Both my lavender plants have several flower stems that look like they're being eaten by something:
The stems eventually get so weak they fall over.
Most of the stems are about a foot tall (the plants are new this year) and the damage occurs a few inches below the flower buds. I'm guessing it's an insect, but I can't see any likely candidates, and I'm not finding many references to lavender pests.
Anyone know what it is?
