Observed 13/08/23 in foothills of the Dublin Mountains in Ireland.
I first thought this was a mason/potter wasp but head wings etc. say it's a fly and underside is bright yellow.

Other than that I have no idea!

it is Tenthredo notha, arcuata, brevicornis or schaefferi. I don't know, which species of this complex occur in your region. Generally T. notha is the most widespread one, T. arcuata is restricted to mountainous areas.

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