(The word of the day is a random word on a random page of the Torre-Bueno Glossary of Entomology)

Synanthropic, associated with and living with man, in his dwellings, other building, or produce.

This word  refers to non-domesticated creatures such cockroaches, house flies, larder beetles, etc… things that are cosmopolitan pests, well adapted to living alongside humans in their homes and food storage.

I guess you could say the caterpillars we rear in the lab are synanthropic against their will.
