Mutated Caterpillars

Once a year, caterpillars dangle on silken threads from the trees here. I often don't notice them until I suddenly realize that my hair is full of squirming worms (and if you've ever seen my hair when it gets long, you'll know that I might not notice the caterpillars right away). I wonder if they've mutated this year? In the past they've always been green...

By the way, today is yet another glorious day in paradise.
