The lily leaf beetle Lilioceris lilii is a serious pest of cultivated lilies in gardens and an emerging pest of native lilies in the wild.  The beetle was introduced from Europe and was first noticed in Montreal  in the 1940s.  Since then, it has been spreading throughout the northeastern US and eastern Canada, and pockets of infestation have been recorded as far west as Alberta.  

The main reason for this site is to gather information on the beetle’s distribution as it spreads throughout North America.  If you have lily beetles in your garden, or if you have seen them on native lilies or even on other plants, please let us know by using the simple form on the “Report an Infestation” page.  This will allow us to create an updated distribution map for the beetle.

As well, the site will offer basic information about the lily leaf beetle.  I’ll also be posting information about biological control using parasitic wasps.  These tiny wasps are non-stinging and will only attack lily leaf beetle.  Over the course of the field season, I’ll be blogging regularly about our research on biocontrol in Ottawa, Ontario, Canada, as well as observations and results from other projects involving the beetle.
