Swarms of spiders escape New South Wales floods (video)

Spiders of NSW, Australia swarm to higher ground to escape flooding

I have never seen this before. It’s an interesting reminder that insects as well as people make a positive effort to go to higher ground to escape flooding. In this instance it almost seems that the spiders are on a par with humans in the way they are committed to finding a way to avoid drowning. We normally don’t pay any attention at all to insects during flooding and yet here they are in their swarms struggling to get to higher ground, to survive.

Insect respiration takes place by passive diffusion into and out of a network of tracheal tubes. They have ‘book lungs’. They are vulnerable to drowning.

Shenae and Steve Varley witnessed spiders covering ‘the entire length of the railing that is not under water at the Penrith Weir in western Sydney (YouTube video seen below):

Videos from YouTube have a tendency of disappearing over time which means they stop working! Sorry if that has happened but I can’t control it.

Here are 2 Facebook posts from Matt Lovenfosse:

They are only a couple meters off the back fence now.
