Natural Habitat

Flowers, foliage, and garden vegetation, especially in warm, sunlit habitats. This individual is positioned on a white flower, where it can ambush visiting insects.

Diet & Feeding

Predatory; it ambushes bees, flies, butterflies, and other flower-visiting insects without using a web to capture them.

Behavior Patterns

It holds its enlarged front legs sideways like a crab and may change color gradually to match its flower. Females guard egg sacs briefly, while spiderlings disperse by ballooning or crawling.

Risks & Benefits

Not dangerous to people; its bite is rare and generally medically insignificant. It benefits gardens by reducing pollinating and plant-feeding insect populations, though it may also capture bees.
