I had read someone say that thrips can cause nodules or bumps on forming buds.

Is this a photo of such damage?

Those look like the bud bumps, known as enations. Originally they were blamed on aphids but they happen when there are no aphids. So these days they are generally blamed on thrips. However, it has never actually been proven that it is thrips and there are other insects that could, in theory, also cause them. It's not difficult to find thrips on daylilies so hard to rule them out.

Sue - so this is definitely not normal for bud/bloom formation? I see this off and on throughout my garden daylilies.

The assumption is that it's caused by some pest that we pretty much all have. So in a way that might be considered "normal" Hilarious! Is there anyone reading this thread who doesn't see bud bumps?

I've noticed certain cultivars get them more than others.

I am in a continual battle with thrips. If I don't spray, buds will have "bumps" - very similar to what is seen in Becky's photo. Numerous "bumps" will also have a tiny peak, or pointy area. Color-damage is very evident on dark blooms after they open if the buds show these "bumps". I'm sure pastels and near-whites have color damage, too, it's just not as noticeable. If you look very closely at an open bloom or nudge it, you can generally see thrips move, even though they are teeny tiny. They can fly!

If I spray, buds appear to be normal and smooth-surfaced with no evidence of color damage to the bloom when it opens.

I get them on my daylilies from aphids. Maybe a thrip can cause the bloom to look like that and an aphid can too? I wash my daylilies. I started late this year, even though I started on time. I was about a month late because spring started early. I already had scapes and buds. I thought what a washout this year will be with my buds having bumps. Alot of my moonlit masquerade blooms looked bad, but they all bloomed perfect. Try to determine the pest. Aphids leave dandruff and thrips show up as... I had to leave blank because I have not had thrips. Treat the daylilies and I hope all your daylilies bloom beyond expectations because we all know there is joy in a flower.

I doubt it is aphids because I get the bud bumps here where there are no aphids on the daylilies. There are thrips though, but that doesn't necessarily mean they do it, although they may be the guilty party. Stopping the bumps by treating for thrips also doesn't convict them because whatever was used for the thrips potentially may also control another pest. What would be enlightening would be if someone got the bud bumps without having thrips (and we may well all have thrips), or had thrips without treating for them and did not get the bumps.
