  Scorpion Spider
Arachnura sp.
close-up of female imitating a dry twig
The abdomen is armed anteriorly with two horns and posteriorly with a peculiar star-shaped tip. Tries to enhance its imitation of a dry twig by folding its legs and drawing them close to the body.
Classification: Family Araneidae, Orb-Web Spiders.
Habitat: Inside primary forests.
Female: 12-15 mm.
When alarmed, the posterior end of the abdomen is curled upwards, scorpion-style.

The web is a widely-spaced orb with a missing sector, usually slung in a horizontal or inclined plane.
