I went out to help with @jonsweetman.bsky.social’s aquatic invertebrate class at Shaver’s Creek, and a curious calamoceratid caddisfly (comb-lipped casemaker) peeked out of its case!

Cold water = slow metabolism. Low light = low plant/algae growth. So the surface looks quiet…
…but under stones, in weed, and along the margins, the invertebrates are very much “in session”.

Using morphological + molecular data from 1,030 freshwater fish, this new paper more than doubled the known diversity of trematode metacercariae (51 species).

European freshwater parasite diversity remains strongly underestimated.🧪🐟
