Pat:

It sounds like a geometrid caterpillar as you already know.  Bev pointed
out a couple of very good web resources.

A very good book for caterpillar identification is part of the Princeton
Field Guide Series.

Wagner, D.L. 2005. Caterpillars of Eastern North America. Princeton
University Press.


Lepidoptera are not my interest or forte.  However I have been able to
use this guide effectively.

Subject: [NatureNS] Twig Caterpillar, Halifax

Earlier this week I found a caterpillar which looked just like a 
twig.  If it had not moved, I would have thought that it was a twig 
fallen from the overhanging Norway Maple.  Its skin was the same 
greyish brown colour, with creases around its circumference like the 
growth rings in the bark of a maple twig.  However this "twig", which 
was more than three inches long, was inching its way across a 
colleague's windshield.

I've looked at a few online sites, but don't have an ID yet.  Bev 
Wigney has a "twig caterpillar" on her site 
http://www.pbase.com/crocodile/image/45413515 which looks somewhat 
like it, but not exactly.  Can anyone suggest other sites, or an ID?

	Cheers,

	Patricia
