I found this Tachinidae the 2-9-2003, in the "Fagne of Malchamps" (Belgium).
Is it Nemoraea pellucida?
Thanks

Hi Christine,
I think Linnaemya sp.

---

Could you tell me why you think at Linnaemyia?

---

Nemoraea pellucida has got a characteristic small head. The male has narrower frons than your fly, and the female is black.
I can also add this discussion about Linnaemya here.
;)
If I'm not wrong, of course...

Thanks Stephane

Stephane is correct - it isn't Nemoraea, it's a Linnaemyia (projecting mouth edge, very hairy eyes, pale basicosta) - possibily vulpina (big orange abdomenal side patches and orange femur) :)

Nemoraea males are quite big flies that look superficially similar to Tachina fera but with a slightly flattened abdomen, slightly long thin legs and (as Stephane said) a head that looks a bit too small! ;) The relative body proportions are not obvious unless you have seen them and compared them to the alternatives but when you compare a few photos you'll see the difference :)

Did you find your Linnaemyia on or close to sandy heathland?

---

No, the "Fagne of Malchamps" is a heathland but on a peaty soil (very wet with Sphagnum...). No sand there.

---

Well, I think heathland is enough - Linnaemyia vulpina is common on heaths here in Britain - just the ones I have seen it on are quite sandy under the peat. :)

Thanks a lot for all these precisions Chris

It's vulpina
