Thelaira solivaga (Harris, 1780)
Scientific name: Thelaira solivaga (Harris, 1780)
Common name:
French name:
Order: Diptera
Family: Tachinidae
Wingspan : 8-11 mm.
Biotope: Meadows, hedgerows, woodland edges.
Geographic area: Europe, Asia east to eastern Siberia.
Observation period : June to August.
Tachinidae are flies whose larvae parasite other insects. They show a prominent post-scutellum and the M1 vein of the fore wings which suddenly curves.
Thelaira solivaga shows an elongated abdomen, long legs, short antennae and hairless eyes.
The abdomen generally bears a black median band bordered by white, black and orange spots. The base of the wings is orange.
The median tibia bears three long antero-dorsal setae.
There is a possible confusion with Thelaira nigripes, Fallén, 1817. This last species, which is given as more common, only shows two antero-dorsal setae on the median tibias.

Thelaira sp.
Having no clear view of the median tibias I cannot decide for Thelaira solivaga or for Thelaira nigripes. So I will just list this one as Thelaira sp.
