They are easy to mate but you have to put them in proper housings. Females are much better hunters than the males so you'll want to put them in smaller housings like a 4 x 6 x 8 tupperware. As well, the males like eating winged insects...houseflies are perfect for them. Crickets freak them out.
The males are good to go literally right after getting there wings....but the female you will have to watch. If you see the tip of her abdomen kind of open up while her antennae are freaking out...she is ready. This is how she puts out her pheromones.
Get a storage bin or a box, get a branch (I use a deer horn) and strip off the leaves, hopefully it will have a few smaller branches connected to it so you can angle it upwards. Put the female on the branch, then gently put the male in with her about 10 inches away. Take a pencil and lightly tap her on the tip of her wings...once she starts walking the male will instantly see her and approach. He might wait an hour and most likely will mount her backwards (males are idiots) but she will let him figure it out and not kill him. Most of mine stay locked for 4-5 hours.
If he hestitates, just lightly blow on him (straw) and he'll do what needs to be done. Why blowing on them works.....I don't know. I have never lost a male to mating, after they are done remove the male, put him on a houseplant and give him a good misting..he'll be thirsty. For some reason my females love a good cricket after mating....go figure.
You may be able to get a second or even third mating out of your male or he may just die. In any case, 2 males, mate her with both just to be sure the job gets done. I generally release my males after I mate them.....they did their duty and should go back into the wild.
