Just a quick update: No beetles have died since Michael yet. All of the living beetles, including Genghis, are healthy. I can tell them apart because they're in separate containers with their name written on the lid. Almost every container has a pair of one female and a male, except for the male bachelors (Tommy, Imomali, and Ichbinein) and the female bachelors (Alexander who was widowed when Bart died, and Bernard)
