Whip Spider (Ariamnes flagellum)
Ariamnes is a genus of comb-footed spiders (family Theridiidae). They have greatly elongated abdomens, making them resemble a twig.
Like many species in its genus, Ariamnes flagellum has an extremely elongated abdomen, resembling a twig or pine needle. The abdomen can be bent upwards.
They are green in colour and they are often found resting on one or two threads of silk. It eats wandering spiders, mostly juveniles (and some insects). The whip spider waits above the few strands of silk of its snare. When a small wandering spider hits the silk, this causes the whip spider to descend. The whip spider uses the "comb foot" of its end segment of the last pair of legs to wrap the meal in silk.
