Notes on RDB species: All these weevils (with the exception of O. beuthini, a fairly recent discovery in England) have declined markedly during the past half-century and are very poorly known. However, all either feed on field-margin plants or have been recorded specifically from cereal fields (P. lemoroi).

Notes on Notable species: The issue of cereal field margins is a complex one. Many other Notable species might be added to the list above. Priority has been given to species feeding on particularly transient 'weed' species. D. angulosus also occurs on disturbed peatlands.
