The Painted Grasshopper (Dactylotum bicolor) is one of the most colorful grasshopper species in North America. It is easily recognized by its vivid red, yellow, and black coloration and is sometimes referred to as the “rainbow grasshopper.”
Taxonomy and Classification
This species belongs to the family Acrididae, which includes many of the common short-horned grasshoppers.

- Genus: Dactylotum
- Species: Dactylotum bicolor
Physical Description
- Length: 20–35 mm
- Coloration: Bright patterns of red, yellow, and black
- Wings: Often shortened, limiting long-distance flight
- Body: Thick and robust
Distribution and Habitat
Painted grasshoppers are primarily found in the western United States and parts of northern Mexico.

Behavior and Damage
Unlike some agricultural grasshopper pests, this species rarely reaches population levels capable of causing serious crop damage. Individuals feed on a variety of plants and grasses.
Management and Prevention
Large populations may occasionally damage vegetation. Maintaining healthy vegetation and encouraging natural predators such as birds can help keep populations balanced.
Conservation and Research
The striking coloration of painted grasshoppers is thought to function as warning coloration that discourages predators.
