Crab Spiders are from the family Thomisidae which consists of six sub families; Thomisinae, Bominae, Stiphropodinae, Stephanopinae, Strophiinae and Dietinae. Crab Spiders will live in and up trees, under bark, on or under rocks and stones, on flowers and leaves and on grass. Crab Spiders are great at ambushing their prey and don’t spin webs. They will sit patiently waiting for their prey to come to them and will then pounce on it. Their venom is potent to insects and it can kill a honey bee within seconds of the bee being bitten.
