Natural Habitat

Gardens, meadows, and areas with flowering plants. They are often found on flowers where they ambush prey.

Diet & Feeding

Strictly carnivorous, preying on various insects that visit flowers, such as bees, flies, butterflies, and other pollinators.

Behavior Patterns

Crab spiders are ambush predators. They do not build webs for catching prey but instead rely on camouflage, often changing their body color to match the flower they are sitting on. They wait motionless for prey to come within striking distance.

Risks & Benefits

Crab spiders are generally harmless to humans. Their venom is potent enough for their insect prey but not considered medically significant for people. They are beneficial in gardens as they help control populations of various insects.
