Psyllid - Trioza obtusa - male

Psyllid - Trioza obtusa - Male
Cross Plains, Dane County, Wisconsin, USA
March 14, 2010
Size: ~3mm
I found numerous Psyllids in what I think are Balsam firs.

Moved from Triozidae.

Trioza obtusa
The shape of the caudal lobe of the male proctiger will help to distinguish this sp. from similar spp. in the T. frontalis group

The host is Amelenchier, but many triozids have the tendency to overwinter on conifers.

Moved from Cacopsylla.

Cacopsylla sp. --det. R. Gill
Moved from Triozidae.

Moved from Psylloidea.

Balsam Fir...
Balsam Fir (Abies balsamea) is the only native fir tree in Wisconsin, extending to the southern portion of the state (but not indicated specifically for Dane County in the PLANTS county database, though recorded from the county immediately north).
