Omphalapion hookerorum (Kirby, 1808), new to Quebec

Species identification confirmed by RSA, 2015

Note.

This Palaearctic adventive species was recorded for the first time in North America in 1993 based on specimens collected in Nova Scotia in 1990 (Peschken 1993 and Sampson and MacSween 1993, in Majka et al. 2007b). In Canada, it was subsequently released and is established as a biological control agent against scentless chamomile, Tripleurospermum inodorum (L.) Sch.Bip. (= Matricaria perforata Mérat) ( Asteraceae ) in British Columbia, Alberta, Saskatchewan, and Manitoba ( McClay and De Clerck-Floate 1999). It was also collected on stinking chamomile, Anthemis cotula L. ( Asteraceae ), in Nova Scotia ( Majka et al. 2007b).
