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!

Hello,
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.
