Extremely Tiny Wasp? - Cratomus

Extremely Tiny Wasp? - Cratomus
Eugene, Lane County, Oregon, USA
July 4, 2018
Size: 2-3mm
I saw this very tiny bug on the railing of a bridge. It was very small, so I'm glad it wasn't skittish (which makes me think maybe it wasn't a wasp). The head is a very strange shape.

I agree ...
.. with Ross. This certainly is the pteromalid genus Cratomus, although I can't put a species name to it. The western species Ross mentioned is known only from Colorado I believe, and has not yet been recorded from the Pacific coast. The species C. megacephalus is known from Europe and the eastern US - perhaps it reaches further west? And of course, it could easily be an undescribed species.

Cratomus…
This may be the only known western NA species, C. cancellatus. The other two species are eastern in distribution.
