Caterpillar identification question.

Asked April 18, 2019, 5:45 PM EDT

One of my students saw several of these caterpillars at Graham Oaks Nature Reserve in Wilsonville. Is it just a Wooly Bear with opposite coloring? I tried a variety of sources to figure it out. Thank you, Jay Schauer

Your student has stumped me, too. However, I’ve requested assistance from an entomologist and will get back to you after I receive his response.


The answer just arrived.

It’s a ranchman’s tiger moth caterpillar, Platyprepia virginalis. Here is a link to bugguide with information about the species…

The entomologist said he finds the caterpillars quite often in the spring at a local wetland down in Corvallis.
