Order & Family: Order: Trombidiformes; Family: Anystidae
Size: Typically 1.0 mm to 1.5 mm in diameter, usually visible to the naked eye as a moving red speck.
Natural Habitat
Found worldwide in diverse environments including gardens, woodlands, grasslands, and frequently on man-made structures like walls, patios, and sidewalks.
Diet & Feeding
Predatory generalist. They feed on small arthropods like aphids, thrips, spider mites, leafhoppers, and small insect larvae.
Behavior Patterns
Known for their chaotic, erratic, and incredibly fast movement. They run in spiral or figure-eight patterns (hence 'whirligig'). They are active hunters rather than web-builders.
Risks & Benefits
Benefits: Highly beneficial for pest control in gardens and agriculture as they consume plant-damaging insects. Risks: Harmless to humans and pets; they do not bite, sting, or damage household items, though their red color can inadvertently stain fabric if crushed.
