Cynipidae - Antistrophus - female

Cynipidae - Antistrophus - Female
Blanchard township, Lafayette County, Wisconsin, USA
July 10, 2015
This came from Silphium laciniatum (Compass plant) stems, same as but their appearance is very different. I couldn't find any similar photos in this family; could they be different families?

Antistrophus
This is indeed a species of Antistrophus. Species of this genus aren't easily separable from images, but provided that your host record is correct this is Antistrophus rufus or Antistrophus minor (probably the former rather than the latter).

Moved
Moved from Gall Wasps.

Moved
Moved from Pteromalids.

Cynipid (female)…
See reference here.

 
Geesh...
I'm all mixed up!!! If I say Pteromalidae, it's Cynipidae and visa versa!!! Thanks for the help.

 
Associations…
In your area, this may be a species of Antistrophus. An article here, discusses the relationship between the host plant and other species including gall wasps and chalcids.

 
Yes,
That's from my website. I've read that article several times. I have had an apical gall wasp in a compass plant, but only found it one year and never again.
