Found these eggs on higher-up spines of my Trichocereus cactus. Any idea who they belong to?

Small white spherical eggs, with small orange/brown dots, are laid in straight lines on a cactus spine

It looks like cutworm eggs. If they get really dark soon, they're almost definitely cutworm eggs.

It's interesting they're on a cactus spine.
Nice, I was hoping for butterflies. Moths are just as cool! (Assuming that is indeed the case.) There were some other eggs which looked like they had already hatched, and those looked darker.
I thought it was interesting. I wonder if they lay eggs like this on native Opuntia spines too, or if the height of Trichocereus makes them more suitable.
That's still a possibility! Have you spotted the larva? I'm guessing they're on a nearby plant, probably near the base.
The eggs look a bit old - nearby spider webs swept over them and such - so I don't think they hatched too recently... but that's a good idea, I'll see if I can spot anyone left hanging around. Will be checking them every day now anyway, so I'll see the next batch for sure
Nice! They come out at night.
