed next to us on a piece of grass. I grabbed it and tossed it in my bug box, and we both took a closer look.

It was a male spinner, perfect for identification, and it seemed to belong to a species of Ephemerella that neither of us recognized. The form was similar to invaria, more sleek than subvaria or Drunella. It was long, a big size 12 probably, but very thin. It had three long, elegant tails, and would generally have been a very photogenic mayfly.

I was looking forward to getting it under the camera and microscope to figure out what it was. But when I got home a little while ago and was looking through my bugs, it had disappeared!


I found a detached spinner wing of about the right size, dangling out of the mouth of a big damselfly I had added to the container. D'oh! Despite the stress of restriction to my container, and the fact that its wings were messed up, my crippled damselfly apparently hobbled its way over to my prized spinner and ate all but one wing.

J a good way to bring home adult odonates is in a paper triangle envelope. take a normal sized sheet of paper and divide equally into quarters... cut and keep in a dry place in your vest. when you collect an ode, take a quarter sheet and fold it to make a triangle, with the edges overlapping. stick the insect inside and fold the edges over to keep it in. you can even label the envelope. if you keep it in a safe place you can bring them back alive (crushproof and out of sun).

if you put more than one in an envelope you will likely have the same issue with them eating each other. odes tend to pull everything to their mouths which leads to shredding it.
