it is a larva of a Chironomidae (subfamily Tanypodinae) in the prepupal stage. For an identification to genus or species level, you need to study the larva in more detail, especially the head and the anal claws. As it is in the prepupal stage the thoracic horn in the thickened thorax can be studied as well for a positive identification. It is impossible to tell which genus/species. Try adding a photo of the thoracic horn, a detailed photo of the head or the anal claws, or else you can send the larva to me and I will try.

Dear Obonaj This larva is a difficult case. Although the larva resembles a Zavrelimyia (and Paramerina), for it has an additional extension at the innerside of one of the claws on the posterior parapods, the habitat doesn't quit fit. As far as we can tell, there has been no record of any Tanypodinae in a tree. Besides that Zavrelimyia is genus known to occur in flowing surface waters (brooks, springs, lowlandrivers) and Paramerina in smaller, standing waterbodies. None of them known to occur in trees. So this may be an interesting specimen. You better ask some specialists on this matter. I have asked a dutchmen (H. Vallenduuk) who previously wrote a book on Dutch Tanypodinae larva, but he didn't knew the species either. He told me that Peter Langton is the best men to ask. |
