It is known as the Signature Spider because of this. The spider holds its legs together in pairs, making it look like a creature with four legs instead of eight.
Crab spiders catch their prey by ambush.
They lie in wait on flowers, often aided by camouflage, for nectar-feeding insects. Like this brush-footed butterfly Phalanta phalantha , these insects may be much larger than the spider but they are soon paralysed with a venomous bite. Unlike web-weaving spiders which ensnare flying insects in their nets or crab spiders which ambush their prey, jumping spiders actively hunt for food. The Spiny-backed Spider has projections which curve over its back like a pair of horns. It is also known as the Horned Spider.
