Black-bordered Crescent

Sorry, there was a misspelling in my suggestion: Tegosa anieta nieta is wrong, should certainly be Tegosa anieta anieta.

There is no difference, skippers are butterflies ;-)... Just kidding... Hesperiidae or Skippers are the only family of the superfamily Hersperioidea, so there is from the systematics a separation from the other butterfly families Nymphalidae, Papilionidae, Pieridae Lycaenidae and Riodinidae (superfamily Papilionidea. In general and not going too much into details: Skippers are usually small (however, there are also larger ones!), not have really "clubbed" antennae like usual butterflies, but some kind "hooked" antennae. The eyes are quite large and the body compared to the allover size is also quite large and "plump". Caterpillar usually have really large heads (in German they are called/translated "Large-headed butterflies"). Here are some links of my butterfly blog for more info: http://blog.projectnoah.org/post/48198637296/lepidoptera-part-3 http://blog.projectnoah.org/post/48440401780/lepidoptera-part-4 http://en.wikipedia.org/wiki/Skipper_(butterfly)

Tegosa anieta anieta, not a skipper, but Nymphalidae, Nymphalinae, Melitaeini.

It's a butterfly of some kind. Moths don't have clubbed antennae. :)
