A study was conducted of the reproductive cycle of the dung beetle 𝐵𝑙𝑎𝑐𝑘𝑏𝑢𝑟𝑛𝑒𝑢𝑠 𝑠𝑎𝑦𝑙𝑜𝑟𝑒𝑎, found on the eastern slope of the volcanoCofre de Perote, Veracruz, Mexico. The reproductive system of this species is similar to that of other species of Aphodiini. It is a multivoltinespecies, reproducing throughout the year under terrarium conditions, as it does in the wild. The life cycle of this species lasts about 45 days.Females lay up to 8 eggs in a chamber located below a dung pat. Preimaginal development lasts about 25 days. Stage 1 larvae go up to freshmanure and develop to stage 2; at stage 3, the larvae return to the soil, pupate and become imagos. Young imagos become sexually matureat between 5 and 10 days following emergence and the subsequent reproductive period lasts about 10 days, after which they die.
