I know male mantises live an abbreviated lifespan but I didnt know ghost males live only a month, im assumin they live long than tha....but for most males, two-three weeks after their final molt is when they can be ready to breed
Most of my male ghosts lived a but Longer than that, but I did have 1 drop dead after only a month. I had a couple of males living in a communal tank with females and 1 of them surprised me by connecting to a female on his own after only a week.
Many of these smaller species are a lot quicker to reach sexual readiness compared to some of the other males of larger species that need up to 3 weeks after final moult.
