nanonaturalist: nanonaturalist: My coworkers…



My coworkers bring me gifts; every bug they find in the hall ends up in a little cup on my desk. Today’s friend is a little caterpillar.

What would a caterpillar be doing in a building? Well, before they pupate, many moth caterpillars go through a wandering phase, where they leave their host plant (where a smart predator could easily find them), and wander around until they find a spot where they think, “Yes. This is it. My destiny.” Then they start chewing stuff up, spinning a cocoon (if they like), maybe burying themselves underground, then pupate.

I gave this baby a little piece of napkin, and they immediately started chewing it up to make silk to spin a cocoon. Cocoon spinning has been happening all day and we are making great progress!

Baby’s under the blankie!
