Dear Leif, thank you for contacting us re the larva of the Sphingidae moth. This is Hyles lineata, the white-lined Sphinx moth, a native moth throughout the Pacific Northwest. It is very common throughout the year. Here is more info: http://pnwmoths.biol.wwu.edu/browse/family-sphingidae/subfamily-macroglossinae/hyles/hyles-lineata/
Thank you, Helmuth Rogg
