  Diamond-Bellied Crab Spider
Angaeus rhombifer Thorell 1890
close-up of brownish crab spider Female
Crab spiders move sideways, like crabs. The body is not as hairy as in most spiders. Classification: Family Thomisidae, Crab Spiders
Habitat: Grasses, low shrubs and tree trunks in wooded areas.
Female: 9 mm.
Distribution: Singapore, Indonesia, Myanmar.
They are slow-moving spiders which do not actively hunt like Wolf Spiders. Instead, they remain stationary and await in ambush for some unsuspecting insects to land in front of them. The first two pairs of legs in most Crab Spiders are longer and heavier than the third and fourth pairs, and are armed with spines for holding and grasping prey.
