Cute bug?

I saw this Pandorus sphinx caterpillar (Eumorpha pandorus) on a grape vine last weekend. 
These caterpillars belong to the Sphingid family (Lepidoptera: Sphingidae), which includes the infamous tomato and tobacco hornworms. Although the caterpillars are often referred to as hornworms because of the "horn" at the tip of their abdomen, the adult moths carry the more attractive names of Sphinx or Hawk Moth. This caterpillar doesn't have a horn though. Instead it has a thin curved hook and an eye-spot on the tip of its abdomen. As they get older they lose the hook altogether, leaving only the eye spot.
This caterpillar was an amazing dark red color, but I saw others that were a much lighter rusty-orange.
When they feel threatened Sphingid caterpillars often rear up and tuck their heads back, in a motion that is reminiscent of a serpent preparing to strike.
But let's face it. It just makes them look ridiculous and...kind of cute. In fact, I think they ought to be put in the running for cutest bug. Or at least be in the top 10.

  1. I found another caterpillar of the same species in August of 2014. That post can be found here: http://www.crunchysegments.com/2014/08/not-so-cute-bug.html
