Common dung beetle

<em>Aphodius pedellus</em>, a species of dung beetle in the family Scarabaeidae, is classified as Least Concern by the IUCN Red List, indicating a stable conservation outlook across its known range. The species has been documented in Denmark, Norway, Sweden, Switzerland, and the United States, with its distribution spanning virtually all terrestrial and freshwater biome types. As a member of the Aphodiini tribe, <em>Aphodius pedellus</em> typically inhabits pastures, meadows, and woodland edges where mammalian dung is available, as dung beetles in this genus rely on feces as both a breeding medium and a food resource. These beetles play a critical role in nutrient cycling and soil aeration, breaking down organic waste and accelerating the return of nutrients to the soil. Their burrowing activity beneath dung pats enhances soil structure and improves water infiltration. <em>Aphodius pedellus</em> is part of a guild of coprophagous insects that collectively support healthy agricultural and natural ecosystems across temperate Europe and North America. Biological traits of this species remain poorly documented in the scientific literature.
