Beginner Gardening: Butternut squash problems, 0 by violets22

I have some butternut squash plants which were doing fine until recently. Their old leaves have been turning yellow, then brown and shriveled, and finally die. Now, many of the leaves (including the newer ones) have gray powdery blotches (maybe mold?) on them and there are tiny moths by the plants. When I rustle the leaves, a whole bunch of these moths get disturbed, fly into the air, and land around another squash leaf. I live in northeast Florida. Pictures of all the problems, including a small photo of one of the moths on a screen, are included.

Does anyone know why the older leaves are dying, if the gray blotches and moths are harming the plants, or of a solution to these problems?
