Phyllobius virideaeris

This record describes Phyllobius virideaeris (species). Recorded family: Curculionidae. Recorded order: Coleoptera.

Identification and Appearance

Phyllobius virideaeris - Phyllobius virideaeris

Length 4 or 5 mm. A bright metallic green or bluish nettle weevil. Phyllobius virideaeris lacks the femur teeth found on the majority of UK Phyllobius species. It can be distinguished from the similar P. roboretanus by the gently sloping rear end and also by examining underside. P. roboretanus only has a thin covering of fine scales, with much of the underlying surface visible. In P. viridiaeris the underside is densely coated with round scales, the same as the upperside. Phyllobius virideaeris also appears rather later in the year. Phyllobius is a genus of broad-nosed weevils that are commonly found on low herbage and in trees during spring and summer. Most are covered in metallic green scales that give them a very attractive appearance. There are 9 species and most look similar but they can be separated by carefully comparing the range of features shown in the table below, either under a binocular microscope or with a x20 hand-lens. Phyllobius weevils can be distinguished from the similar genus Polydrusus by looking where the antennae emerge from the rostrum. In Phyllobius the antennae emerge from the top whilst in Polydrusus they are positioned at the side. When looking directly down on the beetle it is usually clear to see. Unless identified by a recognised expert, photographic evidence is required and the specimen should be examined with a microscope. In the comments box, state the key or ID method used. Note the beetle's size and describe the identifying characters. It is advisable to retain the specimen in case further checks are needed. May be found in rough grassland and on neighbouring bushes and hedges. The larvae are subterranean, feeding on a range of herbaceous roots. A common and widespread weevil occurring throughout England and Wales and with scattered records across southern Scotland.

About Primitive Winged Insects: the wider group

Order-level background for Coleoptera, the group containing Phyllobius virideaeris. 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.
