What's going to happen in a month that didn't happen in the first 12 hours they were confined together? Do you think that after a week or two he'll suddenly start copulating, when he hadn't done it previously? Even under supervised conditions, an occasional Poec male will get killed. That happens with tarantulas. But leaving males in for weeks or months achieves no purpose; basically he's just a future meal kept fresh in the meantime. There's better food for females than that. In nature, he'd get the message when he wore out his welcome and leave, but in captivity he's trapped and can't escape a female chasing him down. Too many Poec males die this way, and certainly too many of mine out on breeding loans.
She also has the old sperm too, which according to your theory wouldn't be as good; it's also going to get on the eggs, maybe fertilize some before the new sperm does. How much sperm do you think a pouch is intended to hold? Gallons? I recently was surprised by 2 normal-sized sacs from females that were paired up over a year ago: a C darlingi and an A ezendami, each paired up one time. That sperm obviously 'kept' just fine. The other darlingi and ezendami I paired up at the same time laid sacs last summer and the females have since molted. From what I've seen, the repeated pairings (ad nauseum) approach seems to be anxious breeders getting themselves worked up over getting a sac of a desired species, and do everything they can think of to make it happen, whether useful or not. In addition to numerous and tedious pairings, I suspect the use of rabbit's feet, wee gee boards, and wearing their lucky underwear also may play a part in the process. Who knows what may work, huh?
I have to think that being moved is a lot less stress then being trapped in a cage with a female hunting him down and ripping him apart. If a male's in there for days or weeks, odds are pretty slim you're going to see a problem in time to do anything about it. You don't usually see aggression with extended pairings, until you see the female eating something that has long legs sticking out.
Not a fair question. Could be calm-before-the storm at any point. They usually don't look stressed, until a few seconds before the female goes after them. And although not a common occurrence, a male Poec will sometimes kill a female (a guy here lost a regalis that way, during an extended pairing).
I have had little issues with leaving male Poecilotheria in with females for an extent of time but here is always an exception. My female P. regalis killed Rick's male the night they were put together. The male from her first sac was almost lunch as well. There will be girls who will not tolerate males and there will be girls that will. Rick is just taking the safe side, which is not a bad thing.
I've lost several males in about 30 Poec pairings during the last 2 years. Unfortunately almost every Poec male I've loaned out has been killed (which has been loans to a number of members, so it's not one person in particular). Seems like a lot of carnage, and that some of it could have been avoided since my losses aren't nearly that high. I think multiple pairings, or one extended pairing, has been involved in most of those. Seems like the thing-to-do with Poecs. And very few of those have resulted in fertile sacs, in spite of the 'good meal' my males provided. I can't see that multiple/extended pairings do anything beyond what a one night pairing does.
