June 25, 2010
Size: 1 mm
Siphoninus phillyreae, an introduced species from the palearctic.

What host plant was this on?
I'll make sure to keep an eye out for it and its associate biocontrols in future...

James, I recall the host was most likely a Citrus sp., key lime in particular.

Moved from Whiteflies.

good call-Ash whitefly caused havoc in Ca and Nv until parasitic wasp brought it down
