Banded Alder Borer
Dear anon125
This beautiful creature is known as a Banded Alder Borer or California Laurel Borer, Rosalia funebris, and BugGuide indicates is is found in the: “Western United States plus British Columbia and Alaska.” The larvae are Flatheaded Borers in dead hardwood trees including maple, alder, oak, willow and other hardwoods according to BugGuide, and Charles Hogue in his book Insects of the Los Angeles basin also adds ash and eucalyptus. The Banded Alder Borer is not considered to be a harmful species. The Washington State University Cooperative Extension webpage written by entomologist Arthur L. Antonelli adds: “The adults usually are encountered singly in summer, but occasionally they are attracted in numbers to fresh paint.” Hogue made a similar comment. A European relative known as the Blue Rosalia, Rosalia alpina, is considered an endangered species and it has been featured on the postage stamps of several European countries including this beautiful example of a German stamp from 1993. We don’t believe the Banded Alder Borer has ever appeared on a stamp.
