A List of the Butterflies of Philadelphia, Pa

Abstract

Appreciating the value to students in geographical distribution of faunal lists of a given region, with notes thereon, on the interest that such lists have for beginners in the same field in after years, we have concluded to publish here a list of the Diurnal Lepidoptera known to us to have been taken in the vicinity of Philadelphia. A circle drawn around the new City Hall, with a radius of ten miles, is the line of limit to the “vicinity” here treated of.

Range collapse in the Diana fritillary,Speyeria diana(Nymphalidae)

“…The Diana fritillary, Speyeria diana (Cramer), is an eastern North American fritillary that has become increasingly rare across portions of its distribution (Rudolph et al ., ; Campbell et al ., ; Ross, ). Early accounts describe S. diana as once ranging from coastal Virginia westward to Missouri and Arkansas, southward to the northern tips of Georgia and Alabama, and northward throughout the Ohio River Valley from western Pennsylvania to Illinois (Edwards, ; Strecker, ; French, ; Hine, ,b; Scudder, ; Skinner, ; Clark, ; Clark & Williams, ; Clark & Clark, ). This species has since disappeared from much of its range, including coastal Jamestown, Virginia, where the type specimen was described by the Dutch explorer, Pieter Cramer (Cramer & Stoll, ).…”
