Title: Lily Leaf Beetle Biological Control Update

Publisher: University of Maine

Resource Type: Fact sheet

Description: Lilies (“true lilies”, plants of the genus Lilium) are an important source of color in summer and early fall perennial gardens. However in recent years, home and commercial gardeners have been plagued by a bright red beetle whose feeding causes extensive damage to many susceptible lily species and hybrids. This very serious pest is the lily leaf beetle (LLB), Lilioceris lilii. LLB, a native insect of Europe, has become a widespread pest of native and exotic lilies throughout New England, where it was first reported in 1997. This beetle threatens the use of garden lilies in our region.
