My zucchini have just started to be harvestable but I'm still waiting for the day when I have more zucchini than I can eat. Won't that be wonderful.
While hovering over the still-unproductive zucchini, I noticed what seemed to be 3 pests:
1) green shield bug (maybe a stink bug, I thought)
2) orange eggs on underside of leaves
3) clustered spiders (I thought)
Turns out these are all the squash bug, in various stages of development, and should ALL BE KILLED. Which should be pretty easy if you can catch them early. The eggs are bright orange, the spiders are actually squash bug nymphs and are white with black heads and legs, and the adults start out green, like a stink bug, but later turn brown/black.
I also ate my first barely-ripe grape tomatoes today. Many more to come.
