Tree trunk spiders belong to the Family Hersiliidae. There are about 150 species in this family and many more undiscovered. ve spider and thus is most unlikely to cause significant harm. Female Tree Spiders are around 19mm in body length from its chelicerae to the tip of its spinnerets. When her legs stretched out, its longest legs can reach 45mm. They range in size from about 10 mm (0.4 inch) to 18 mm (0.7 inch)long including the "Tails". Tree spiders are beautiful with multicolor pattern that helps them in camouflaging against the tree trunks they live on. Being very well camouflaged for life on the varicolored trunks of trees, they have an interesting way of capturing prey. Rather than making a web that captures prey directly, they lay a light coating of threads over an area of tree bark and wait hidden in plain sight for an insect to stray onto that patch. Once that occurs, they direct their spinnerets toward their prey and circle it all the while casting silk on it. When the hapless insect has been thoroughly immobilized they can bite it through its new shroud.
