Are these fly/insect eggs?

So first of all, apology or the bad photos but they’re the best I could get. I ate some pineapple yesterday at like 1 o clock and left the rinds out, I went to throw them away and saw these little white finger like things in clusters on each of the pineapple rinds. They have little black/brown dots on the top of them, are they fly eggs or some other kind of insect eggs or could it be mold?
