|scientific name Buprestis lyrata |
Conifer forests, usually containing Douglas fir or pines.
In general, these beetles are larger, in Alberta averaging 19.25 mm.(n= 13, 16-23 mm) Beetles are black without dorsal maculations, ventrally the last 1 to 3 abdominal sternites have lateral orange spots. A few immaculate B. nutalli may be confused with this species. Size and presence of maculation on all abdominal sternites will separate the species.
Little is known.
Relatively uncommon. However, in the foothills they may be locally common on fresh Douglas fir logs.
In B.C. B. lyrata is known from ponderosa pine and Douglas Fir. In Alberta the beetles have been associated with Douglas Fir logs. In the east neither of these tree species are present, which implies the use of another host, probably jack pine.
The beetles are reported to occur from B.C. east to Nova Scotia in the boreal forest, and south through the mountain regions of western United States. In Alberta the specimens that I have seen all come from the montane forests, with Douglas Fir. Bright (1987) shows records from the Peace river area and in Saskatchewan around east of Cold Lake.
