Success! I tried to mate them last week, but it wasn't happening. The male would get on her but wouldn't do anything. He was only about a week into adulthood. So I tried again this week and it happened. Friday night, 6pm I put them together, an hour goes by with the male not doing anything but chilling on her back. I come back to check on them and I see them connected, but about 30 minutes later, I see them disconnected. At 11pm they were still disconnected. I decided to check on them one last time before heading to bed, there were connected! I wake up to find them still connected. I leave to run some errands and by the time I got home around 2pm they were done. I don't see the male, but I also don't see evidence of him being eaten. I hope he's just hiding in my room somewhere. I mate my mantids out in the open so the male has a better chance of escape.
