Lecontia
conifer bark beetles
Lecontia is a genus of conifer bark beetles in the family Boridae, containing a single species, Lecontia discicollis. These beetles are found in Central America and North America, where they inhabit the bark of dead conifers. The genus is notable for its specialized association with fire-killed or stressed conifer trees, particularly in the years following forest fires.
Lecontia discicollis
Burnt Conifer Bark Beetle
Lecontia discicollis is a distinctive conifer bark beetle in the family Boridae, the sole member of its genus in North America. It is a slow-moving, jet black beetle with a convex, bullet-like shape and bead-like antennae. The species is strongly associated with fire-killed conifers, particularly ponderosa pine, where adults and larvae occupy a narrow ecological niche in moist, white-rotted wood near and below ground level. Despite being locally common in suitable habitat, it is rarely encountered due to its specialized requirements.
Melanophila occidentalis
Melanophila occidentalis is a metallic wood-boring beetle in the family Buprestidae, described by Obenberger in 1928. The genus Melanophila is notable for its pyrophilic behavior, with some species attracted to smoke and heat from forest fires. This species occurs in North America, including British Columbia, Canada. Like other members of the genus, it likely develops in fire-scarred or recently burned coniferous wood.
Sericoda
Sericoda is a genus of harpaline ground beetles native to the Holarctic region, with apparent North American origin. These beetles are pyrophilous, meaning they are strongly attracted to burned areas following forest fires. They are generally smaller than related genera such as Agonum. Two species, Sericoda quadripunctata and S. bembidioides, have been extensively studied in boreal forests of Alberta, Canada, where they serve as hosts for phoretic mites of the genus Antennoseius.
Upis ceramboides
Roughened Darkling Beetle, kökskörven
Upis ceramboides is a fire-dependent darkling beetle that colonizes burned deciduous trees, particularly birch. The species has declined in southern Sweden due to fire suppression and modern forestry, persisting mainly in northern Scandinavia, Alaska, and Canada. Adults exhibit extreme freeze tolerance, surviving temperatures well below freezing through unique biochemical adaptations including xylomannan antifreeze and threitol. Larvae develop in fire-damaged inner bark rich in fungal mycelia, with a two-to-three-year life cycle.
