The Sphinx Poecila

When the boys and I shot a few pictures of a strange looking caterpillar on the bog walk, we didn’t realize it would be quite a to-do.

Since the caterpillar was so unique, we sent a few pics to the head honcho of the bog walk just in case other patrons may have been interested.

This is the response that we got from him: 

Hello,

I e-mailed Professor David Wagner at the University of Connecticut who wrote the book "Catepillars of Eastern North America", Princeton University Press, 2005.  Here is what he said:

I would guess it is a prepupal Sphinx gordius.  Some sphinx caterpillar turn rather red (they are green while feeding but go on a walkabout looking for a good pupation site and become increasingly reddened).

In his book he says: "Green to blue-green or rarely purple-brown."  The common name is Apple Sphinx.  It occurs central and eastern Canada south to central Florida.  If you google the scientific name "Sphinx gordius" you get some great pictures.

Thanks - the photograph is just wonderful.

Before Jim Bird got back to us, we posted a pic on Facebook to see if anyone could identify the mystery bug.  The posts from our good friend Anne Cowperthwaite Malena are just too entertaining not to share:

Thanks to Anne Malena, we not only were entertained with the banter over a 24 hour period, Soren is now somewhat famous amongst the caterpillar lovers of America! 

Our find can be found on this website:  http://www.silkmoths.bizland.com/mePenobscotsphlar.htm

Soren was so excited to see that he is now “famous” due to his caterpillar find!
