Eudolus quadriguttatus
Local name: fyrfläckig dyngbagge
The fyrfläckig dyngbagge (Eudolus quadriguttatus) is a distinctive click beetle characterized by four yellowish spots on its dark elytra, giving it its Swedish name meaning 'four-spotted dung beetle.' This species plays an important ecological role as a decomposer, with larvae developing in decaying organic matter and adults contributing to nutrient cycling in forest ecosystems.

Species Profile
The fyrfläckig dyngbagge (Eudolus quadriguttatus) is a distinctive click beetle characterized by four yellowish spots on its dark elytra, giving it its Swedish name meaning 'four-spotted dung beetle.' This species plays an important ecological role as a decomposer, with larvae developing in decaying organic matter and adults contributing to nutrient cycling in forest ecosystems.
The fyrfläckig dyngbagge (Eudolus quadriguttatus) is declining primarily due to habitat loss from agricultural intensification and changes in livestock management practices. The species depends on traditional pastoral systems with grazing animals that produce the dung necessary for its life cycle, but modern farming methods have reduced the availability of suitable breeding substrates.
Key Facts
Habitat & Distribution
Eudolus quadriguttatus inhabits mature coniferous and mixed forests with abundant dead wood, particularly favoring areas with decaying logs, stumps, and woody debris on the forest floor. The species requires stable microhabitats with consistent moisture levels and fungal activity that support larval development.
Threats
