Element Occurrences (EOs) in Georgia: 5
Habitat Summary for element in Georgia: Georgia habitat information not available
A small grasshopper (10-27 mm in length). Brownish in color with black stripe extending laterally from behind the eye down the thorax. Hind tibia are red. The male cerci are triangular. This species has short wings and is incapable of flight, but is a very strong jumper.
May occur within range of M. muscogee. In the lab, species can be separated by the shape of the male cerci, which are triangular in M. chattahoochee and falcate in M. muscogee, and by dissecting and observing male internal genitalia.
This species is known from open savannas/woodlands dominated by longleaf pine (Pinus palustris) and turkey oak (Quercus laevis) among the Fall Line sandhills of western Georgia.
Likely a generalist feeder on herbaceous vegetation.
Like all Orthopterans, the Melanoplus chattahoochee undergoes an incomplete metamorphosis. Adults may be found in late summer to fall.
Walk through savanna vegetation to flush and locate grasshoppers. Catch with a net to confirm ID.
Melanoplus chattahoochee is endemic to the Fall Line sandhills region of western Georgia.
The primary threats to this species come from development and fragmentation of its habitat, combined with a naturally narrow range. Suppression of fire has also allowed woody species and exotic invasive species to encroach on the open habitat needed by this species.
At present, three populations are known. These all occur on public land.
Conservation of this species is best conducted by preservation and management of the remaining habitats where it occurs. Reintroduction of fire into the landscape will help maintain and restore suitable habitat.
