A black-and-white ink drawing. Realistic headshot portrait of a fence lizard (Sceloporus). Drew this one together with a tiny Lutzomyia sand fly, a parasite that feeds on these lizards. The sand fly is extremely hard to collect, given its size and habit of staying hidden in burrows of other animals. It serves as a vector of Plasmodium mexicanum (a somewhat close relative of the plasmodia responsible for human malaria), a unique Plasmodium that is not vectored by mosquitoes. Curiously, while the lizard population has been shown to be homogenous over tens of kilometres, the population of P. mexicanum is much less homogenous and much more structured, even though it should--in theory--travel within the lizards or in the tiny fluffy flies swept away by wind. This is apparently not the case, as infected lizards seem to move around less and, more importantly, the flies being hidden in burrows all the time means they don't get passively picked up by air currents. If it wasn't for the parasite (Plasmodium) and knowledge of its population data, this extremely sedentary lifestyle of the sand flies would likely go unnoticed.

A small, dark, lizard with dirt all over him, is held in one hand. There is construction equipment in the background.
The face you make when you just got saved from an inadvertent smooshing. #herps #bluebelly #sceloporus #westernfencelizard #constructionmonitoring

A male and female lizard are held side-by-side to compare various anatomical traits that allow them to be differentiated. Male at right, showing swollen bulge just below cloaca, and much larger femoral pores. Coloring also more vivid and widespread across central side. This species are commonly called “blue bellies”.
Side by side comparison of male and female Sceloporus occidentalis. Male at right.
Side by side comparison of male and female. Male at right. Note the much larger femoral pores (little row of yellowish spines at back of thighs) on the male.
Did you know many reptiles have two dongs! Well, hemipenes. And in some species they are covered in spikes and hooks. Anyway, here is a side by side comparison of Western Fence Lizard (Sceloporus occidentalis). Note the hemipene bulges of the male. #herps #hemipenes #herpetology #sceloporus #lizards

This #westernfence #lizard (#Sceloporus #occidentalis) clearly wanted to be showcased today on the 21st of July! As you can appreciate visually, it is a member of the genus #Sceloporus (the #spinylizards). Pic: @JorgeRH2O #JRBPVirtualTour
