Spiders that don't spin webs include tarantulas, wolf spiders, brown recluse spiders and trapdoor spiders. These spiders usually live in crevices or burrows. They produce silk but use it to line their burrows, make egg sacs or create trip lines for prey.
The tarantulas that are found in the American southwest usually live on the ground or in trees, but they also live in burrows like Aphonopelma chalcodes. They might not dig their own burrow but use one that's been vacated by another animal.
The Carolina wolf spider is considered the largest wolf spider in the United States, with females having a body that's about 0.9 to 1.4 inches long. Males are slightly smaller. It creates a burrow in open places that it lines with silk. The spider actively hunts or sits by the entrance and ambushes prey that comes by.
The brown recluse spider, which is one of two North American spiders whose venom is dangerous to humans, hides in dark places in human dwellings as well as crevices and under rocks.
Trapdoor spiders build funnels with lids. When they feel prey walking across the lid, they rush out, seize the prey, and drag it back into their lair.
