Red-tipped Crab Spider

Sidymella rubrosignata

"Sidymella rubrosignata" is a species of crab spiders found in Australia. It is a common spider, often seen on "Dianella" plants. Like all thomisid spiders, it does not make a web, but lies in wait for prey to appear nearby. Their prey is insects, or occasionally other small spiders.

Appearance

Often these spiders are a well camouflaged green, making their presence difficult to discern on green leaves or flowers. Occasionally they may be yellow, light brown or reddish. Males are 4.5 mm long, female 8 mm. Males are slimmer and smaller.

The front two pairs of legs are much longer than the other two pairs of legs. The abdomen is trapezium shaped, with a pair of dorsal humps, with a red patch on each of them. The cephalothorax is pear-shaped.
