BUTTERFLIES OF THE VICINITY OF NEW YORK CITY 



20. Silver-Spotted Fritillary (Argynnis aphrodite). 



Orange-brown with black spots. Closely allied to A. cybele, but 

 may be separated from that species by its smaller size and the absence 

 of the dark basal area on the fore wings above in the male, and also 

 by the narrower yellow field between the outer margin and the brown 

 basal color on the under side of the hind wings. It is found in wet 

 meadows and overgrown fields in June and July. The caterpillar 

 hibernates. It feeds on violets. 



21. Silver-Bordered Fritillary {Argynnis myrina). 



A small orange-brown butterfly, with black markings and silver 

 spots on the hind wings beneath. It is common in swampy places 

 and damp meadows. It is on the wing from the latter part of May 

 until early in September, and it is triple-brooded. It flies rather 

 slowly amongst tall grass, when not feeding. When alarmed, it flies 

 only a short distance, and then settles again in the grass. The cater- 

 pillar feeds on the violet. Those of the last brood hibernate. 



22. Meadow Fritillary (Argynnis bellona). 



Common in this neighborhood and found together with Argynnis 

 myrina, but it is not as abundant as the latter. In general appearance 

 it very much resembles A. myrina, from which it differs in the absence 

 of the silver spots on the hind wings beneath. The caterpillar feeds 

 ")n the violet. The last brood of caterpillars hibernates.
