how common are females?

[L4M4R]

Is it a 50/50 or are there more males in an eggsack? Anyone got any 411 on this subject?

This is one of those questions similar too, how long is a piece of string?

From my understanding there's no set formula for M:F ratio.

If you want more chances of a female do as most do an purchase multiple slings of each tarantula you're purchasing, that way your more liable to end up with a female.

Why would they be 50/50, humans aren't. It's going to vary with each spider's situation and the distance and risks that males encounter. It's like asking how many eggs is a sac, how big the babies are, and how fast they grow. It's all over the map depending on what works for that species.

I wonder if incubation temperature has any effect on the ratio, like with reptiles.

Yeah it's Very Very unlikely that an eggsac would produce 50-50, in my experience thairs usually more males than females.

this is ultimately why I get more than one sling of the same specie in order ensure I have a female. it will ultimately vary for instance I have six H.albostriatum sling, four mature into males, while the other two seem to be female. however I have 10 sub adult H. lividum and only three have mature into males so far.

thank you for being the only one to answer my question using common sense. I'm wasn't asking exactly how many males there are in an eggsack. My question wasn't at all far fetched and i always have to rephrase because of sarcastic people .

this was also very helpful thank you.

Seems that way with the spider I've had too, but there are species where males are rare. It's going to vary with each species. With 900+ species in many different climates all over the world, there's not going to be a lot of similarities in many things about tarantulas.
