Giant Grassland Cicada (Tibicen dorsatus)
22 July 09; There are a number of species in this genus. They are collectively referred to as the "dog-day cicadas" as many reach their peak abundance during late summer (the dog-days of summer). This species is one of the more widespread and numerous on Fort SIll this time of year. And they can be deafening. Unlike many early season cicadas, these species often are kicked up in tall grasses and perch about eye-level in small shrubs or low oaks when disturbed from the grasses.
