Macro, it is not too late i have had female laying infertile ooth in the past and then producing fertile ooth later on too. Breeding ant mantis is not difficult since male usually gets into action fairly soon when put together. The pair usually connected for only about 30 minutes (short period for mantis) but no worry. She will continue to lay another 8-10 oothecae every 10 days so don't feed her too much until you receive your male. Best of luck! I don't carry this species anymore but remember vividly the ant mimcry of the hatchling is pretty cool. you will like it
