Ant Crab Spider
Scientific Name: Synema globosum

Diet & Feeding
Strictly carnivorous, feeding on a wide variety of insects, especially pollinators visiting flowers, such as bees, flies, and other small insects.
Behavior Patterns
These spiders are ambush predators. They do not build webs for catching prey but instead wait camouflaged on flowers or leaves, striking rapidly when an unsuspecting insect comes within reach. They are known for their ability to change color slowly (over several days) to match their surroundings, aiding in camouflage.
