Identify this caterpillar

Asked March 24, 2019, 2:30 PM EDT

HI,
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.

Douglas County Colorado

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

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
Thanks.

I agree!
