Banded Alder Borer

Along a woodland trail, on 23 July 2020 at the Nisqually wildlife Refuge just east of Olympia, Erika and I found a Banded Alder Borer, Rosalia funebris. Actually we discovered this longhorn beetle because two other visitors were taking pictures of it. These beetles are found from Alaska to California and New Mexico, often on alder tree bark. These insects are not thought of as pests, since their larvae generally bore into downed wood. The adults usually feed on flowers (Wikipedia).
