Family Eulophidae
4 subfamilies with >830 spp. in ~110 genera in our area and TBA spp. in >330 genera worldwide(1) (numbers in(2) may be significantly outdated. =v=)
The 4-segmented tarsi helps distinguish this chalcid from the very similar pteromalid group. These wasps also shrivel up badly after death which is also a characteristic of this family. Most species are primary parasitoids of hidden larvae (e.g. leafmining orders such as Lepidoptera, Hymenoptera, etc.), and some are hyperparasitoids as well. The host range is very diverse. (Comment by Ross Hill).
Other features: dark metallic coloration, 4-segmented tarsi with protibial spur short and straight. Antennae with 2 to 4-segmented funicle, (i.e. antenna at most with 10 segments).
