Magnificent swallowtail

I thought you were in the middle..., meaning in the middle of nowhere, if you take E, W, N or S.

Actual taxon is Pterourus garamas.http://www.butterfliesofamerica.com/L/pterourus_garamas_abderus.htm Papilio is, however, not wrong...

I would leave it as Papilio garamas. I was in Mexico myself, but still have NO idea about the geographic/lepidopteran borders. Where is East and West and where is South and North and if you are in the middle, where are you actually?? ;-)... BTW: Obviously this one is now called Pterourus garamas. I do not now why there are 2 links for the same from BOA, one with Pterorous and the other with Papilio. Kim Garwood has it also as Pterorous garamas. http://www.neotropicalbutterflies.com/Site%20Revision/Pages/Swallowtail%20pages/Pterourus_garamas.html Again Tamaulipas is in the North, so yours is probably not Abderus. http://butterfliesofamerica.com/t/Papilio_garamas_a.htm http://www.butterfliesofamerica.com/L/pterourus_garamas_abderus.htm My previous link in the other one is definitely from the North! http://www.naba.org/chapters/nabast/garamas.html

Papilionidae, Papilio garamas, can't tell you the subspecies. Too many around and too many overlappings. http://butterfliesofamerica.com/t/Papilio_garamas_a.htm

Beautiful!
