Dateline: August 29, 2014
I met a new butterfly this week. This particular butterfly is one of the skippers. Skippers are in the Superfamily Hesperioidea, as opposed to say, Swallowtails or Milkweed Butterflies that are in the Papilionoidea Superfamily encompassing Butterflies (excluding skippers).
Skippers are a diverse bunch and often hard to identify. This skipper was rather large, dull in color, but it intrigued me just the same.
Skippers can be somewhat trying to photograph. You see they…umm…skip from flower to flower and it is often nearly impossible to keep up with them. Luckily, this guy was drawn in by the nectar of Carolina Redroot (Lachnanthes caroliana) and seemed momentarily engrossed enough in his drinking habit that I was able to snap a couple of photos.
Unfortunately, I didn’t get great angles and it is imperative to have both the ventral and dorsal views of skippers to determine species. One dot, dash or directional mark can be a determining factor in getting it down to the correct species.
There are several subfamilies of skippers and because of the size, I knew it wasn’t one of the Grass Skippers (Subfamily Hesperiinae) as they are substantially smaller.
It had similar attributes to the Longtail Skippers that are Dicot Skippers (Subfamily Eudaminae). Dicot Skippers eat
There are also Spread-wing Skippers (Subfamily Pyrginae).
A quick check and I was able to determine it is one of the Cloudywings (Thorybes spp.). Comparing photos, I gave a preliminary identification as possible Confused Cloudwing (T. confusis).
As I always do with skippers, I checked in with my twitter pal @AndyBugGuy. Unfortunately, he reports there isn’t enough detail in the photos to provide a firm identification, but he did narrow it down to two possibilities: (1) the one I guessed or (2) Northern Cloudywing (T. pylades). Now it is up to me to keep my eyes peeled to see if I can get better shots or at least a good look myself to firm up the identification by paying close attention to the subtle differences in markings.
Often the larval host will help in determining butterfly species. In this case, I’d be more confident with it being a Northern Cloudywing (T. pylades) since there are numerous Desmodium species that are listed in the HOSTS database and occur on my property.
On the other hand, the HOSTS database lists Lespedeza spp. (bush clover) as the only larval host for T. confusis and I don’t have any of that currently at my place, although I’m sure it is close-by in the neighborhood.
THEN I found the following notation at the Butterflies and Moths.org Website regarding food choices for the Confused Cloudywing:
Heck, I’ve got T. florida growing in the back area, very close to the stand of Redroot that this guy was feasting on. How’s that for documented confusion.
So, while the Cloudywing may or may not be a Confused, this blogger is “Confused” indeed. I hope some additional flutterers will return for me to study further. However, if it gets down to having to dissect the genitalia, I’m out! Identification to genus will be good enough for me.
