Natural Habitat

Found on flowers, foliage, tree bark, and sometimes venturing indoors near plants or windowsills.

Diet & Feeding

Carnivorous; they feed on insects such as flies, bees, butterflies, and beetles by ambushing them.

Behavior Patterns

They do not build webs; instead, they sit motionlessly on flowers or leaves, waiting to ambush prey using their long, crab-like front legs.

Risks & Benefits

They are beneficial to gardens and ecosystems as natural pest control agents, helping to manage insect populations. They are generally harmless to humans, though a defensive bite can cause minor local pain similar to a bee sting.
