wasp - Idris

wasp - Idris
Cross Plains, Dane County, Wisconsin, USA
September 5, 2010
Size: ~1mm
I just came across some photos that looked like this yesterday but I don't remember where in the guide they were. Lots of tiny wasps are showing up now in the sweeps.

Moved from Scelioninae.

Moved from Ceraphronidae.


Moved from Chalcid Wasps.

Not Chalcidoidea
Most likely Ceraphonidae. Possibly Scelioninae (would need to see wing venation under the microscope.)
These little guys especially brachypterous can be difficult.

opinion of J.D. Pinto:
"Not Trichogrammatidae. Possibly Eulophidae. Some eulophids have 3-seg. tarsi, but suspect there is a 4th seg. being missed."

Moved from Trichogrammatidae.

Moved from ID Request.

Meets the criteria for this family including antennal configuration and 3-segmented tarsi. This is an example of a short-winged individual - wingless versions are also known, but are comparatively rare.
