Species Guides

1

Campylomorphus is a of click beetles (Elateridae) containing a single , Campylomorphus homalisinus. The genus is characterized by its rare orophilous (mountain-dwelling) habit and discontinuous distribution across southwestern Europe. are small, flower-foraging beetles with feeding strategies. The genus exhibits a fragmented geographic pattern hypothesized to reflect Pleistocene glaciation dynamics.

Habitat

in this inhabit montane environments including shrublands, grasslands, and forests. In Italy, occur in montane grassland formations at elevations of 400–1900 m, with western populations tending toward higher altitudes than eastern populations. Associated vegetation includes Sorbus aucuparia, Rosa species, Genista tinctoria, Genista radiata, Vaccinium uliginosum, and Vaccinium myrtillus. Substrates include limestone and marl.

Distribution

Discontinuous distribution across the Iberian Peninsula, France (primarily Mercantour National Park), and Italy. Italian records span the Northern Apennines from Liguria through Tuscany to Umbria and Marche, including provinces of Cuneo, Imperia, Savona, Genova, La Spezia, Pavia, Piacenza, Parma, Reggio nell'Emilia, Modena, Bologna, Lucca, Massa-Carrara, Pistoia, Firenze, Forlì-Cesena, Arezzo, Pesaro-Urbino, and Perugia. Altitudinal range extends to 50 m in the Iberian Peninsula but is restricted to higher elevations (400–1900 m) in Italy and France.

Diet

integrate flower resources into their diet according to a strategy. Has been observed feeding on nectar of Laserpitium siler (Apiaceae). The generalist approach allows utilization of flowers with diverse morphologies, including disc-shaped white flowers with accessible nectar in umbrella-shaped blooms.

Host Associations

  • Laserpitium siler - nectar sourceApiaceae; observed flower-foraging site

Life Cycle

Larval stages and habits remain unknown. No data available on development or larval requirements.

Behavior

exhibit flower-foraging , traveling between flower patches in patterns associated with resource uptake. Females are rarely recorded in collections (9 females out of 96 specimens examined), suggesting they may live hidden and emerge infrequently.

Ecological Role

Flower visitor and potential . As part of the Elateridae , contributes to pollination services in montane .
