So Pretty!!!!   Yellow - Papilio rumiko - female

So Pretty!!!! Yellow - Papilio rumiko - Female
New Braunfels, Texas, USA

What kind of butterfly is this? Male or female?

However, it should also be pointed out that most of these traits are highly variable in both "species", and they also vary from males to females. In this particular insect (female), the very wide tails with a huge amount of yellow would appear more an "eastern" trait, but the overall insect is quite "western" in appearance. This could also represent the phenotype that occurs along the Gulf Coastal plain and into Georgia and all of Florida, which tends to have a very "southwestern" look about it, particularly in the straight or nearly straight very dark median area of the lower hind wing, and in a tendency toward "stripes" vs. "spots" on the upper head and prothorax in frequent individuals.

Here is a quote from the original description of P. rumiko. It should be pointed out that this could be taken in and of itself as strong evidence that these are actually subspecies of one species that intergrade in Texas (and perhaps adjacent states); it is a matter of interpretation and of species definition. However, more behavioral (and genetic) data would be needed to be sure.
"Due to significant seasonal and individual variation, none of these characters is fully reliable and exceptions exist. The head-neck-thorax line vs. spots (Fig. 11a, A) might be the strongest single character. A combination of characters should be used for reliable identification, e.g., the one shown in Fig. 11E. Many specimens in central Texas exhibit intermediate characters, atypical character combinations, and possible hybrids can be found (Fig. 11E)."

This particular specimen is from central Texas.

Moved from Eastern Giant Swallowtail.

Papilio rumiko?
This image clearly shows a relatively straight margin to the rear edge of the HW median yellow band (what a mouthful), which Shiraiwa et al (2014) emphasize as a key mark helping to separate Heraclides (Papilio) rumiko from H. cresphontes. To the extent it can be seen, the head/thorax also has a solid thin yellow line--another rumiko mark. I'd be interested in other opinions.

Moved from Papilio.


Moved from ID Request.

Most likely a Giant swallowtail and female with that heavy abdomen. Can't see the genetalia at the tip to be 100% sure. Very similar Thoas swallowtail also found in Tx.

state abbreviation doesn't belong in the City field, pls correct
