Other: D. carolina is a large grasshopper
that is typically found in open areas with sand and gravel (such as gravel
pits, railway beds and roads). It is easily identified by
its characteristic black wings with yellow rims. The body color ranges from tan to
dark brown to black and is dependent on the coloration of the substrate that
the grasshopper lived on during its development. The adults fly well
and can hover above the ground. Their flight is similar to a
butterfly's in its fluttery wavering nature. Females are larger then the
males. There is one generation per year. Population explosions
of this grasshopper are partially controlled by the fungus
Entomophaga grylli. Economically the
Black-winged Grasshopper is not a significant pest, causing minor damage to
tobacco, cereals, grasses and alfalfa crops. (Vickery and Kevan, 1985) |
