Description

I found this male Mosquito standing on the wall of a container containing a few inches of stagnant, putrid rainwater. The container used to be a pool waterfall feature, but it broke years ago and the pipes at the bottom became clogged.

I caught and killed it.

Photos 1 and 3 had an Auto White Balance applied to it in Photoshop. Photo 3 was also brightened. Photos 4-6 were sharpened and brightened.

Looks like this is a parasitoid on Coyote Bush Bud Gall Midge, Rhopalomyia californica.

I'm just guessing on the species because Russo says that Platygaster californica is the most common parasitoid on the galls and photos I've seen are roughly the same. But I gather that there are a handful of others, some from different families like Torymidae and Pteromalidae.

The other photos show the twig and the wasp apparently ovipositing or getting ready to do that.
