Hi,

I'm not sure if I have ever seen this kind of golden Tachinidae before. July 17. 2010 Loviisa, Finland

Ahh, lovely ... I think they are much commoner in your part of the world than they are here. Nikita gave me one from Moscow region and Jaakko sent me 2 from Finland, so I have a few here in my collection from the north-east of Europe :)

They really are a lovely tachinid and there's not much that is as golden as Leskia aurea :)

Hi Chris (and Jari),

Not that commonly seen on open, but numerous when you rear the host, especially Synanthedon spheciformis. I think this must be more boreal species as the host is commonly found from young Alnus or Betula shoots, which you simply donīt have as abundantly as we in the North (on our clearcuts, especially... :()

I collected this weekend Lydella ripae male, Leiophora innoxia, Phasia hemiptera and all three species of Dinera among others while being out with the kids. Not bad. L. innoxia was a real treat!

Take a photo to the L. innoxia specimen, if possible. ;)

Yeah, I only ever had L.innoxia twice here - from Malaise traps :)

Hi,

Fresh from the press. Unfortunately I donīt really have equipment to take proper photos, this is just shot through the scope with a pocket camera... Wing cell is open, although looks closed in the picture, arista thickened to half and there is a thin line of silver dusting on each tergite margin. Size 5 mm.

The biotope is cool: some 3 km from where I live there is apparently an old military grounds with a huge, open, low vegetation meadow. Very hot landscape with abundant orthopterans, including Oedipoda caerulescens numerously. I caught this by sweeping the low grass.
