Since today is informally ParaSaturday (parasite-Saturday) on io9, photographer Marcus DeSieno , best known for his Victorian-style portraits of various parasite species posing like figures of the old West, was generous enough to submit to us his latest: Two Worms Having Sex. Namely, Schistosoma mansoni — blood flukes.

DeSieno, whose photography has been profiled on National Geographic, the Smithsonian, Slate Magazine and Wired, among others, uses a dry plate gelatin ferrotype to give the images their archaic quality. According to DeSieno, "I take the images with a scanning electron microscope, then take that digital file and turn it into a digital negative for the darkroom. That's where I expose it onto a small, tintype plate. The merging between contemporary imaging technology and antiquated photographic processes speak to a larger history of photography and its evolution as a tool, to see the invisible and unseen in relation to science."
