Orange dog 

 Papilio thoas Linn. 

 A large, brownish caterpillar with conspicuous angular, cream-colored markings on 

 its miiidle and at its posterior extremity, is sometimes rather abundant on prickly ash.

 north as Albany, though it is quite common near Poughkeepsie and 

 undoubtedly more abundant farther south. Dr Smith states that only 



single examples occur throughout New Jersey.

full grown caterpillar is 

 about 2^ inches long, 

 dark brown in color

 thoracic segments are 

 slightly swollen and 

 marked with several yellowish ocellate spots, so that when the head is 

 drawn under the anterior thoracic segments there is a strong resemblance 

 to a mask face. This caterpillar when irritated, as in the case of its allies, 

 is capable of projecting two long, fleshy, orange-colored tentacles from a 

 fold just behind the head. These emit a very disagreeable odor and are
