Nip your lily leaf beetle problem in the bud, or in the egg, by squishing this pest’s red, shiny ova before they hatch. Here’s what they look like… laid in a line, on the underside of lily leaves.
Oriental and Asiatic lilies are particularly yummy to the lily leaf beetle, and the three successive generations of these bugs per summer can denude a lily as quickly as that.
No leaves, then no food production to feed the bulb. Soon, no bulb.
In my garden, 2009 was the worst invasion yet of these pretty, but voracious, red beetles. For info on safe control of the adults and larvae (fingers may be involved), see my posts from June and August of last year, here and here. But the best defense is at the egg stage, when they’ll hold still long enough for the Flying Squishing Fingers of Fate to do their business. Get to it.
