Bright red with a black head, a Lily Leaf Beetle can decimate all kinds of lilies, and it is on the move.

Found in North America in the mid 1900's, the Lily Leaf Beetle is a pest that requires diligent control. The scarlet red beetle has a black head and black belly. If squeezed, it squeaks audibly. Females lay small red or brown eggs in irregular rows under lily leaves. Once the larva hatches, it gets to work, chewing up the entire leaf and moving onto other parts of the plant when that food is exhausted. The small grub covers itself in its own feces as protection, making it look like brown crud on the edges of a leaf it is eating from. Native lilies are at risk from the extensive feeding of this hungry larva. All varieties of true lilies can be attacked as well as Fritillaria, but daylilies do not seem to interest it.

Controlling the population is paramount to reducing the damage done by the beetle. Immediately removing adults by tapping the branch so they fall into soapy water is easier than trying to catch one running for cover. Removing and soaking affected leaves can kill small grubs hiding under feces. Daily examinations of lily plants are necessary to limit the beetle's damage. So far, the beetle has a range that includes eastern Canadian provinces and New England States, but that range is expanding. Beetles may hide in containers and the popularity of lilies means they are likely to spread farther if left unchecked. Recognizing and eliminating the beetle is necessary to keep plants healthy and alive.

* MAP NOTES: The territorial heat map above showcases (in red) the states and territories of North America where the Lily Leaf Beetle may be found (but is not limited to). This sort of data is useful when attempting to see concentrations of particular species across the continent as well as revealing possible migratory patterns over a species' given lifespan. Some insects are naturally confined by environment, weather, mating habits, food resources and the like while others see widespread expansion across most, or all, of North America. States/Territories shown above are a general indicator of areas inhabited by the Lily Leaf Beetle. Insects generally go where they please, typically driven by diet, environmental changes, and / or mating habits.
