Larry I've seen those bugs on my daylily leaves before but not often & I could never see any damage. I think the were eating the mushy, rotting leaves.
I had a ton of bud drop last year with all the rain we got. I'm thinking that may be the culprit. Lots of rain with little sun to dry the water being held in the leaves caused scapes to abort & buds to drop. I would have thought it wouldn't be an issue someplace warmer but if the weather stayed unusually cold that could be it.
Unfortunately this year is looking to be a repeat. It's pouring right now & will continue until Tuesday. The daylilies are all green & lush but I'm guessing bloom season will be a disappointment this year.
