How long ago did she lay? She still looks gravid to me. The gravid colors should fade away 1-3 after laying. If she stays that coloration for any longer, put her back in her laying bin (or whatever you used). She may have more eggs inside her. They dont always lay them all in one sitting. Goodluck!
Crickets are pretty easy to breed. There is a little labor involved and you have to keep on a schedule to always have them. Once you have it down its pretty easy. Ive been breeding them for the past 4-5 months and Im kicking myself for not doing it sooner.
Hey man you can keep it. There not native or endangered or anything. Really there a huge problem that keeps spreading north and south conquering the sidewalks, getting in my screen porch and climbing all over my cham cages trying to eat anything that moves. So again just keep it if you like it...
From Africa? Tanzania? Photo or scientific name please, but I think I know what your talking about. If there what im thinking, they pop up every once and a while.
