From what I understand, you can identify four spider types based on their web. Funnel-shaped webs are naturally built by Funnel Web spiders (Agelenidae). Orb spiders (Araneidae) make the "typical" kind of web with spokes coming out from the center. "Tangled" webs are usually in very secluded corners (Theridiidae). Sheet webs are strung in between plant stalks by Linyphiinae.
