These are the first stoneflies of the year to appear in most parts of the country, and often the first aquatic insects noticed by the angler. Their dark brown or black bodies are easy to spot against the snowbanks where they crawl around.

Capnia and Allocapnia are probably the most common genera of this prolific family.

I like your site and all it offers. Would like you to come on down to the Southeast and identify our species of mayflies, caddis and plecoptera. Ours are a bit different in makeup than elsewhere and really need cataloging. We constantly are trying to compare our species to the northern hatches and it does not fit into their pattern. We are a month ahead of everywhere else and twice as long in many cases. Some hatches seem to be identifiable and then some defy easy categorization.
