If you’re lucky and you know what to look for, you can watch mini wildlife documentaries unfolding in front of you. Back in late May I was lucky to witness mesh-web weavers courting and mating; I’m writing it up (including photos and video) because I couldn’t easily find anything else online about this intriguing behaviour.
Most wild animals are either indifferent or fearful towards humans, preferring to run away when they realize a human has noticed them — or attack when they cannot escape. Spiders are no different in this regard. Many of them are too short-sighted, or live on too small a scale, to recognize humans as other animals and not, say, unusually mobile parts of the landscape. If they do, they deduce that we are neither food nor fellow spiders (for spiders, generally antisocial creatures, these overlap considerably), and they try to get out of our way.
