Funnel weaver

Spider of the ageliniidae family. Agelenids build a flat sheet of nonsticky web with a funnel-shaped. They await the arrival of prey falling onto the horizontal web. Although the web is not sticky, it is full of entangling filaments and they catch in the insect's body or limbs. The spider reacts immediately to vibrations and attack the prey by rushing out at high speed and dealing a paralysing venomous bite. They are very fast spiders. Usually harmless to humans except in one case, the bite of the hobo spider (Eratigena agrestis) may be medically significant, and some evidence suggests it might cause necrotic lesions.
