We spotted this Scarlet Lily Beetle on a favourite LIly in our garden this weekend (25th July). It looks lovely but it is an alien species from Central Europe that feeds on Lilies. If you see one get rid of it and it;s eggs or larvae. The eggs are orange and about 1 mm long, laid on the underside of the LIly leaves. It also goes on other members of the LIly family. The adult beetle is bright scarlet and about 1 cm. long.
