Insects of Cedar Creek
Order ORTHOPTERA
(Grasshoppers, etc.)
The Orthoptera (1082 NA spp) are abundantly and diversely represented at Cedar Creek. Most conspicuous are the Short-horned Grasshoppers (Acrididae). The Slant-faced Grasshoppers (Acridinae) are grass feeders. The Banded-wing Grasshoppers (Oedipodinae) are mixed feeders primarily in xeric fields. The most abundant group are the Spur-throats (Melanoplinae and Cyrtacanthacridinae) which are primarily forb feeders. The Tettigoniidae (Long-horned Meadow Grasshoppers) are also quite abundant and signal the arrival of fall with their various calls. The Gryllidae (Ground Crickets, Bush Crickets), are also common. Families of lesser abundance include the Tetrigidae (Pygmy Grasshoppers), the Gryllotalpidae and Tridactylidae (Mole Crickets), and the Gryllacrididae (Camel Crickets).
