At the ARC-PPRI Spider Centre we undertake systematic research on the spider family Thomisidae. The thomisids, also known as crabspiders, are commonly found on plants where they excel as ambushers. Their gait is sideways or crab-like, hence their common name. Although they have weak fangs they secrete potent venom that enables them to attack prey 2-3 times their own size. They are very commonly found on crops and play an important role as natural enemy of various pest species in agro-ecosystems.
