My Red Runners Having Babies Without the Males?

[Aragorn]

I looked over my Turkistan roaches' bin and I see some females and small nymphs, which I have never gotten after the first batch! The weird thing is: I haven't seen any adult males, which have wings. All I see are smaller immature or females, but they seem to be producing oothecae without the males and I see tiny little roaches running around everywhere. This is the first for me. Either that, or in my colony my males have no wings. It can't be from the first batch I got because that was a long time ago and all the nymphs have grown quite considerably and I see oothecae everywhere, but no males.

Has there ever been a male present? Like, within the last 6 months? I've heard that it may be possible for subadult females to mate with adult males and retain the sperm until adulthood.
Reportedly, Blatta orientalis, a relative of Shelfordella lateralis, can reproduce parthenogenically, or without males.

The persons I got them from has an establish colony, so they were probably kept with the males, yes... But not in my colony.... I've looked everywhere for the males in my colony, but I could not find even one.

Just one successful mating is sufficient for the female to continually lay for months.
