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.

Crowned Slug Caterpillar

Hi Bonnie,
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.
