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.

Sericoda quadripunctata
Four-spotted Sericoda
Sericoda quadripunctata is a pyrophilous ground beetle strongly associated with recently burned forests in boreal regions. Its abundance peaks in the first year after wildfire and declines sharply by the third post-fire year. The species serves as a phoretic host for specialized mites (Antennoseius perseus and A. pyrophilus) that inhabit the space beneath its elytra. It occurs across the Holarctic region, including Europe, Northern Asia, and North America.

Tetropium parvulum
Northern Spruce Borer
Tetropium parvulum, the northern spruce borer, is a small cerambycid beetle specialized on spruce hosts. It was elevated from synonymy with T. cinnamopterum based on distinct morphological differences in larvae and adults, and exhibits strict host specificity to Picea compared to the conifer generalist T. cinnamopterum. The species has a one-year life cycle and is an economically important borer of white and Engelmann spruce logs in western Canada.
