Collection and habitat data.
In New Brunswick, Mordellina pustulata adults were swept from foliage along a river margin, in a regenerating (20-year-old) mixed forest, and along a power-line right-of-way through a mixed forest. Adults were also swept from flowers of bristly sarsaparilla ( Aralia hispida Vent.) in a small old field within a regenerating (20-year-old) mixed forest. This species was collected during late June and July. Elsewhere, Mordellina pustulata has been reared from stems of Gentiana andrewsii Griseb. (Gentianaceae), Veronia altissima Nutt. ( Scrophulariaceae), and 19 species of Asteraceae (Ford and Jackman 1996; Lisberg and Young 2003).
