Eastern Pine Elfin

Spring Azure
Question Mark
Gray Comma
Green Comma
Compton Tortoiseshell

Mourning Cloak
Red-spotted Purple
White Admiral
Hackberry Emperor

Silver-spotted Skipper
Dreamy Duskywing
Sleepy Duskywing
Juvenal's Duskywing

Those are just some of the northern ones that I am familiar with. So when you are planning that complete butterfly garden, don't forget to consider some of the native tree and shrub host plants. Or, if you are just looking for some native trees and shrubs for your yard, consider selecting some of those that will also benefit your local butterflies.
Thanks for mentioning the shrubs & trees. You're right; I think "butterfly=flower." The book I'm reading now mentions speckled alder (Alnus rugosa) as being good for several butterflies. Also, the book mentioned a carnivorous butterfly (who knew?) likes a certain aphid that likes speckled alder.

This year is the one we ditch neatness in favor of wildlife.
