How do you tell a Striped Hairstreak butterfly from a Regal Fritillary butterfly? By using Butterflies of Pennsylvania, the most comprehensive, user-friendly field guide to date of all of the species ever recorded within Pennsylvania's 46,056 square miles.
Over 900 brilliant colour photographs illustrate both the upper and underside of male and female specimens of each species, including skippers. Information on distinguishing marks, traits, wingspan, habitat, larval host plants, and handy facts offer assistance for field identification. The images depict the species in their native environments, as well as finely detailed museum-quality mounted specimens. County-by-county maps show where each species has been recorded within the state, and graphs detail when they are present and most likely to be seen.
Butterflies are arguably the most recognised, studied, and beloved of all insects. They are essential to healthy ecosystems, agricultural viability, and ultimately human and animal survival. Butterflies of Pennsylvania will serve as a handy reference for a broad readership including students and educators, backyard butterfly enthusiasts and gardeners, conservationists and naturalists, public and school libraries, entomologists, lepidopterists, and butterfly watchers in general.

"This work has all of the features that make field guides to a region's butterfly fauna useful to anyone with a serious interest in that fauna [...] the book is a bargain and a must for anyone with an interest not just in Pennsylvania's fauna, but the northeast fauna as a whole."

"This guide is tailor-made to suss out the vagaries of cloudywings or little brown job skippers from photos, notes or sketches made in the field. That's where the 900+ color photographs of pinned (not field) specimens outshines every other field guide available for the mid-Atlantic, and where subtle differences in eye color or wing pattern or flight time can be studied and weighed in comparison. I can't think of a better resource for the photographer-naturalist with an interest in butterflies. It fully deserves its recognition as a winner in the 2017 National Outdoor Book Awards in the field book category."
