Hex Mayflies
Hexagenia limbata

The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.

Clostoeca disjuncta (Northern Caddisfly) Caddisfly Larva Clostoeca disjuncta (Northern Caddisfly) Caddisfly Larva

This one was surprisingly straightforward to identify. The lack of a sclerite at the base of the lateral hump narrows the field quite a bit, and the other options followed fairly obvious characteristics to Clostoeca, which only has one species, Clostoeca disjuncta.

27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

Jason, I work for a not-for-profit company, Professor Garfield, which, in conjunction with the state of Indiana and Ball State University, is putting together an educational web-site for migrant children. We are building science modules. One of our needs for our life cycle modules are photo/video images of dragonfly nymphs, eggs, and dragonflies laying eggs. Would you give permission for us to use your video/photo of a dragonfly nymph? Do you have and could we use any other dragonfly life stage images you have?

Best to you-- Marsha Jacobson

Marsha, you might PM Jason directly. I don't know how busy he is, but if he's in the field he might not check in immediately. A PM may show up on his email, alerting him to your request.
