Caterpillars of all shapes and sizes freak me the F*** out so I do my best to avoid them. The funny thing is they have a way of finding me, I guess they can sense fear.
I am not much of a gardener, but I did have one sad looking parsley plant on my patio. That was until I noticed that a parsley caterpillar had moved in... it took him three days to eat every leaf off my plant. Then he moved on or got eaten by something else. Here is a quick video of him nom, nom, nom-ing away on my plant.
FYI... this little guy turns into this when he grows up
