These are excellent garden and yard dwelling spiders that will live in rocks or between groups of leaves. they make somewhat triangular webs with web covered funnels that usually go into a crack or behind leaves. the triangular webbing is used to catch prey and the funnel is used for hiding and waiting. when an unfortunate bug ends up in the web, the funnel spider races out, grabs the bug, and takes it back into the funnel (sometimes they just race out, bite the bug, and leave it there for later). over the course of a summer-fall season these spiders molt a few times leaving behind their former exoskeletons and sometimes their webs too. some can grow to be quite large with massive webs, but don't worry, these spiders seem to prefer the outdoors and if you leave them alone they leave you alone.
