Trixa pauciseta (Tachinidae) female
France, Haute-Pyrenees, Luz Saint-Sauveur
5th June 2014. Altitude 1 000m

Another specimen recently degreased (Dexiinae seem to be most prone out of the Tachinidae to suffer this) so the bronze tint is rather artificial. Individuals were sitting on bramble leaves (Rubus) in thick vegetation with grubbed patches of soil due to wild boar, in cool, overcast weather.

T. pauciseta is close to T. caerulescens, but has fewer median bristles and also has a differentiated vibrissa and hairs on the prosternum. I think it is solely restricted to the Pyrenees?
