Curtis British Entomology Plate 106: An intriguing glimpse into the complex world of oestrus, a stage in the reproductive cycle of various animals, including horses (oestrus equi), where the abdominal viscera prepare for potential pregnancy. The gadfly, with its ova and larvae, plays a crucial role in this process for many species. Witness the intensity of the African lion in oestrus, a powerful reminder of nature's intricate balance. Insect illustrations from 1823 provide a closer look at the larvae of the ship nasal botfly (Oestrus ovis), while red deer stags, muddy from wallowing, test hinds in oestrus during the rutting season at Minsmere RSPB Reserve, Suffolk, England, October. The strenuous battle for dominance and reproduction continues as African buffaloes join the dance of life.
