My bean plant looks good except this one leaf this bug was attached to. As you can see that leaf is very wilted. I have never seen this bug before. Do you have any idea?

I don't know a thing about bean plants or insects that attack them but I think I see wings on that bug in your photo and I wonder if it could be a Bean Seed Fly?

Hopefully one of our knowledgeable vegetable growers will be along and be able to identify that bug and offer tips/advice on eradication.

You could be right, Lin. Those flies are susceptible to fungal diseases and infected ones often die and get stuck to things. There's a pic of that also on Bugguide, pretty much looks the same:

Edited - forgot to add the fly in this pic is not a bean seed fly.

I do see a white spot like substance beneath that fly in Toni's photo, so the bean plant could be infected with a fungal disease that attracted the fly and the fly isn't the problem but rather a fungal infection? Very interesting!

The white stuff is most likely the fungus that killed the fly. Often you'll also see flies stuck to objects by the head and those too were killed by entomopathogic fungus. This is a reason why using fungicides can cause an increase in insect pest problems by also reducing the fungi that kill the pests.

I don't spray ANYTHING. EVER. I don't even use "organic" sprays or granules or anything. My garden inhabitants have to be tough to survive Rolling on the floor laughing
I have never seen this before.
I am worried that it is the beans that are infected vs the bug causing a problem.
Well, hopefully picking off the wilted leaf will be the cure.
Thank you ladies
