How can I stop the red beetles eating my lilies?

In recent years the lily beetle has spread throughout the country. The bright red beetles overwinter in the soil, emerging from late March through to June and start to feed on the leaves and stems of lilies and fritillaries. Over a period of time the female lays 200-300 eggs. The larvae hatch about 10 days after the eggs were laid and feed on the the plants for approximately a month before going to the soil to spin a cocoon where they pupate. As some adult beetles do not emerge until June adults, eggs and larvae can be present throughout late spring and summer.

Any adults that are seen on the plants can be removed and destroyed. Insecticides are available from garden centres and DIY stores for the control of the lily beetle.
