The zucchini leaves are also bright!
This is a great time to scout out the undersides of the leaves for any unwanted squash bug eggs because all unwanted critters stand out like this guy on the upper right:
I get closer to him and he starts to look familiar.....
Peek-a-boo, Mr. Fly. I see you!
All that being said, this is how I check the undersides of my leaves, especially the squash and zucchini plants daily, but for some reason I seemed to have missed a cluster of squash bug eggs on this very same plant this morning because when I came home today I saw a battalion of little squash bugs on this same plant photographed above. I think I got them all, but I can't be sure. I've got my fingers crossed!
