with black and yellow lines. On the body are numerous branched 

 black tipped spines. The wings of the adult butterfly are reddish 

 brown bordered with a darker brown. A silvery comma mark on 

 surface of hind wings. 



The larvae of the Mourning Cloak Butterfly feed upon the leaves of 

 willow, poplar, elm and dogwood and are interesting objects. There 

 are two generations a year, the adults wintering over and appearing 

 in early spring. The adults of the second brood appear in July. 



DANAIDiE 



The monarch butterfly (Danais archippus Fab.) is a common insect 

 but not of economic importance. Its larva feeds on milkweed. 



SPHlNGIDiE (HAWK MOTHS) 



The Hawk Moths are readily recognized both in the adult and the 

 larval forms. The adults are strong fliers and are beautifully colored. 

 They usually fly about dusk. The larvae are large and often ornamented 

 with stripes, and usually have a horn near the hind end of the body. 

 They feed on a great variety of foliage. Ordinarily they are kept under 

 control by parasites and birds. When occasioning damage they are 

 readily controlled by spraying with arsenicals and by hand-picking.

The Tobacco Sphinx {P. sexta) is very similar to the preceding, 

 feeding on the same plants. It is more abundant in the South. The
