Butterflies of North Carolina, South Carolina, Virginia, and Georgia
By Harry E. LeGrand Jr., Jeffrey S. Pippen, Derb Carter, Jr. and Pierre Howard
THE UNIVERSITY OF NORTH CAROLINA PRESS
The most comprehensive southern butterfly guide available
Few creatures are as enchanting and magnificent as the butterfly. This field guide introduces more than 200 butterfly species found in the Southeast, complete with color photographs that not only identify them but also reveal their unique beauty.

What’s included:
* Nearly 600 full-color images of butterflies in their natural habitats
* Information on structural and behavioral features, from antennae attributes to flight styles
* Maps for butterfly sightings at the county level in each state—North Carolina, South Carolina, Virginia, and Georgia

Zhang, J., Cong, Q., Shen, J., Song, L., & Grishin, N.V. (2023) Genomic analysis reveals new species and subspecies of butterflies. The Taxonomic Report 11(6): 1-62.

Abstract

Large-scale genomic sequencing of butterfly taxa reveals new findings that are presented here. While we focus on detecting species by comparative genomics and define subspecies as groups of populations genetically differentiated from each other but not as strongly as species (that is, subspecies as species in the making), we report other adjustments to butterfly classification.

Additional taxonomic refinements suggested by genomic analysis of butterflies.

Abstract:

Comparative analyses of genomic data reveal further insights into the phylogeny and taxonomic classification of butterflies presented here. As a result, 2 new subgenera and 2 new species of Hesperiidae are described:
