Common Red Soldier Beetle (Rhagonycha fulva) lives in open grasslands across Europe and Asia. It feeds on aphids and pollen.
Fascinating facts about the Common Red Soldier Beetle
- At just 8-10 millimetres long, the common red soldier beetle flashes a bold dark-red wing cover that ends in a stark black spot. Its orange head and pronotum shine, while the antennae stay black, sometimes with an orange first segment. The femora and tibiae stay orange, contrasting with black tarsi whose third segment is simple, not bilobed.
- Adult beetles from June to August, feeding on aphids, pollen and nectar, while their larvae lurk at grass bases preying on slugs and snails. This dual diet means the species supports plant reproduction as a pollinator. Their short, busy summer lives packed with feeding and mating illustrate how a single insect can bridge predator-prey and plant-pollinator roles in a single season.
- Often seen perched on open-structured flowers like cow-parsley and hogweed, the beetle becomes a key pollinator for two hogweed species: Heracleum sphondylium and H. mantegazzianum. By moving from bloom to bloom, it transfers pollen while hunting aphids. This mutualism highlights the beetle's ecological importance beyond its cute appearance, showing how insect visitors sustain both wild and invasive plant populations.
- First named in 1763, this beetle's scientific story began when Giovanni Antonio Scopoli recorded it as Cantharis fulva in his work Entomologia Carniolica.
- Native to Europe and Anatolia, the beetle has hopped across the Atlantic, now thriving in British Columbia, Quebec and, more recently, Ontario.
