Distribution in Canada and Alaska.

YT, BC, AB, NB ( Bousquet et al. 2013). These are the first eastern records of Dorytomus hirtus LeConte. Previously, this species was known as far east as AB in Canada and IN in the USA ( O’Brien 1970, Bousquet et al. 2013). This species will undoubtedly be found in the intervening areas and is likely transcontinental in Canada.

Comments.

In the western areas of its range, Dorytomus hirtus is associated with Populus fremonti S. Watson ( O’Brien 1970). In NB, this species was captured in Lindgren funnel traps in balsam poplar, Populus balsamifera L., the probable host in this region. All (15) specimens of Dorytomus hirtus were captured in Lindgren funnel traps in the canopy of Populus balsamifera , none in traps in the understory. Adults and larvae of this genus are associated with reproductive structures of various Salicaceae .
