Respected colleagues, I need a help in identification of some aquatic invertebrates, which I found in little stream in Serbia, on the bottom of stones. Here are the photos of four (or maybe three) species. Thank you in advance.
1st one is aWormslug (may be Boettgerilla sp.); 2nd and 4th are perhaps caddisfly larvae (or any lepidopteran larvae); 3rd one looks like an aquatic isopod (pillbugs), hard to guess the taxon though.
Hope it helps
Regards,
Dr.Abhishek Mukherjee
First : Great Grey Slug
Second : Lepidoptera larvae
Third : Isopoda
Fourth : Larvae ., It's really hard to guess
The specimens of the second and fourth photos belong to the same genus of trichoptera, the isopod in the third photo is a terrestrial isopod.
Picture 2 is most probably a Rhyacophila (Insecta, Trichoptera) of the Prosrhyacophila type.
Agree with Jean Paul, 2nd and 4th photos are Rhyacophila spp. (lato sensu), Trichoptera larvae.
