Do flames emit UV?

IIR, hydrogen flames can emit enough of their energy in the UV for that to be a serious issue - both direct human exposure, and degradation of exposed surfaces and equipment.

lived with candles and kerocene lanterns, etc for years and the odd bug will go nuts and spiral in, but not very many
but all in all, there are way less bugs everywhere now

No but they emit smoke
We use UV/IR combo Flame detectors at work for this purpose.
