Federal Protection: No US federal protection
State Protection: No Georgia state protection
Global Rank: G1G3
State Rank: S2
SWAP High Priority Species (SGCN): Yes
Element Occurrences (EOs) in Georgia: 2
Habitat Summary for element in Georgia: Georgia endemic; Ohoopee Dunes sandhills
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 blueish-gray. The male cerci are subquadrate (almost rectangular) plate-like structures. This species has short wings and is incapable of flight, but is a very strong jumper.
Most similar to Melanoplus tumidicercus, but differs in the shape of the male cerci and the internal male genitalia. Other related species tend to differ in habitat and range.
Can be found in high quality riverine dune or sandhill communites of east Georgia. Inhabits low-growing limbs and brush, especially of oak (Quercus sp.).
Probably a generalist feeder on herbaceous plants and tender oak leaves. Often found in clumps of Gopher apple (Licania michauxii Prance).
Like all Orthopterans, the Melanoplus stegocercus undergoes an incomplete metamorphosis. Adults may be found throughout the growing season.
Walk through suitable habitat. Catch specimens with a net to confirm ID.
Endemic to the North American Coastal Plain of eastern 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 seven extant populantions are known. The populations are found on mix of private and public lands.
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.
