Hello,

A Coenosia found in a forest, the August 07 2014, in France, Clairmarais,
Maybe Coenosia testacea ?

More likely Coenosia infantula, if it is in the testacea group (hard to count the proepisternal setae from these pictures).

Thanks you, Stephane ! :) (and sorry for very late reply !)

I see a little bit of red on the face on certain angle, this should not say Coenosia testacea ?

The orange should be on the anterior part of frons, and the genae are too narrow for testacea. But there are some ambiguous cases, I must admit.
