The Wild Indigo Duskywing is one of the most common duskywings in central New Jersey, but hasn't been very common in my garden.  I usually see one or two of them every year.  Their numbers were significantly higher in 2004.  It is difficult tell one species of duskywing from another.  Although some of the duskywings pictured here look much different from one another, they don't look anything like any other species of duskywing I have seen pictures of.  It is possible that all of these aren't Wild Indigo Duskywings.
