White crab spider
Thomisus sp. (likely Thomisus spectabilis)
- Order & Family
- Araneae, Thomisidae (crab spiders)
- Size
- Typically 4–10 mm in body length; females are substantially larger than males.
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.
