Epiptera opaca (Say) ranges from Quebec south to Georgia and west to Ontario and Mississippi; it has also been recorded from British Columbia (Beirne 1950, Wilson and McPherson 1980). This achilid has been associated with pines (Hepburn 1967); otherwise no information on the biology of this species is available. Based on observations of E. fusca (Walker), Hepburn (1967) noted that the immature stages of all species of Epiptera probably live beneath the loose bark of dead trees, presumably feeding on fungal hyphae.
