Posts: 1776		Hey folks! Hope all is well. I've been on warmwater ponds doing underwater video work. Haven't chased trout in a while. But I did video a small brown being narfed by a larger one! Never know what might happen down there.

Anyway, I have been working out shooting warmwater aquatic microinverts, and I came across these tiny caddis. They are likely fairly early instars as they are minute, and were caught beneath ice cover. They swim quite well with their long bristled oar-like legs. Any guesses?

Posts: 1776		Hi Dave, That would make sense. They are tiny -the smallest I'm guessing 1-2mm, the one pictured maybe 3mm. Ah!...The one in the picture got wedged between the glass sheets that made the tiny aquarium I was using. That gap is 2mm -so 2mm is the height on the anterior end of the case. So, yeah, I think 3mm to 4mm for the length of the larger larva.

They are, apparently, pretty common in the Elodea and coontail here.
