Funeral Duskywing Overview

The Funeral Duskywing is a butterfly that is found in most states of the United States as well as parts of Mexico and Central America. These butterflies can be found in deserts, and lowlands that are warm, as well alongside roads. At first glance, these butterflies look like moths but are in fact not as they don’t have the key characteristics of a moth. 

In general, moths like to leave their wings open when resting whereas butterflies will keep their wings closed unless basking in the sun. Another key thing to look out for when trying to tell these two insects apart is to look at their antennae. A moth’s antennae will be feathery while butterfly antennae tend to be more wiry and slender. Lastly, moths and butterflies have wings that function in different ways. A butterfly is able to move its wings independently of one another whereas a moth’s wings are flapped together. There are a few other differences between the two insects, these are just the easiest to spot.
