Geotrupinae

Geotrupinae occupy diverse habitats including temperate and tropical forests, grasslands, montane regions, and arid areas. In Mexico, they occur in high mountain volcanic massifs (2800-3400 m elevation) of the Trans-Mexican Volcanic Belt, showing maximal abundance at middle altitudes on windward (humid) slopes. The tribe Athyreini is associated with tropical areas at 50-1400 m elevation, Bolboceratini with arid areas from sea level to 1700 m, and Geotrupini across various conditions at 1500-3200 m. Australian species occur across diverse habitats including arid and temperate regions.

Global distribution with concentration in temperate and tropical regions. North America: documented across the United States and southern Canada, with detailed records from Great Smoky Mountains National Park. Mexico: widespread in the Trans-Mexican Volcanic Belt including La Malinche, Cofre de Perote, Pico de Orizaba, and Sierra Negra volcanoes; also in Chiapas (central depression and various municipalities); Hidalgo state along altitudinal transects. Central America: Costa Rica, with Neoathyreus species. Australia: endemic radiation with multiple endemic genera including Blackburnium, Bolbobaineus, Australobolbus, Blackbolbus, and Bolboleaus.

Adult activity varies by region. In Mexican high mountains, sampling conducted during rainy season (June-August) yielded specimens. In Great Smoky Mountains National Park, seasonality patterns documented but specific months not detailed in available sources. Australian Stenaspidius species exhibit day-flying behavior. Many species attracted to ultraviolet and fluorescent light, indicating nocturnal activity patterns.

Coprophagous (dung-feeding) behavior documented across multiple species. Adults feed on mammal dung, fungi, and decaying organic matter; larvae develop in soil burrows provisioned with dung, leaf litter, or other organic material. Some species show flexibility in food choice, utilizing fresh grass clippings or other plant material for larval development.

Complete metamorphosis with egg, larva, pupa, and adult stages. Larvae develop in burrows excavated by adults, provisioned with organic material (dung, leaf litter, or fungi). Pupation occurs within the burrow. Specific developmental durations vary by species and environmental conditions.

Primarily nocturnal; adults frequently attracted to fluorescent light, public lighting, and ultraviolet light sources. Burrowing behavior: adults excavate soil burrows for shelter and larval provisioning. Some species exhibit day-flying behavior (e.g., Stenaspidius in Australia). Horizontal colonization patterns observed on volcanic massifs, with mountain-affiliated species dispersing along mountain chains or the Altiplano.

Important decomposers in terrestrial ecosystems, contributing to nutrient cycling through dung burial and decomposition. Facilitate soil aeration through burrowing activities. Serve as indicators of ecosystem health and habitat quality in montane and other environments. Component of diverse dung beetle assemblages alongside Scarabaeinae and Aphodiinae.

Ecological indicators for conservation and land management decisions. Some species associated with agroecosystems and cattle production environments. Taxonomic interest due to high regional endemism, particularly in Australia and Mexico. Subject of biogeographic and ecological research in transition zones and mountain systems.
