Arhopalus foveicollis    




habitat
Coniferous forests of North America east of the Rocky Mountains (Yanega 1996).

seasonality
Adult flight period is June though August (Yanega 1996).

identification
Body robust, dark brown to blackish, dull. Head closely punctuate, antennae to apical 1/3 of elytra, with segments 8-11 as long as the preceding 3 together. Gula with a dense beard of long pale hairs, pronotum distinctly wider than long, sides usually rounded, rarely angular. Abdomen with 5th sternite truncate or feebly emarginated at apex. Females more robust than males, abdomen with 5th sternite rounded at the apex (Linsley 1962). Eyes not hairy, pronotal surface irregular with a pair of deep pits; elytra with distinct ridges. The range extends westward to overlap with that of a similar species A. asparatus (LeConte), which is possibly only a variant of A. foveicollis (Yanega 1996; Linsley 1962). Overall, A. foveicollis is most defined by their nicely rounded pair of pronotal pits, rounded pronotal profile and gradually abbreviated antennal segments.

Breeds in Pinus and Picea (Downie and Arnett 1996).
