- I found this burrow in a nature strip on my road. I've seen a large black spider at the entrance with its front legs sticking out, obviously it backs down quickly whenever I get too close but if I shine a torch down the hole I can still see it. You can see its front legs in the pic. Im not sure if it's a funnel web or a trap door spider. If it is a funnel web, do I need to tell someone or just leave it be?
