The "Galactic Parasites" event in Stellaris — flavor, choices, and how to trigger it with the event console command.
Galactic Parasites

… is under attack. A large group of Voidworms is in orbit of the colony, bombarding it with parasitic cysts. Each cyst contains a toxic spore that is extremely deadly not only to our colonists, but all life. Once ingested, it rapidly gestates into a nymph that will emerge violently and completely destroy its host. These nymphs contain a bladder of compressed gases that allows them to ascend the upper atmosphere, where they instinctively propel themselves to a predetermined destination. Biological analysis indicates that each clutch of Voidworms has a limited supply of these cysts to distribute, and it is likely they will depart once all are depleted. Until then, we are suffering significant population loss.
