It's definitely not a ladybug larvae, they are black and have yellow/orange spots. I'd tend to agree with fineexampl. Looks like eggs to me, too (unless they walk! ) and I agree that I'd leave them were they are. 99.9% of all insects are no nasties and won't harmy your plants and a lot of them (especially larvae) eat aphids and the likes!
i did a few searches this morning and it's positively eggs. i just couldn't pin down a specific species. all my searches came back with some kind of beetle or ladybird/bug variety.
the larvae areas chiliac described. kinda ugly and black.
They're some form of beetle eggs. If you leave them be, just keep an eye on them. They could just as easily be a harmful beetle as a helpful one. I had beetles eating my tomatilloes that laid eggs that looked much like that.
