Dactylotum bicolor is a small, flightless grasshopper known for its striking aposematic coloration of black with red, yellow, and green markings. Native to shortgrass prairie and desert grasslands of western North America, it exhibits a complex life cycle with nymphs showing specialized feeding behavior on Wright's false willow (Baccharis wrightii) in parts of its range. The species demonstrates active thermoregulation through behavioral positioning relative to host plants and sunlight. Its bright warning coloration has been experimentally validated as effective aposematism against vertebrate predators.
