Pteromalid

Pteromalid
Canter-Berry Farms, King County, Washington, USA
August 3, 2010
Size: approx 1.5mm
Found lots of spider egg sacs attached to blueberries while sifting through about 25 pounds of them. I cut most of them open to see what was happening inside and one of those egg sacs contained this tiny, metallic green wasp. All the spider eggs were missing; guess the wasp larva ate them??

Pteromalid…
This is a pteromalid chalcid wasp based on the wing venation, coloration, sculptured head and thorax, and antennae. There is a wide host range for this group, but I'm not sure spider eggs were the target in this case. A hyperparasitoid is also a possibility. Nice set of pics, Mandy.

See reference here.

 
Thank you, Ross!
Will move to pteromalid section. This stuff is so amazing-- so much going on in such a small little space! I hadn't even thought of a hyperparasitoid (mostly because I don't know much about wasps OR parasites, haha!) Thank you for taking a look at these, Ross. :-)
