This isn't the best photo but I don't have a way to take a better one(bugs are in middle). It looks like some stage of a fungus gnat but internet pictures show a black face, this one doesn't have that. I do struggle with fungus gnats but not horribly. Hydrogen peroxide and neem have kept me ahead of them mostly. But I will find these long, cream colored larva bugs crawling on my plumeria leaves. Do fungus gnat larva crawl on the plant or do they stay in the substrate only?

Also, this plumeria is still actively putting out leaves but the older ones seem to be suffering from something. What do these leaves tell me?

Fungus gnats go through several stages between egg and adult but, all those stages (until adult) take place in and on the soil, not the leaves.

Have you tried simply washing them off with warm soap water?
