Quite possibly red spider mite. I spray with soft soap (Savona),
which is effective against pretty well every insect/mite except
scale, but melons may be one of the plants that doesn't like it.

The alternative is washing-up liquid solution with a dash of
methylated spirits, but the same plants that don't like soft soap
won't like that, either.
