I have about half a dozen tomato plants planted on one side of the run, and noticed that some of the leaves were looking all lacy, being eaten by something. So I investigated and found lots of little blue caterpillars with red heads. Don't know what they were, but I had 18 beady little eyes watching my every move, and 9 hungry beaks scrambling to get each tasty morsel as it came through the wire! Looks like the girls save my 'maters! I'll have to share with 'em when they get ripe.
