Pennypack Ecological Restoration Trust, Montgomery Co, PA.
Found along a grassy path through a meadow.
This pair seemed very interested in each other. Courtship?
Red-legged grasshopper (Melanoplus femurrubrum)
Melanoplus sp. cf. M. femurrubrum (Orthoptera: Caelifera: Acrididae: Melanoplinae: Melanoplini). South Run power line cut, Fairfax County, VA 26 September 2012
Special thanks to Dave Ferguson for confirming that this is a "blue form" of the Red-legged Grasshopper, Melanoplus femurrubrum, and a male. Apparently they are not uncommon in arid habitats.
