Moved from Unidentified Pupae and Cocoons.
I think you're right about the family, and I'm guessing the species is Tebenna carduiella, which seems to be the only thistle-feeder in the family. My only hesitation is that this species is a stem-borer, and I don't know if it emerges to spin a cocoon on a leaf as other metalmark moths do (the description here only talks about what the leaf-skeletonizing species do).

T. carduiella cocoon

I have never reared this species, but when a moth is named after a plant, that usually means that the original series was reared, in which case the original description should be consulted, in that it might contain whatever life-history details are being sought. When this is done for the description of the species in question, we see that Kearfott (1902, Journal of the New York Entomological Society 10: 119, viewable online here) states that the cocoon of T. carduiella is "spun under the leaves and below the thistle head in any convenient partially protected angle."

Moved from ID Request. Wish I knew! Can you add a size estimate, and if possible the type of plant it was on?

thistle

They were on the leaves of thistle plants, but precisely which species I'm not sure... trying to remember accurately, but they were maybe 1cm long?
