Silkworms, Day 56 - Silkmoths!

There she is! (At least I think it's a she from the books. . .) I woke up this morning and found this little moth sitting in the cocoon box. So cute! But a lot smaller than I thought she'd be. Most of the photos are so zoomed in and blown up, I thought she'd be bigger.

I looked up about that red liquid you can see in the foreground. Silkmoth pee. She also squirted some sort of tan liquid on me when I picked her up to move her off the cocoon and onto a paper roll. Don't know if that was more pee, or the pheromones I've read about, but it sure came out in a violent jet!

I've decided this these are the biggest and smallest cocoons in our set. I'm still amazed with how different they are in size, but almost all the others are just a little smaller than the big one. These are really the unusual ones.

As I was searching for the big and small cocoons, a second moth emerged. Here you can compare how they look fresh out of the cocoon, with their little smooshed, wet wings, compared to the one that had been out for hours already.

As a sort of sad follow up to the last silkworm post, one of those two straggler caterpillars died later that day. The other finally started spinning his cocoon, but didn't complete it. I suspect he's dead inside the partial cocoon he started, but I haven't been motivated to investigate inside it to make sure.

This whole thing is most fascinating!

Ours haven't emerged yet.
