grasshopper green - Hesperotettix viridis
6 miles NW Lyons, Boulder County
August 18, 2013
Size: BL ~ 21.5 mm
This green grasshopper was seen in the same general area as the just posted 1147103, in the foothills at about 6400' elevation and about two years earlier. It looks like Hesperotettix viridis, or somewhat like H. speciosus but it doesn't have the pale snow-like markings on face and thorax. Any help with its ID is much appreciated.

Hesperotettix viridis pratensis
which may be a totally different species from typical H. viridis. It tends to be found on greener more herbaceous composites than the other "subspecies" (such as Goldenrod, Sunflowers, etc., as apposed to woody Composites that the other prefers). The pattern is somewhat different, and this one is particularly light (with the dark markings not well developed).

The two are often found in the same areas, but usually on different plants and not really associating with one-another.

H. curtipennis occurs a bit higher in the mountains (mostly further south), and it may just be a short-winged form of this. People collecting in Colorado along the Front Range are in a good position to see what happens when those two meet.

Moved from Short-horned Grasshoppers.

Thanks so much for your ID of this handsome green grasshopper and for your discussion of how it differs from the typical H. viridis. Your help is so much appreciated.
