Carnegie Museum of Natural History’s Section of Invertebrate Zoology had a moth eclose earlier this month.  The little caterpillar came in on the oak leaves that staff were feeding to other caterpillar cultures. It was identified as a one-spotted variant (Hypagyrtis unipunctata), a very common moth in the Geometridae subfamily Ennominae.

The pictures show its progress from an early instar caterpillar to an adult moth.
