How you want your letter signed:  Thanks, Danielle


Dear Danielle,
This is a Caddisfly in the order Trichoptera.  Caddisfly nymphs are aquatic and they are frequently called Caseworms as they construct often elaborate protective cases from twigs, sand and shells.  Since the nymphs are aquatic, we suspect you live near a body of fresh water.  Your submission is the second we are posting this morning from New Brunswick, Canada

  1. The entomologists believe that caddisflies (Trichoptera) are closely related to moths and butterflies (Lepidoptera). Looking at this photo, you can see why they think so, though, of course, they’ve got DNA and fossils to go on as well.
