scientific name    Buprestis langi    

habitat
Conifer forests of the boreal, montane and subalpine regions.

seasonality
In Alberta, adults are known from July 2 through September 3.

identification
Males tend to be brilliant green, sometimes with coppery over tones, with large yellow paired spots (2, 4 or 6) on their elytra. Females differ in usually lacking spots, or with a pair of small spots on their brilliant green elytra. The beetles are of moderate size with females ranging from 13 to 19 mm. with a mean of 15.5 mm (n=21) and males 14.5 to 15.0 mm (n=2)

life history
Little is known of their life history. Females are seldom found in association with the males. They are frequently captured while trying to oviposit on logs. Males, rarely collected, may be found on the foliage of willow, alders and poplars near where the females are ovipositing. The sister species B. fasciata (Fabricius) is reported breeding in maple and poplar. It is interesting to speculate that there has been a host shift with B. langi in that development is now in conifers but the mating sites are still associated with hardwoods. Prolonged larval development has been reported for this species with emergence from flooring, siding and pilings.

conservation
Widespread, or locally common with the potential of causing major damage to cut trees and lumber.

diet info
Larvae have been reported in Douglas Fir. Other hosts are ponderosa pine, lodgepole pine and white spruce.. In Alberta adult females are often associated with lodgepole pine.

range
The species is found from Mexico north to central B.C. in the mountains with populations in the boreal forest of Manitoba and Saskatchewan. Alberta records are primarily in the foothill and mountain forests (lodgepole pine zone).
