Biology: The biology and gallery system were described by Beaver (1984). The species is polyphagous, and nearly always breeds in old, dry twigs from 0.7–3.0 cm diameter. The gallery system consists of a radial gallery, and usually two longitudinal branches running up and down the stem. The eggs are laid in separate niches, but the larvae develop and feed on the ambrosia fungus growing in the parental gallery. As in the Xyleborini, only one or two males are produced in each gallery. They are smaller than the females, and are presumed to mate with their sisters in the parental gallery.
