I don't have personal experience with it as I have been very careful with the plants I have bought, but take a look at this: https://daylilies.org/daylily-dictionary/hemerocallis-gall-midge/
They have photos of both the adult and larval stage. If you did have it, it would have shown up with damaged buds instead of this magnificent flower.

it looks too big to be a gall midge and the wrong shape.
I have noticed the adults before and they are less than 2mm and have the characteristic 'humpy back' of a midge.

Thank you for your thoughts about Gall Midge. I only noticed the insect on looking at my pictures,
I have only bought late flowering Daylilies, the last 2 being Navajho Princess which flowered magnificently and Real Wind which is really late here and still to flower, buds good.
I removed any Daylilies a couple of years ago that showed any signs of distorted buds. Also i religiously take off the spent flowers each day. I do not compost dead Daylily material, so hopefully im on top of the deaded GM.

It's hard to tell from that angle and that magnification, but it looks more like a parasitoid wasp than a midge, to me. If so, then it's one of the good guys, in spite of the hair raising name. They eat a wide variety of sucking bugs and caterpillars.

In any case that flower is far too good to have been affected by gall midges. The colour of the flowers is often 'speckled' when there are midges and they do not open properly.
We stopped growing Hemerocallis because of them. Sad as they are a lovely plant.

Thank you all for your reassurances. There are a lot of these little insects hovering around my Sarracenias, which hopefully will entice them in for breakfast.
