This’ll be the first in a new series of challenges focused on sign. What is “sign”, you might be asking? Generally, it’s something whose presence indicates the presence of something else. Here on this blog, of course, I’m referring to sign in nature. That could be tracks an animal left behind, scat or other droppings, a shed skin, feeding damage, and so on.
So, with that in mind, what is this sign and what critter does it reveal?
I highly recommend Tracks & Sign of Insects and Other Invertebrates. I find that it’s one of my most used references of late. If you already have it, you’ll find the answer to this challenge in it.
