Very Hungry Caterpillars

I used to think caterpillars were cute. My opinion has drastically changed since we moved here to North Carolina! We have now had three types of caterpillars infest our tiny yard in the last 3 months. First, the skinny little broccoli caterpillars destroyed our broccoli crop.

Then, the nasty black caterpillars attempted to consume the tree in our front yard. We waged war against them by stepping on any that tried to cross our driveway and cutting down infested branches. We were so attentive to their efforts to take over that Calvin now points up into the tree and says "uh-oh!" whenever we are outside. There are now yellow caterpillar insides all over our driveway, but we won.

Now we have these guys all over our pepper plants: Tobacco Hornworm

And these on our tomatoes:

Apparently these white things are parasitic wasp larva. Disgusting! I'm all for something killing the caterpillars, but I'd prefer not to have wasps instead.
