Lily beetle in a garden near you
See also Have you seen Lily Beetle this year
Andrew Halstead (1989) summarised the history of the species in Britain as well as giving horticultural tips. The beetle, which is widespread in Europe and North Africa was only sporadically reported in this country from the nineteenth century until 1940 when it seems to have established at Chobham, Surrey. Subsequently it spread through the whole of Surrey into Berkshire, Buckinghamshire and adjacent areas.
Mike Cox (CABI Bioscience, Department of Entomology, The Natural History Museum, London SW7 5BD) is studying the spread of the species and would welcome records of its occurrence either in your garden or elsewhere in the country, or you can submit records here.
