Summary
Prionus is a genus of long-horned beetles known for their large size and nocturnal habits. The larvae are important decomposers in forest ecosystems as they feed on rotting wood.
Physical Characteristics
Members of the genus Prionus are large (25–70 mm) and usually brown or black, with twelve or more strongly toothed or flabellate antennomeres on their large antennae.
Identification Tips
Look for robust bodies with long antennae; adults exhibit overlapping antennomeres and have apical segments often produced into lobes.
Habitat
Widespread in Europe, Asia, and North America, inhabiting areas with rotting wood or roots where their larvae can feed.
Distribution
22 species in 3 genera locally, 74 species in 9 genera across the New World; Prionus coriarius is found in England, while Prionus imbricornis, Prionus californicus, and Prionus laticollis are common in North America.
Diet
Larvae feed on rotting wood or roots; adults are attracted to light.
Life Cycle
The life cycle of Prionus species involves a larval stage that develops in decaying plant matter, indicating a typical wood-boring insect life cycle.
Ecosystem Role
As decomposers, they play a significant role in breaking down decaying wood and organic matter in their habitat.
Collecting Methods
- Light traps for adults at night
- Bark and wood sampling for larvae
Preservation Methods
