Abstract

Adults and larvae of Rhinosimus viridiaeneus Randall observed on Vancouver Island, British Columbia, prefer the inner bark of dead branches of red alder (Alnus rubra Bong.) for food. When feeding, the flattened elongated rostrum of the adult is inserted between the papery outer bark and the cambium. The rostrum is also used to prod or flip intruding Rhinosimus away from a feeding site. The larva is described for the first time.

Résumé

Les adultes et les larves de Rhinosimus viridiaeneus Randall observés sur l’Ile de Vancouver en Colombie Britannique, préfèrent l’écorce interne des branches mortes de l’aulne rouge (Alnus rubra Bong.) comme nourriture. Lors de l’alimentation, le rostre allongé et aplati de l’adulte est inséré entre l’écorce externe et le cambium. Le rostre est aussi utilisé pour repousser ou déloger tout Rhinosimus intrus d’un site d’alimentation. La larve est décrite pour la première fois.
