Caterpillars & The Art of Survival


At first glance, the life of a caterpillar seems simple: eat, grow, avoid predation, and transform.  But in order to live this simple life, caterpillars have evolved a huge variety of adaptations and employed countless strategies.  One example is camouflage.  Few insects exhibit such an extraordinary ability to blend in as caterpillars.  The caterpillar below was found on a White Ash tree near the NBNC community garden.  Can you spot it?

 

Despite being several inches long and feeding out in the open, even during mid-day, this caterpillar seems un-phased by the many birds that fly within feet of it, looking for a meal.  It is called a Laurel Sphinx Moth.  As it feeds, it positions its body so that the black-and-yellow lines on its abdomen are parallel to the veins of the leaf on which it feeds.  A picture of the adult moth is shown below.
