New Mexico whiptail
An all-female lizard species that reproduces without males.
The New Mexico whiptail (Aspidoscelis neomexicanus) is a female-only species of lizard found in New Mexico and Arizona in the southwestern United States, and in Chihuahua in northern Mexico. It is the official state reptile of New Mexico and is one of many lizard species known to be parthenogenetic, reproducing without males.

Lore & Background
The New Mexico whiptail is a hybrid species resulting from the crossbreeding of the little striped whiptail (A. inornatus) and the western whiptail (A. tigris). This hybridization prevents healthy males from forming, leading to an all-female population. The species reproduces through parthenogenesis, with females laying up to four unfertilized eggs in mid-summer, which hatch approximately eight weeks later.
Reader's Guide
The New Mexico whiptail is significant as a natural example of parthenogenesis in vertebrates, a reproductive strategy that allows an all-female population to persist. Its existence through interspecific hybridization and parthenogenesis is shared by several other whiptail lizards in the genus Aspidoscelis. The species has also gained cultural attention, being dubbed the 'leaping lesbian lizard' and considered a gay icon in online LGBTQ+ spaces due to its all-female makeup and observed mating behaviors between females, which are thought to stimulate ovulation. As the official state reptile of New Mexico, it represents a unique biological and cultural symbol.
