This moth was laying eggs on the wall of my house in Oakland, CA. She was about 1″ long.
Your moth is a common Southern California Tiger Moth known as a Painted Arachnis. We had eight individuals on our screen door and near our porch light on Mt Washington in Los Angeles this past week. One female also laid eggs. Over the years, we have observed these moths laying eggs on our walls numerous times. The caterpillars are general feeders of the Woolly Bear type.
