|scientific name Dicerca hesperoborealis |
Similar in appearance to beetles of D. tenebrica. Adults of hesperoborealis tend to be more "brassy" in colour than those of tenebrica. The grooved medial carina of the anticoxal plate of hesperoborealis will separate the species.
In Alberta the beetles has been reared from paper birch. The larval cycle is expected to last at least 2 years (Ives and Wong, 1988).
Uncommon, but likely wide spread.
This species has been reared from birch in Alberta.
