Data characterizing alternative overwintering strategies of the alder bark beetle

Abstract

This dataset describes two distinct overwintering strategies of the alder bark beetle, Alniphagus aspericollis, in red alder, Alnus rubra. These data were used to evaluate the fitness trade-offs associated with either overwintering strategy: overwintering as mature larvae in the main stems (i.e., boles) of host trees, or as adult beetles within branch nodes. Data were collected from four sites in southwestern British Columbia, Canada.
