Vampire literature has a rich history, dating back to ancient mythologies and folklore. Over the centuries, the depiction of vampires has evolved significantly, from bloodthirsty monsters to complex characters with human-like qualities, desires, and sometimes, erotic appeal.

The nocturnal mating practices of modern European vampires remain virtually undocumented in the scientific literature. This paper reports the results of a mixed‑methods field study conducted between 2021 – 2024 that investigated the temporal distribution, behavioural cues and sociocultural framing of the phenomenon colloquially known in German‑speaking regions as “Vampire Ficken um halb eins” (literally, “vampire sex at half past one”). Using a combination of infrared videography, biometric monitoring, and semi‑structured interviews with consenting participants, we identified a statistically significant peak in copulatory activity centred on 00:30 ± 10 min (German “halb eins”). The findings suggest that this temporal clustering is mediated by a complex interaction of circadian hormone cycles, lunar illumination, and ritualised cultural scripts that have persisted since the early modern vampire folklore. Implications for the broader understanding of non‑human chronobiology and the integration of mythic species into contemporary sociomedical frameworks are discussed. new moon) | +0
