Banded Alder Borer The banded alder borer, Rosalia funebris Motschulsky, is a member of the beetle family known as Cerambycidae. This family is known collectively as the long horned wood boring beetles. The banded alder borer is the only species of this genus in North America, occurring from Alaska to southern California and in the Rocky Mountains from Idaho to New Mexico. The larvae bore in the trunks of dead Acer, Alnus, Fraxinus, Platanus, Quercus, Salix, and Umbellularia californica, but are not recorded as economically damaging. The adults (Fig. 1) are elongate, flattened, parallel-sided beetles about 25 to 35 mm long. The body and long antennae are conspicuously blackand-white banded. The adults usually are encountered singly in summer, but occasionally they are attracted in numbers to fresh paint. The banded alder borer is not a pest and there is no need for control. The adults are sometimes mistaken for the imported Asian long-horned beetle. The latter, however, has white spots on a shiny black background—not bands! Fig. 1. Adult banded alder borer.
