Summary

Geotrupes is a genus of earth-boring scarab beetles known for their ecological role in soil ecosystems, aiding in the decomposition process. They exhibit various colors and physical characteristics, making identification reliant on subtle morphological features.

Physical Characteristics

Generally black or blue, with varying colors from bright green to black; pronotum usually has some obvious punctures laterally and may be dull granulate.

Identification Tips

1. Elytra with striae obsolete, showing rows of punctures; dull granulate black. 2. Elytra with striae impunctate. 3. Very convex shape, elytra different colors. 4. Sutural striae ending at scutellum. 5. Elytra with sutural striae complete to base; may show hints of blue or green in certain species.

Habitat

Holarctic regions, found in various habitats across North America, particularly east of the Rockies.

Distribution

Found from Canada to Mexico, specifically east of the Rockies.

Diet

Primarily detritivores, feeding on decomposing organic matter.

Life Cycle

Details on the specific life cycle of Geotrupes species are not provided, but typically include egg, larval, pupal, and adult stages.

Reproduction

Geotrupes species generally reproduce through laying eggs in the soil, which develop into larvae that feed on organic material.

Ecosystem Role

As detritivores, these beetles play a crucial role in soil aeration and the decomposition of organic matter.

Collecting Methods

  • Pitfall traps
  • Hand collection during daytime.
  • Light traps at night.

Preservation Methods

  • Ethanol preservation for molecular studies
  • Pinned specimens for taxonomic collections.

Evolution

Evolutionary adaptations allow Geotrupes species to thrive in various environments, mainly focusing on their role in the ecosystem as decomposers.

Misconceptions

Some may confuse Geotrupes with other beetles due to their color variations; they are primarily distinguished by elytral striae.
