|scientific name Monochamus mutator |
common name Spotted Pine Sawyer
June to August (Linsley and Chemsak, 1984).
Moderate to large sized (17-27 mm) cerambycid with dark elytra with strong indentations. Hairs are white with bands running laterally on pronotum (Yanega, 1996). Antennae extending more than 5 segments past the elytra. Legs with faint white hairs. Distinguished from other Monochamus species by apices of elytra toothed and rounded (Linsley and Chemsak, 1984).
Similar to other Monochamus species. Adults emerge in June and feed on coniferous foliage and bark. Larvae will emerge and feed for 1-2 months, causing oval shaped excavation tunnels. If the tree is young enough, larvae can tunnel right through the tree (Ives and Wong, 1988).
Not of concern.
Larvae will feed on the sapwood and heartwood of numerous conifers (Yanega, 1996).
From Saskatchewan to New Brunswick (Bousquet, 1991).
