This is a Pteromalidae
not a Eulophidae

Can you clarify which of these images are of the same individual? Only images of the same individual should be linked together. You can reference other images using thumbnail links in the comments, e.g.

(I did this by typing "[ thumb:487318]" without the space after the first bracket, taking the image number from the URL)

Eulophid…
The chalcid in the left image is a eulophid based on the shortened antennae, wing venation, dark metallic coloration, and especially the well-defined subtriangular prepectus. Eulophids are known to parasitize bees. The image on the right is of a different chalcid that apparently emerged from a separate cell. It is not a eulophid, but there is not enough detail here to confirm a family. Do you have any dorsal views of this one?

See reference here.

Eulophid
The wasps emerged from multiple incubated cells, not a single cell. Testrastichus megachilidis is reported from alfalfa leafcutter bee cells?
