Goes tigrinus (DeGeer)
Orig. Comb: Cerambyx tigrinus DeGeer 1775
Covered in reticulated snow white pubescence. Plectrodera scalator (a close relative in the tribe Monochamini) is similar but the black bands are thicker, more distinct, shiny, and occurring in a totally different pattern. Sometimes the white oak borer has a very faint bluish grey tint, but only rarely to the extent shown in Yanega's figure (340)
Widespread, but uncommon in e US (TX-FL-NY-MI) (3)
(Linsley & Chemsak 1984)
May-Oct, but most abundant June-July (3)
Larvae feed in living hardwoods, especially oak, Quercus (3)
Adults emerge in mid-spring and deposit eggs in roughened bark or near wounds. About 3 weeks later, eggs hatch, and larvae tunnel directly into the wood. New adults develop within the tunnels and emerge through a new, circular exit hole. The life cycle requires 3 to 5 years for completion.
Very uncommonly collected although widespead and reportedly an important pest of all oaks in the white oak group.
