The Silverlings are a species of mutant changelings that adapt more of their pony heritage thanks to a failed conversion. (This is a fanon species) Their High Queen Belladonna is in charge of most of their breeding and propagation. Like bees or termites the Silverlings will Swarm and create new colonies after their population reaches certain points, thus Belladonna is the High Queen as the original Silverling Queen and the origination of the Virus that created the Silverling Species.
