Don't plant squash next to muskmelons, unless you want squash bugs eating your melons, too. I've had it happen twice, including this year with a squash that I previously though squash bugs didn't like much. (But, apparently, they'll eat it if they don't have anything else nearby.)
Anyway, the squash bugs are on some of the muskmelon fruits in large numbers, it seems.
