Insidious Flower Bug (Nymph)
Orius insidiosus
- Order & Family
- Order Hemiptera; Family Anthocoridae
- Size
- 2mm to 2.5mm (adults); nymphs are smaller, often 1-2mm.
Natural Habitat
Gardens, agricultural fields, meadows, and areas with flowering plants.
Diet & Feeding
Omnivorous; primarily feeds on small insects like thrips, mites, aphids, and insect eggs, but occupies plants for pollen and nectar.
Behavior Patterns
Active hunters that use piercing-sucking mouthparts to drain prey. They undergo incomplete metamorphosis; nymphs resemble adults but lack wings. Known for occasionally biting humans if they land on skin.
Risks & Benefits
Highly beneficial to the ecosystem and farmers as a biological control agent for crop pests. Risks include a sharp, disproportionately painful 'pinch' or bite to humans, though they do not transmit diseases or feed on blood.
