Illustrations show variation in the shape of the gonostylus which may be useful and visible under a microscope. You should also compare to Ablabesmyia peleensis, a species which has been recorded from Europe but does not appear in European keys. Edited by John Carr on 05-05-2018 04:24

I like Chironomids but i only ever find keys to larva from angling/fishing journals. Can you recommend a publication? I remember finding something from an expert in Florida but the price for the book is way too high - somewhere around 600 dollars? And he may not cover Euro species anyway. i saw your post at bugguide (node 393504). I found this on a tree next to a pond. I nicknamed it ghost chironomid because it looks transparent white in the sunshine. I lost it three times, then it landed in front of me Edited by johnes81 on 05-05-2018 10:47 John and Nini.

Hopefully we can pinpoint a species. attachment one = antennae. the tip of the antennae seems to be widened with white material. johnes81 attached the following image: [52.71Kb] John and Nini.

Member Location: Berlin, Germany Posts: 1978 Joined: 15.10.16	I wonder if this is Ablabesmyia longistyla. the gonostylus is not longer than the gonocoxite but it is even in length. vide attachment photo I do not think that it matches A. monilis and i don't have drawings of A. phatta or A. peleensis. I see drawings for A. longistyla and A. monilis in a pdf entitled "Revision of the Genus Ablabesmyia in Korea". johnes81 attached the following image: [59.86Kb] John and Nini. Naturalists not experts.
