This topic is about the Insect Order Odonata-Anisoptera

Dragonflies and damselflies are in the same order, Odonata, but they are taxonomically separated on an obscure level not built into this site, the suborder. Dragonflies are in the rarely mentioned suborder Epiprocta, and within that suborder is the infraorder Anisoptera, the scientific name by which they're best known. None of that will help you catch trout, but it explains what the hyphen in this page's name is all about. Read more...

Our great discussion of hellgrammites included a very interesting little tangent about the feeding habits of dragonflies which I'm copying into the dragonfly section.

This is pure trivia, and non-hellgrammite related, but Brett's comments on the discards of bats and nighthawks reminded me of an experience on the Delaware. I was fishing with a guide and we saw several mayfly wing and thorax combos floating along with missing abdomens. At first we hypothesized that a small trout must have bitten the abdomen right off. Then we saw a dragonfly intercept a sulphur mid flight, chew up the abdomen almost instantly, and let the wings and thorax fall, helicoptering like a winged maple seed. This is probably not news to the entomologists here, but some everyday anglers might not have yet noticed this phenomenon. Gonzo, do we have a wing and thorax tie yet?

Louis,

I haven't found trout to be that interested in dragonfly discards, but you never know. I am reminded of an evening on Mud Run when my fishing partner's fly mysteriously ascended skyward, towing a good portion of the tip of his fly line. His fly, while having a minimal effect on the trout we were pursuing, was sufficiently convincing to a large dragonfly--a testament to the powerful flight and lifting capabilities of these insects!


I love watching dragonflies feed on mayflies, but I admit I've never noticed the falling discards. I'll keep an eye out for them next season. A good photo sequence of the phenomenon would be awesome, but I think my photography skills would need to jump several orders of magnitude to capture such a thing in action.
