Hi, these little flies (2-3 mm) appear every year in my garden in a sheltered sandy area with a bigger colony of antlions Euroleon nostras and a smaller one of the Spiny Mason Wasp Odynerus spinipes.
I am not able to identify the fly and hopefully someone may help.
Maybe the flies are associated either with Euroleon or Odynerus? Thanks a lot!
Greetings, Eric
