See this bug in the Encyclopedia

Natural Habitat

Commonly found in lush lawns, turfgrass, and on building foundations, window sills, and masonry walls.

Diet & Feeding

Herbivorous; they feed on the sap of over 200 plant species, primarily grasses and clover.

Behavior Patterns

They are most active during the spring and fall. They exhibit a unique behavior of invading homes in large numbers when their outdoor environment becomes unfavorable, often crawling up walls and through window cracks.

Risks & Benefits

They do not bite humans or pets and do not transmit diseases. Their primary risk is aesthetic; if crushed, they leave a red stain (not blood, but pigments from their body) on fabrics, carpets, or walls. They are generally considered a nuisance pest rather than a threat.
