“What is this thing?” asks Kate, or as she asks us to call her, “Curious Kate in Colorado”. She refers to the big, white object pictured below. “I found it next to my front door! Should I move it? Let it be? It seems stuck, and this spot gets a lot of sun and gets very hot.” At first glance, we thought that this might be an egg sac of some kind – perhaps of some insect or species of spider. And it might be just that. That said, the size of it, as well as the fact that it is “stuck” on there (which we assume means that Kate had a hard time trying to pry it from the door frame) makes us wonder if it could be something else.
