Identify this caterpillar

Asked March 24, 2019, 2:30 PM EDT

Can you identify this caterpillar? It reminds me of a forest tent caterpillar (Malacosoma sp) but does not have actual "blue lines" on the sides. More like blue blotches.

Does look somewhat like a tent-what plant is it on? That would help with the ID.

We have done more research and believe it is a Police Car Moth caterpillar. The moth scientific is Gnophaela vermiculata. What's your opinion. The caterpillar was found on Mertensia ciliata

I agree!
I found a source from Western Washington University.
