Polyphagous predator feeding on thrips, mites, aphids, and insect eggs. It uses piercing-sucking mouthparts to drain fluids from its prey.
Behavior Patterns
Active hunters that undergo incomplete metamorphosis. They are known for 'nuisance biting' humans in late summer and fall as they seek moisture or check for food when searching for overwintering sites.
Risks & Benefits
Highly beneficial to the ecosystem and agriculture as a biological control agent for pests. They pose no medical risk to humans, though their bite can be surprisingly painful and cause temporary irritation or itchiness.
