I was reminded by Madam Moderator that this is Science and Nature.
We had very small insects, which I am told are aphids, populating our vegeetable garden, esp the tomato plant. I hosed down the leaves, to no avail. All of a sudden, the aphids population decreased. Then we noticed about 3-4 lady bugs on the leaves. Looks like theey stopped by to consume the hapless aphids.
Soon the aphids disappeared. And so did the lady bugs. Isn’t nature wonderful?
