True weevils 2
The True weevils 2 RES Handbook covers the subfamily Ceutorhynchinae. It features illustrated identification keys for tribes, genera and species.
Species notes include characters for distinguishing the sexes, plus information on biology, larval food plants, distribution within Britain and Ireland and geographic range. The author has also indicated which species have current ‘Red Data Book’ or ‘Notable’ status.
True weevils (family Curculionidae) are a huge group of beetle species, many of which are common and widespread. They occur in a wide range of terrestrial and freshwater habitats. Many weevils possess a rostrum, clubbed antennae and a bilobed 3rd tarsomere. Overall there are around 500 species of true weevil in the UK.
The Ceutorhynchinae is one of the largest UK subfamilies. As a group these weevils are straightforward to distinguish, as the rostrum is generally twice as long as wide. All species feed on plants, both as larvae and adults, with a wide range of host plants. A small number of species are agricultural pests, particularly of brassica crops. Very few are arboreal and none feed on dead wood.
Handbooks for the Identification of British Insects is a series of books produced by the Royal Entomological Society (RES). Each Handbook provides illustrated identification keys to the insects of Britain, together with concise morphological, biological and distributional information. Accordingly all books contain line drawings, and the most recent volumes feature colour photographs. RES Handbooks are suitable for experienced users. The series also includes several Check Lists of British Insects. Field Studies Council has published RES Handbooks for many years. Many out-of-print Handbooks are now available for free download from the RES.
