Found in a glass jar with garden soil, 6mm long. Vienna in June

---

Pachygaster sp. and most likely P. atra. for the ventral hairs appears to be swollen at the end.

---

In my garden, so far I could document 2 different Pachygaster species (P. leachii the other one), but P. atra is the most common stratiomyid here. Are these larvae good to separate based on the hairs?

Dear Lorin
yes, the distinction can be made by using the ventral setae. In P. atra these setae are distally thickened and in P. leachii they are not. In some older papers (e.g. Rozkosny 1973) it is, in my opinion, wrongly written as dorsal setae.
