so i bought some european mantis ooths from a local nursery to throw in the garden. one ooth hatched today but there were only about 12 mantids in there. question is whether it is possible for the others to hatch out within a certain amount of time. i also have a ghost mantis but i dont have any experience with ooths. thanks.
