Acorn Plum Wasp Gall - Amphibolips quercusjuglans
This gall had dense, red flesh. It had a small cell in the center, which appeared to have several larvae in it. I always thought these galls had a single larva in the center cell, so am not sure why there appears to be many in this one, unless it was parasitized? The gall did have a crack in it, which is how I was able to pry it open. The outside of the gall was brown and dark red.
Habitat: Spotted on the ground (detached) in a mixed forest, but in an area dominated by oak.
