oxhorndyvel

Onthophagus illyricus

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

The oxhorndyvel faces severe pressure from agricultural intensification across its Mediterranean range, particularly the widespread use of veterinary pharmaceuticals that contaminate dung and eliminate essential food sources. Habitat fragmentation from urban development and tourism infrastructure has isolated remaining populations, while climate change is shifting suitable habitat zones northward faster than the species can disperse.

Threat summary

Habitat

This dung beetle inhabits Mediterranean grasslands, oak woodlands, and pastoral landscapes where it depends on the dung of grazing mammals for breeding and feeding. It requires areas with traditional extensive grazing systems that maintain diverse microhabitats and seasonal dung availability.
