Red lily leaf beetle, Lilioceris lilii
The red lily leaf beetle is newest pest to arrive in Washington. It was found in Bellevue, WA this spring by WSDA. This beetle will create problems for hobby lily growers, gardeners, and commercial producers and purveyors of cut flowers. Hosts include Lilium spp. (true lilies, especially Asiatic lilies.), Fritillaria spp. (fritillaries), Polygonatum (Solomon’s seal), Solanum (nightshades and potato), Smilax spp. and Nicotianaspp. Early detection will limit damage and possibly limit the spread of this beautiful little insect. Damage includes: feeding along leaf margins by the red adults, and skeletonizing of the leaves by black larvae. Larvae are covered by their excrement – a very effective deterrent to predators as they look like a bit of soot. Tiny red eggs are laid in clusters on the hosts listed. Please e-mail email@example.com if you find this pest. While there is not likely to be any regulatory action, we ourselves can reduce the spread of pests by quick personal local action and news sharing.
