Caterpillar Rescue – Dagger in Distress!


Saturday, September 19, 2020. San Juan Island, WA – Caterpillar rescue!

I found one of these several years ago (September 20, 2017 to be exact), so I recognized it immediately when I saw it squirming in the spider webbing along the house this morning. My husband said I should just leave it alone. “Nature is ugly sometimes and you can’t interfere.” Well, when it was still there four hours later, suspended mid air, and still squirming, my tendency to SAVE things kicked in. The spider living above that web was actually dead. I’m not feeling very guilty about stealing food from a dead spider.

I got a cup and gently pulled at the web and began the process of freeing this caterpillar. It took finding my reading glasses and getting some fine-pointed tools to gently ply away the sticky bonds and clean the strands off the caterpillar hairs.

I think it looks pretty good! I even picked it some dinner and we’ll see if I can keep it healthy through pupation and adulthood.
