Buprestis aurulenta (Buprestidae)

the golden Buprestid


Buprestis aurulenta, the golden buprestid, adult beetles. Family characteristics + particular features - brilliant metallic green with red line along outer and inner margins of elytra; bronze colour below. Surface "sculpturing" of elytra characterized by wide spaces separated by narrow ridges.


Buprestis aurulenta, the golden buprestid, larvae. Family characteristics of flatheaded borers: flattened in cross-section; thorax broad, with plates above and below; legs absent. Require 1-3 years to complete development. In buildings, egg to adult development may be prolonged to 30, 40, even 50 years.


Buprestis aurulenta larval galleries in sapwood. Adults lay eggs on bark. Larval galleries score the sapwood. Later larval instars bore into the sapwood where they complete their development. Grubholes flattened, upper and lower surfaces parallel, packed with frass. Exit holes elliptical.

Principal Hosts:

Douglas-fir and ponderosa pine.

Economic Importance:

This species is the most damaging in its genus. Larvae have been known to take 30 years to complete their development in structural timbers. The emergence holes sometimes penetrate roofing materials which results in leakages. The Orpheum Theater in Vancouver was water damaged after "bargain priced" roofing timbers, cut from trees salvaged from the Taylor River fire on Vancouver Island, produced a large number of adult beetles which bored straight through the tar roof.
