Dead caterpillar? - Eurytides marcellus

Dead caterpillar? - Eurytides marcellus
Columbia, Boone County, Missouri, USA
May 18, 2010
I know this is E. marcellus's final, prepupal instar, and it has even attached it's silk girdle (though you can't really see it in this picture). But little brown splotches have appeared in a couple places on the caterpillar and I'm wondering whether these might be indicative of a fungal infection of some sort. The caterpillar was raised in a relatively large aquarium with an abundant supply of pawpaw and I cleaned out the frass regularly, but I can't think of any other explanation for the brown splotches.

Thanks for your help.

It formed a chrysalis! But th
It formed a chrysalis! But the chrysalis is brownish? Perhaps this camouflage? It would be consistent with this.

 
The color varies,
brown, grayish, green, pinkish, sometimes mixed on one chrysalis. It seems that they can match the background to which they are attached (true??), at least somewhat. Or, maybe the caterpillar "knows" what color it's going to be and looks for a similar background? Sometimes they goof, but usually they do a pretty good job of blending in.
