NOVA SCOTIA: 18 specimens were examined from Annapolis, Colchester, Cumberland, Digby, Guysborough, Halifax, Kings, Queens, and Victoria counties. The earliest record is from 1965 (Cumberland Co.: Wentworth, 21.v–5.vii.1965, B. Wright, NSMC).

Newly recorded in New Brunswick. Members of the Melandryini are xylophagous (Pollock 2002).

In Québec, it has been beaten from dead branches of Quercus rubra . (D. Pollock, unpublished data).
