I looked that up, and I think you're right! Sure looks the same. Thanks, Su! I didn't want to kill them right away, because I thought they might be a good witch. But now I see they're a bad witch, so they get the death sentence. I've never seen them before. I suspect they may have come in on the dirt in the pot of the celery plant I bought.
Do you think I should pull up the celery?
This is from the article I read. Wow, no use for men folks!
The adult females come out of the ground year round but are usually the heaviest from July through October. There are only females; there are no males. The female beetles lay eggs and, like other unwanted garden beetles, the larvae that come from the eggs drop to the ground and feed on the roots of the host plant for 6 to 8 months – after which they pupate and come out of the ground as adults the following year.
I wrestled with reality for 36 years, and I'm happy to say I finally won out over it.
