Ischnopterapion virens (Herbst, 1797), new to Quebec

Species identification confirmed by RSA, 2016

Note.

Widely distributed through most of the Palaearctic region ( Alonso-Zarazaga 2011), this adventive species was recorded for the first time in North America in 1994, in Pennsylvania ( Hoebeke et al. 2000). Until now, it was known to occur in Canada only in the Maritime Provinces ( Bousquet et al. 2013). It is considered a pest of clovers, Trifolium L. spp. ( Fabaceae ). It can be distinguished from the superficially similar Stenopterapion meliloti Kirby, 1808, by its smaller size and the bluish colour of its pronotum and venter (black in S. meliloti ). As indicated by Hoebeke et al. (2000) and by the label data provided hereafter, the flight season extends until late in the year.
