Field Identification
Large, slow-moving flightless grasshoppers of the southeastern United States that gather in open sunny areas and strip vegetation. Bright warning coloration signals toxicity to many predators.
Adults are 2–3 inches long, yellow-orange with black pattern (color morphs vary). Nymphs are black with yellow or red stripes.
How to Deal With It
Organic Control Methods
Reduce weedy margins preferred for egg-laying; rotate disturbance of known egg beds in fall.
Natural enemies include birds, mammals, and parasitic flies; chemical defenses limit insect predators but do not stop all mortality.
On small sites, concentrate effort when nymphs are localized in black bands.
Hand-pick or stomp (gloves recommended); knock into buckets of soapy water. Fence valuable beds with smooth metal or fine mesh extending above hop height.
Sprays are marginally effective on adults; target young nymphs with spinosad or neem on ornamental or food gardens per label, accepting that large adults may need physical removal.
