Mecaphesa celer
swift crab spider
Mecaphesa celer is a crab spider in the family Thomisidae, commonly known as the swift crab spider. It is distributed across much of North and Central America. The species exhibits extreme sexual size dimorphism, with females more than twice the size of males. It is a sit-and-wait predator that hunts on flowers and upper plant parts, and has been studied for its population genetics in fragmented volcanic habitats.
