salt marsh moth (Estigmene acres) on Jun 22, 2023

Submitter has sample

Description of specimen

I believe it’s a white ermine moth native to Eurasia. I’ve spent 25 years in Oregon and never seen one like this.

Commentary

Thank you for your report! That is our native salt marsh moth, Estigmene acrea. Its larva is the yellow woolly bear caterpillar that is much more familiar than the adults, which fly at night.
