@snowywinter: Most spiders are able to snare their prey into their webs. However, there is a certain spider that has a different way of catching its meal. This spider is called the trap-door spider. This spider lives in the deserts of Mexico and the western United States.
These spiders spend most of their time in a ground tunnel that it has dug and then covered with what is known as a “trap door” made of pebbles and sand. This door is attached to the ground on one side, somewhat like a hinged door, and is so precisely built that creatures above the ground can’t even see it.
However, the spider knows where its trap door is. It can easily move through it and into its tunnels if it feels impending danger.
The trap-door spider has excellent hearing. It can hear an insect walking on the ground close to the trap door. When an insect walks near the trap door, the spider pops out of its hole and snatches the insect up. It drops back down into its tunnel and closes the door behind it.
