BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 
This butterfly may be recognized at once by the white net-like 
marking and large eye-like spots on the under surface of the hind 
wings. Common in open fields and along roadsides. It is double- 
brooded and flies from May to October. The caterpillar feeds on 
cudweed (Guaphalium) and on wormwood (Artemisia); it draws the 
leaves or flowers together and forms a rude case, within which it lives. 
The species is found throughout the United States and Canada. 
37. Red Admiral (Pyrameis atalanta). 
Occurs over all North America and in Europe. In this vicinity 
it is sometimes very common, from the latter part of May until No- 
vember, and it is double-brooded. The butterfly is brown with a 
broad red band across each wing. It is found usually along wood 
paths or in open woods and fields. The caterpillar draws together 
the edges of a leaf and forms a commodious cavity which shelters it. 
It feeds on nettle, hop and false nettle (Behmeria). 
38. Buckeye Butterfly (Junonia cenia).
