It looks like flea beetle damage. Not much you can do, but hopefully the flea beetles have moved on to another growth stage, enabling the plant to grow some new leaves.

Yes that looks like major flea beetle damage, hopefully just on the older leaves (assuming squash plants). If you have an eggplant in your garden and it's ok then this damage might not be FBs. They would go for your eggplant first....in my experience anyways. It's an excellent trap plant for FBs -they appear tiny black specks of pepper on leaves and jump as you approach. Can be best caught in the action on leaves at dusk when they're reluctant to leave the plant.

Yes it is a squash. I have had flea beetles on my cabbage and broccoli this year. My eggplants had some damage to but I never have seen this on my squashes. They all get treated with a rotation of azaguard and pyganic. Thanks for the help.
