Crab Spider Bite

Crab Spider

A crab spider bite may be poisonous but not poisonous enough to harm humans. The crab spider uses its bite to hunt for food and kill its prey prior to sucking it dry.

Crab spiders are abundant in a wide area range of Australia and are usually found in bushes, seeding heads of grasses and in flowers as well. The color of the crab spider usually is based on the color of the hunting terrain, providing them with a camouflaging feature effective in food hunting and protection for predators.There are large species of crab spiders but all species are not dangerous to humans.

Sizes of crab spiders range from 4 mm to 12mm. They can be easily recognized since when teased expand their legs and move sideways like a crab.

Venom

The potent venom of the crab spider bite is enough to quickly paralyze or immobilize its prey such as when bees land on flowers. The crab spider bite is initiated by their chelicerae or jaws which are small and slender.

The crab spider is a patient hunter. It remains on a single location even for weeks when hunting for prey. Crab spiders not only eat bees but they also kill flies, mosquitoes, moth and other insect pests, making them beneficial to humans.

Symptoms

The poisonous bite of a crab spider is not dangerous to human beings but can still hurt a lot. The crab spider bite on a human can provide an excruciating pain just like a hammer blow on your finger nails. The cut of a crab spider bite may grow to double its size. If bitten on the nails, the finger of the victim may be discolored while the pain brought about by the bite may reach the hand. The bite symptoms subsides after a few hours.
