The Banded Alder Borer (Rosalia funebris) is a member of the very diverse family of longhorn beetles.

Like many other species in the family Cerambycidae, R. funebris has strikingly colored wing covers (elytra).

They are found in western North America, from Alaska through California, and in New Mexico.

[2] The adult wood-boring beetles lay their eggs in a crevice in the bark of hardwood trees, such as Oregon ash, New Mexico willow, and California laurel/Oregon myrtle.

[2] When handled or threatened R. funebris makes an audible noise similar to that of a squeaky running shoe, or a hissing sound much like air being let out of a bike tire.
