The Ranchman's Tiger Moth (Pyrrharctia isabella) is very common in the west.

It is one of the more colorful moths with polka dots on the outer wings. It also has yellow and black on the inner wings/body.

The catepillars are well known as the wooly bear.

The name tiger moth fits a group of moths (Arctiinae), that generally share the characteristi of having a striped body. It's not shown in the picture, however, the Ranchman's Tiger Moth's body is striped.

They are found in the Northwestern part of the United States, mostly west of the Rocky mountains.
