This ubiquitous skipper can be found in a diverse variety of habitats. They are very common everywhere in eastern North America, but are more likely to be seen in the mountainous regions on the west side of the continent.
The Silver-Spotted Skipper is mostly a mottled brown color, but when its wings are closed (up), a large white-silver patch can easily be seen on the lower hindwings. If their wings are open (flat), a yellow band running parallel to the body can be seen on both forewings. As a Skipper, this butterfly's antennae are slightly bent or curved at the tips, not completely stiff and straight.
