Came across this centimetre long insect in mid-autumn along a dirt road beside a forested area. It really stood out for such a small creature.

This is a Crowned Slug Caterpillar, Isa textula. According to BugGuide: “Larvae are often found on oak, but also eat leaves of many other trees including cherry, maple, basswood, elm and beech.” This caterpillar should be handled with care as it is capable of stinging.
