Flaboon

alien spider things. Found once on the wild west planet. Empire has established a trade relationship. They Terraform planets and then extract minerals. Eventually they lay eggs in a volcano and those eggs are exploded into space to repeat the process. They have a loose federation called the Flaboon Network. Only B Team contact has been Hermia and Pax on the wild west planet. They are strongly psychic and psychically enslave locals of planets they attempt to terraform.
