A friend brought in some ready potted Asian Lilies to put in a border at the front of the house. Unfortunately whoever the grower was has a phytosanitary problem and now she has imported a nuisance pest.
Immediately the colour was the giveaway and unmistakable, red for danger! On only six small plants there were ten Lily beetles wandering. All that could be done was to knock them off and use a heavy foot.
Lily beetle also known as the Scarlet Lily beetle.
A close eye will have to be kept on all the lilies in the garden to make sure there is no spread from these pests that can cause quite a lot of damage to Lilies and Fritillaries.
Organic methods of control come down to regularly inspecting the plants and picking off the beetles. See the RHS information
here if you want more methods.
