Pallid-Winged Grasshopper

Fascinating facts about the Pallid-Winged Grasshopper

• The pallid-winged grasshopper lives in desert habitats that stretch from British Columbia in Canada down through the western United States and Mexico to Argentina in South America, making it a common species across this vast range. It prefers the dry river-bed gravel and granite surfaces where its pale, mottled colour provides camouflage. During the hot summer months the insects are most active, taking advantage of the open, sun-baked terrain.
• Temperature governs the daily routine of the pallid-winged grasshopper. When the air warms to between 24 °C and 32 °C the insects leave their perches to forage for plant material, timing their feeding to the midday heat. A higher thermal window of 30 °C to 40 °C triggers mating behaviour, prompting males to seek females and perform their aerial displays.
• Male pallid-winged grasshoppers launch flights that snap their wings, creating a crackling noise known as crepitation. The sound is produced when the insects are disturbed or during courtship.
• During courtship a male pallid-winged grasshopper rubs the hind femur against the forewing, producing a clear trilling sound. This stridulation is paired with the crackling noise created when the wings snap during a crepitation flight. The wing-snap sound is emitted either when the insect is disturbed or as part of the same courtship display, giving females both auditory and visual cues.
• Populations of the pallid-winged grasshopper sometimes surge to damaging levels, known as irruptions. Between 1952 and 1980 Arizona recorded six outbreaks, only one of which lasted more than one year.
