White Crab Spider
Scientific Name: Misumena vatia
Order & Family: Araneae, Thomisidae
Size: Females typically 8-10 mm; males 3-4 mm.

Natural Habitat
Gardens, meadows, fields, and other floral environments where they can ambush prey. They often sit on flowers camouflaged to match their surroundings.
Diet & Feeding
Predatory. They primarily feed on various insects, including bees, flies, butterflies, and other pollinators, which they ambush on flowers.
Behavior Patterns
These spiders are ambush predators that do not build webs for catching prey. Instead, they sit on flowers and wait for insects to come to them. They are well-known for their ability to change color (within a few days) between white and yellow to match the flowers they are hunting on, providing excellent camouflage.
Risks & Benefits
Generally beneficial to ecosystems as they help control insect populations. They pose no significant risk to humans; their venom is not considered medically significant, and they rarely bite. Their color-changing ability and predatory habits make them interesting subjects for ecological studies.
