Pheidole obtosospinosa gynandromorph. What’s interesting about this guy is that part of its body is from the male caste, while the other part is super soldier. This means that each part has different ploidies, with the male portion being haploid and the super soldier portion being diploid. This strange Frankenstein of an ant is, interestingly, almost perfectly split down the middle. Most gynandromorphs documented tend to only exhibit their dual nature in the head region, tapering back off into one caste in the body.

Born in Petershagen bei Minden, Johann Friedrich Wilhelm Herbst (1743-1807) was best known for joining Carl Gustav Jablonsky in the Sisyphean effort to produce a comprehensive survey of the Order Coleoptera (beetles), an enormous task that resulted in the massive, but still incomplete Naturgeschichte der in-und ausländischen Insekten, 10 vols. (1785-1806).
An energetic and prolific author of essential works in entomology, his smaller Kurze Einleitung (a mere three volumes) attempts to survey the major taxa of what is now considered the phyllum arthropoda, including insects, spiders, crabs, and scorpions. The illustrations are by D. F. Sotzmann.
