Asiatic lily leaf beetle. THEY ARE AWFUL!! AND THEY "SCREAM" WHEN YOU PUT A LITTLE PRESSURE ON THEM...CREEPIEST THING EVER!!

It's an invasive species, I never had them until last year and they ate all my Asiatics last year. Nothing bloomed! They have reemerged this year so thankfully the beetles didnt permanently kill them.

These beetles mate like crazy (I never find just one, always two with one on top of the other), and leave a red/brown/black/pink glob of eggs on the leaves. It's actually the little devil-spawn that do the most damage. I was behind the ball last year, but I've tried to get ahead of it this year by checking the lillies everyday (real thorough check! those beetles hide in the tight spaces between the leaves by the stem) and plucking the beetles off and then stomping them (from the girl that wont even kill slugs or pillbugs, but instead re-homes them, the fact that I opt for death says a lot about them).

The eggs hatch after a few days or so, feed on the lilies, then burrow into the ground where they morph into the beetles..then they come up and eat more.

You've got to check the leaves everyday trying to find the egg-slime. I read that the best way to ensure the eggs are killed is to take the entire leaf off the lily and drop it in soapy water..but all my lilies would be leafless so I'm attempting to wipe it off and then get them in the soapy water.

I also read that Neem Oil works well while not being harmful to anything else. Because of the amount of lilies I have it would cost me a fortune, so I'm crossing my fingers that vigilance will pay off. So far, so good. By the time my lilies had gotten to this size last year they were already turning brown and withering, and had barely a leaf on them.....but they've stayed nice and green so far this year so seems to be working.

SO: Stay vigilant about searching & destroying (kill those screaming monsters; if you don't they'll come right back), and don't forget to check for and remove the eggs!

Good luck!
