Keep your eyes peeled for lily beetle
Help the RHS track red lily beetle progress, which are active again this month, by reporting sightings on rhs.org.uk/ science/help-ourresearch/lily-beetle The beetles will eat fritillaries as well as lilies, and can quickly ruin a display. Adult beetles can be picked off plants by hand, while pesticides are likely to be more effective on larvae (which will become most prevalent in the next few weeks). Heavy infestations can be treated with pesticides, such as Westland Resolva Bug Killer or Bayer Sprayday Greenfly Killer. Organic insecticides containing natural pyrethrins may also have some effect. Plants in flower should not be sprayed due to the danger to pollinating insects.
