Species Feature #7, Red Admiral

The photos for this entry were taken on a camping trip to the Outer Banks this past July. Nonetheless, the Red Admiral is very much relevant in the DC area. This species is relatively easy to identify from a top view. The white spots (on a black background) on the forewing tip are fairly distinctive, and you can't miss if you also see the black-fading-to-brown central coloring with orange bands around it. I don't have a good shot of the ventral view, so I'll let Wikipedia handle that for you. Note the mottled coloration and pink bar. I have to say, when I first started browsing a butterfly guide the biggest shock to me was how many species exhibit drastically different patterning on the "top" (dorsal) and "bottom" (ventral) of the wing.


Isn't she a beauty? Also, why do I inherently think of all butterflies as "she"? Am I unconsciously sexist, or is that just over-analyzing?

Vanessa atalanta Quick Facts

Common Name(s): red admiral, alderman

Taxonomic Breakdown:

  • Kingdom - Animalia
  • Phylum - Arthropoda
  • Class - Insecta
  • Order - Lepidoptera
  • Superfamily - Papilionoidea
  • Family - Nymphalidae
  • Subfamily - Nymphalinae
  • Tribe - Nymphalini
  • Genus - Vanessa
  • Species - atalanta

A superfamily, a subfamily, AND a tribe? Really? I think this is brought on by 1) a staggering number of known species in order Lepidoptera and 2) biologists' obsession with the beauty of butterflies. I'm poking fun, but honestly in this case such minutiae are certainly warranted.

Conservation Status: Not Assessed

Range: This butterfly is found all over the place. In North America, it spans Guatemala to Canada, Hawaii, and the Caribbean.


The same specimen as above takes a break on our tent. Man, was this a wonderful campsite (but I digress).


Since this is the first butterfly species chronicled here, I'll throw down with some basic butterfly information. Like all insects, butterflies have three-part bodies (head, abdomen, and thorax) with three sets of legs attached to the thorax. Also like all insects, they have a pair of antennae and compound eyes. In butterflies, the antennae are clubbed. They also have a pair of palpi, which are sensory appendages attached to the mandibles, as well as a proboscis (feeding tube, if you want to be unpretentious). Butterflies, of course, feature two pairs of showy wings as well. As biologists are wont to do, they have further divided the wings into parts, although most of these are fairly self-explanatory. Parts of the forewing and hindwing are described by terms including: cell, disc, tip, trailing edge, base, outer margin, etc. Understanding these terms is important when using a guide, because they tell you where to look for the characteristic features of a given species.


Now that I've thoroughly bored you with bug parts, my work here is done. In other news, I'll be spending the coming long weekend at a lakeside house in New York. I'm hoping to return with plenty of new material.
