I’m back in Newfoundland for a vacation, and while mowing the lawn came across a bunch of baby spiders in a nest, that looked something like this:

It was quite a windy day, but when I crouched down to look at them, even the slightest breeze from my own breath caused them to disperse out from their tight bunch, much like these spiders are doing:

Being biocurious, I have been wondering, what’s the difference between a breeze and my own breath that the baby spiders ignore the former and run at the feel of the latter?
