Aphid midge larvae with rusty plum aphid - Aphidoletes

Aphid midge larvae with rusty plum aphid - Aphidoletes
Dinuba, Tulare County, California, USA
June 18, 2005
On plum. This is an important predator of rusty plum aphid.

Moved
Moved from Aphid Midge.

Moved from Aphidoletes.

 
How was the species ID made?
How do you know it's this species rather than one of the other three Aphidoletes spp., which are also predators of aphids?

 
species unknown
I made an unwarranted assumption. Is there any way to tell, without rearing the larvae to adult? If I rear some to adult, what is a good reference for checking?

For now, I should move this back to Aphidoletes.

Thanks.

 
not sure
I'm certainly not an expert. The question just occurred to me when I read in Gagne that all Aphidoletes species are predaceous, and I thought I remembered the BugGuide images being identified to species. The reference Gagne points to for this genus is:

Harris, K. M. 1968. A systematic revision and biological review of the cecidomyiid predators (Diptera: Cecidomyiidae) on world Coccoidea (Hemiptera-Homoptera). Trans. Roy. Entomol. Soc. Lond. 119: 401-494

...but I don't know if that includes all four species.
