Yellow Butterflies of the Tribe Coliadinae - Identification Guide #3681817 (License: Personal Use)

This vintage scientific illustration presents eight specimens from the tribe Coliadinae, arranged in four pairs: Black-bordered Yellow (male), Clouded Sulphur (male), Orange Sulphur (female), and Dog’s-head (male), with left-side images showing upper wing surfaces and right-side images showing under surfaces. Each butterfly is meticulously rendered to highlight diagnostic coloration, pattern, and sexual dimorphism, typical of early 20th-century field guides and taxonomic references.

Used in educational, entomological, or natural history contexts-such as museum exhibits, biodiversity websites, or digital archives-to aid species identification and illustrate morphological variation within the Coliadinae subfamily.
