Bruchus rufimanus
This record describes Bruchus rufimanus (species). Recorded family: Chrysomelidae. Recorded order: Coleoptera.
Identification and Appearance
Sometimes known as the Broad Bean Weevil (or Broad Bean Beetle). At 3.5-5 mm, this is the largest species in the genus Bruchus . The elytra are grey-brown, flecked with white, and are shorter than the body. The antennae are orange at the base, and whilst the front legs are reddish, the middle legs are black. The pronotum has a relatively dense covering of scale-like hairs. Bruchus atomarius is generally smaller (2.5-3.5mm),has a similar body pattern and leg colour but the pronotum only has sparse hairs. State the size. Images should show the hairs on the pronotum, the dorsal pattern and the leg colour. Anywhere that the larval foodplants can be found, and a pest of Broad Bean crops. Particularly fond of Broad Beans but also other members of the Vicia family. The Bruchid beetle larvae tunnel into the developing bean seeds within the pod and the subsequent exit holes can cause sufficient damage which can lead to crop rejection. Widespread in England but fewer records from elsewhere in Britain.

About Primitive Winged Insects: the wider group
Order-level background for Coleoptera, the group containing Bruchus rufimanus. Species-specific details appear above.
Group overview
Coleoptera is the largest order of insects with over 400,000 described species, representing ~25% of all known animal species and ~40% of all insects. In the U.S. alone, nearly 30,000 beetle species have been identified.
Ecological role of the group
Beetles are prominent decomposers, especially in forests, breaking down dead wood and recycling nutrients. As predators, they reduce populations of pest insects. Many species are also important pollinators of flowering plants.
Economic and practical significance of the group
Beetles have major economic significance: leaf beetles (Chrysomelidae) and weevils (Curculionoidea) are among the most destructive agricultural pests globally, costing billions annually, while predatory species like ladybugs provide natural pest control.
Recorded sources for this group: Britannica, Smithsonian, NCSU Entomology. Imported estimates may describe particular regions or reporting periods.
