The Brown Elfin is widespread throughout the northern half of Wisconsin, but is seldom very abundant. Mogens C. Nielson in his book on Michigan butterflies says that this species flies low to the ground and may therefore be easily overlooked, but this is also true about the Henry’s, Frosted, and Hoary Elfins. The Elfins, like the Hairstreaks, have a very short flight period in an area, and coupled with the spring flight time, it is difficult to get out into the field when they are actually flying. Consequently, even in an area when you know they occur, you may not be able to observe adults flying every year.
