FAMILY HERSILIIDAE - Two-tailed Spiders

Spiders in this family are small spider and easily identified. They have two tails, actually they are the long spinnerets. Two-tailed Spider sits on tree trunk and lay silk on the near by area. When a small insect come close, the insect triggers those silk and the spider senses this. The spider will quickly run around the insect in circles, with the insect in center. The spider will also lay more silk at the same time, until the insect entangled by the silk, becomes the meal of the spider.
