Sericoda quadripunctata

(DeGeer, 1774)

Four-spotted Sericoda

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

Identification

Distinguished from by association with post-fire ; S. bembidioides is sympatric but shows opposite response to forest harvesting (lower catches where S. quadripunctata shows higher catches). Specific morphological diagnostic features not available from sources.

Images

Habitat

Recently burned forests in regions; post-fire sites. Abundance positively associated with fire severity.

Distribution

Holarctic: Europe, Northern Asia (excluding China), North America. Documented in Alberta (Canada), Alaska (USA), Austria, Belgium, and Bhutan.

Seasonality

Most abundant in first post-fire year; abundance decreases drastically by third post-fire year.

Host Associations

  • Antennoseius perseus - phoretic mite inhabits space under described from specimens collected from this in Alberta, Canada
  • Antennoseius pyrophilus - phoretic mite inhabits space under described from specimens collected from this in Alberta, Canada; epithet reflects fire association

Life Cycle

Abundance pattern indicates early successional specialization; peaks immediately post-fire and declines within three years.

Behavior

Pyrophilous (fire-adapted); exhibits strong attraction to recently burned . Serves as phoretic for mites, which use the for to new burn sites.

Ecological Role

Bioindicator of post-fire ecological conditions and salvage logging impacts; presence and abundance reflect fire severity and early successional stage of forest .

Human Relevance

Used as study organism for assessing ecological impacts of salvage logging (post-fire removal of burned trees); higher catches in areas with combined wildfire and forest harvesting compared to wildfire alone.

Similar Taxa

  • Sericoda bembidioidesSympatric with opposite response to forest harvesting (lower catches where S. quadripunctata increases); both are pyrophilous but differ in management sensitivity.
