Caterpillar Head Parts
Caterpillars have odd parts on their heads. We're used to two eyes, two ears, one nose, two eyebrows ... you get the picture. They are quite mixed up! Or we are.

Photographing a Tiger Swallowtail caterpillar was fun. After downloading it, I was shocked to notice that its head is blue. OK, so I am NOT the most observant of things. It takes a sledge hammer every now and then to open my eyes. I marked some of the photos with head parts, including the spinnerets, where its silk comes from.

Of note are their 12 eyes. Yes 12. With these 12 eyes they see light and dark and possibly some colors.

The 'eyes' in the first photo are not eyes but simply markings on its skin.
