Giant Silkworm

I was working in the backyard on Sunday when I came across this giant caterpillar on a stick.

This has to be the largest caterpillar I’ve ever come across. Thanks to What’s That Bug I was able to discover that this is a Giant Silkworm. The Cecropia Moth (which is what the Giant Silkworm will become) is a very large moth. According to the Cecropia Moth – Life Cycle website, the Cecropia Moth has a wingspan of 5 to 6 inches!

There is also a picture with a quarter to try and show how large the Giant Silkworm is. Note that the silkworm appeared to be trying to protect it’s head in this picture as it sort of pulled it in under neath it’s body.
