These larvae and 1 single pupa was found on littoral stones in the river IJssel at Kampen, The Netherlands (24.iv.2024) and I can only see any resemblance with Elliptera omissa (or perhaps Elliptera hungarica of which I have no description). I have also checked with eastern Palaearctic species in Podeniene et al (2021) and they look quit similar. Except for the pigmentation on the anal lobes in the larvae it all seem to fit. The larvae of E. omissa supposedly do not have any pigmentation but I think that may have been a misjudgment, not sure though. Other Elliptera species do have similar pigmentation of the anal lobes (Podeniene et al 2021). The head is alo entirely black.
So, is there anybody that can verify my specimens with Elliptera, omissa or hungarica? and is there any recent paper describing either of these 2 species?
Thanks
