Social insects like bees and ants are excellent mascots for public health because due to their densely populated nests insects invented some of the fundamentals of "public health" long before humans even existed.
Ants famously have grave yards. It's fun to imagine this is because they are sad about their fallen sisters and wish to remember them, but the real reason is much more simple: dead ants can be vectors of ant pathogens, so it's important to isolate the dead bodies.
