Trichius sexualis
Local name: Keleti prémesbogár
The Keleti prémesbogár (Trichius sexualis) is a distinctive flower chafer beetle characterized by its robust, hairy body and metallic bronze-green coloration with yellowish markings. Adults are commonly observed feeding on flower nectar and pollen, particularly favoring umbelliferous plants, while their larvae develop in decaying organic matter and compost-rich soils, playing an important role in nutrient cycling.

Species Profile
The Keleti prémesbogár (Trichius sexualis) is a distinctive flower chafer beetle characterized by its robust, hairy body and metallic bronze-green coloration with yellowish markings. Adults are commonly observed feeding on flower nectar and pollen, particularly favoring umbelliferous plants, while their larvae develop in decaying organic matter and compost-rich soils, playing an important role in nutrient cycling.
Trichius sexualis faces severe population declines primarily due to habitat loss from agricultural intensification and urbanization in its limited Central European range. The species' specialized requirements for old-growth deciduous forests with specific host plants make it particularly vulnerable to landscape fragmentation and changes in forest management practices.
Key Facts
Habitat & Distribution
Trichius sexualis inhabits flower-rich grasslands, meadow edges, and traditional agricultural landscapes with abundant hedgerows and unmown areas. The species requires proximity to decaying organic matter such as compost heaps, rotting logs, or leaf litter where larvae can complete their development.
Threats
