Larva. — "Mr. Crewe thus describes the caterpillar: 'The ground-color 

 is pale 3-elIowish-green, with two whitish-yellow, central, dorsal stripes ; there 

 are two subdorsal stripes also whitish-yellow; ihc spiracular si ripe is Itright- 

 yellow^and orange ; the back and sides are occasionally studded witii a few 

 black tubercles, and always with a few short, wdiitish hairs; the belly is desti- 

 tute ot" markings. It feeds on the common buck-1 liorn {RJuimnus catharticus), 

 and is full-fed about the middle of June, when it i'orins an earthen cocoon, 

 and therein changes to a dark reddish-brown (hrysalis.'" — Newman's British 

 Moths, 176. 



lierrich-Schaeffer states that in Europe the larva feeds on the sloe or 

 wild plum, " stone-fruit," and white-thorn.
