I've done more ooths before.
It can get a bit hectic, but with 20 of the ooths being native species, most will be used to populate my area. Some of course will be kept as pets, and for breeding purposes as I plan to make the species more available (seems in some native areas they are dying out), with a few offered for sale so others can reestablish the Carolina species in their area too, as I have sold many ooths for that purpose already.
I prefer to gather the ooths and adult females from outdoors before winter - allowing the adults to live longer lives, and they produce more ooths. That allows allow me to breed them too, ensuring their ooths are fertile. Also it prevents the common local parasitic wasps from destroying so many eggs in the ooths, and other dangers. Basically it is a just a small scale attempt at preserving and boosting the mantids in my area.
