GENUS GRAPTA KIRBY (THE ANGLE-WINGS) 



Medium-sized or small butterflies; fore wing strongly 

 acuminate at end of upper radial, deeply excavated on outer 

 and inner border; hind wing tailed at end of third median 

 nervule; cells on both wings closed; palpi heavily scaled be- 

 neath. Upper side of wings tawny, spotted with darker, 

 under side mimicking the color of bark and dead leaves, often 

 with a silvery spot about middle of hind wing. The butter- 

 flies hibernate in winter. Eggs taller than broad, tapering 

 toward top, which is flat, adorned with a few longitudinal 

 ribs, increasing in height upward, laid in clusters, or strung 

 together, then looking like beads. Larva with squarish head; 

 body cylindrical, adorned with branching spines. Chrysalids 

 with head bifid; prominent tubercle on back of thorax; two 

 rows of dorsal tubercles on abdomen; compressed laterally 

 in thoracic region; color wood-brown or greenish. The 

 caterpillars feed upon plants of the nettle tribe, including the 

 elm and hops, though willows, azalea, and wild currants are 

 affected by different species. 



The genus is confined to the northern temperate zone. We 

 have about a dozen species in America, of which five have been 

 selected for illustration.
