I have also seen a few of the bugs shown in the second picture. They are the kind that hide from you--they move around the stem of the plant to hide from you as you move. Are these the bugs that laid the eggs?
I wonder if they are eating my butterfly eggs? I usually have a lot more cloudless sulphur caterpillars by now. This year I only have a few. I'm also having an ant problem so that could be contributing to the problem.
FYI I live in San Diego

Are these teensy little tannish white eggs? If so, I have found them many times on things.

I find them on my fig netting, laid along the strings and I've found them on laundry when I used to hang the wash out to dry. Several times, I've seen teensy little black caterpillar-looking things that resemble banana seeds (on the inside of the banana.)

I've been trying to find out what these eggs are for about three decades! I never knew if I should destroy them, or leave them be.

Thanks,
