Otiorhynchus armadillo

This record describes Otiorhynchus armadillo (species). Recorded family: Curculionidae. Recorded order: Coleoptera.

Identification and Appearance

Otiorhynchus armadillo - Otiorhynchus armadillo

A very distinct weevil, the females reaching 15mm in length, it is similar to the more common Vine weevil ( Otiorhynchus sulcatus ), but O. armadillo has a broader body shape, and no tooth on the front femur. Unless identified by a recognised expert, good photos are required that show the key ID features. Also state the beetle's size in the comments box. A pest of plants in parks and gardens. Hosts include Spindle tree leaves, Rosaceae plants, Ivy, Cherry Laurel, Ornamental Willow and Viburnum. Although it is capable of surviving cold conditions, it is most likely to me observed during the warmer months of the year. The species seems to be mainly nocturnal and the larvae feed on various plant roots whilst the adults feed on the leaves. Mainly recorded from the southern half of Britain, but may be spreading. Believed to have been accidentally imported from the Mediterranean and regarded as among the most serious garden pests in Europe. In South West London where they were first discovered in 1998 the species is now reaching pest proportions and it has officially become the most common weevil there.

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Otiorhynchus armadillo. 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.
