Geotrupidae
Geotrupidae is a family of beetles commonly known as earth-boring dung beetles or dor beetles. Members of this family are notable for their ecological roles and distinctive behaviors.
Key Characteristics:
Geotrupidae beetles are robust, usually dark-colored, and range in size from medium to large.
Many species are associated with decaying organic matter, dung, or fungi, which they use as food sources and for nesting.
Adults are strong diggers, using their powerful legs to excavate tunnels in the soil.
Ecological Role:
These beetles play an important part in nutrient cycling by burying dung and decaying material, which enriches the soil and aids in decomposition.
Their tunneling activity helps aerate the soil.
Behavior:
Most Geotrupidae species are nocturnal.
They typically dig burrows beneath dung or decaying vegetation, where they lay their eggs.
Some species are known for making a characteristic buzzing sound during flight.
Distribution:
Geotrupidae are found worldwide, with the greatest diversity in temperate regions.
Notable Genera:
Geotrupes (the type genus)
Trypocopris
Anoplotrupes
Distinction from Other Dung Beetles:
Unlike scarab dung beetles (family Scarabaeidae), Geotrupidae generally dig straight vertical tunnels rather than rolling dung balls.
