Common Names: Flower crab spiders
This is a catch-all for crab spiders in the Thomisidae family, many of which can be challenging to ID on photo alone. Among the Thomisidae, 'crab spider' refers most often to the familiar species of 'lower crab spiders', though not all members of the family are limited to ambush hunting in flowers. Thomisidae do not build webs to trap prey, though all of them produce silk for drop lines and sundry reproductive purposes; some are wandering hunters and the most widely known are ambush predators. Some species sit on or beside flowers or fruit, where they grab visiting insects.
