They look like ladybug eggs - yellow, oval shaped, and attached to the leaf with a small pedicle.

Yup, I'd say ladybug as well. Cool! :-) Wish I'd get more in my gardens. Keep us updated on their progress... with pics! :-)

Doubt they're ladybug eggs. Her eggs are spindle shaped and stand on end.

These look basically round. Likely caterpillar of some kind.

I have a gardening book with a picture of ladybug eggs. They're yellow. Most are oval but a few are perfectly round. Ladybug larva are gray, with ridges of black spots down the length of the body which is more elongated than oval. There are also a few yellow spots on the larva.

I may have the same issue - here's a very similar picture from my garden today.

The eggs appear bright yellow and perfectly round.

If they're ladybugs, I don't want to remove them, but I have seen very few ladybugs around - in fact, none in this particular bed. The only pests I've seen in the garden are green aphids (again, not near the tomatoes) and lightning bugs. Will lightning damage the tomatoes, and could this be their eggs?

Thanks!

That photo is misleading as it pictures the eggs head on.

Lady beetle eggs are spindle-shaped (that is, football-shaped)and stand on end as in this photo

Lighning bug larva eat bugs, too--so if you get them, you are very lucky!

Mary, lightning bugs lay their eggs at or just under the soil surface, where the larvae will hatch and live. Lightning bugs are not at all harmful to anything, and the larvae are considered beneficial predators.

Def lady bugs.
Jean, your beetle with the spindle eggs is not a lady bug!
Socalgirl beetle is a lady bug.
