 Hi,

I found these Tabanidae larvae in the mud of a pond.
Are they larvae of Tabanus ?
Belgium, 23-10-2018, larva 1 of about 35 mm, larva 2 of about 40 mm

Thanks
Christine

 Tabanus it is, and I think it is autumnalis

 When having a closer look, I'm even convinced that this must be T. autumnalis for sure. The first thoracic segment is densely pilose laterally and there is curved hairy patch on the anal segment. No other NW European species is like this. I have attached the drawing from Jezek 1977.

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
