Just wondering... When breeding or buying slings what’s the male/Female ratio?
Very good question, I wonder if someone has a solid/scientific answer for it as I would love to know for sure myself. I would imagine a 50/50 ratio would make sense but then again my answer is not based and data. This said if you want to see more opinions I found this old thread from arachnoboards: https://arachnoboards.com/threads/s...text=What it means is there,%male, 50% female.Just wondering... When breeding or buying slings what’s the male/Female ratio?

Sounds like the perfect and quite valid justification to buy a lot more Ts. Let's see if I can swing this by the wifeUsually, if you buy slings and want to obtain a higher chance of getting a female, I would buy at least 4. You can always buy more (if I find a deal on 10 lots I will usually buy those and you're almost guaranteed a female in a 10 lot but nothing is 100%). I'm unsure of the ratio of male/female in sacs. I suppose it varies by genus, locality, environmental factors, etc.
It's just pot luck in the end with spiderlings unlike buying "unsexed" sub adults and large juveniles where there is a 95% chance it's male.
Wow. That sucks. If sacs are indeed 50/50, you had a 1.6%chance of getting all male, mate!I don't think anyone has ever actually done a proper study of the sex ratio of tarantula spiderlings. I've read a couple of papers on other spider species and from what I remember, based on multiple sacs, it was pretty much a 50/50 split. Sometimes the sacs had a higher male ratio and sometimes they had a higher female ratio. I've often seen this ratio of 3 males to every 1 female being touted for Omothymus violaceopes ever since they were first introduced into the hobby but I've never seen any data to actually back this up.
When it comes to buying slings then obviously the more you buy the greater the chance you have of getting a female. However saying that, I remember getting a colony of 7 Poecilotheria formosa slings from Ray Gabriel and all 7 turned out to be male . It's just pot luck in the end with spiderlings unlike buying "unsexed" sub adults and large juveniles where there is a 95% chance it's male.
Awesome Clownie. I know your data is sparse, but you do offer data. Thanks!Only the spider gods know. I've done a few hold backs with my last few sacks ive pulled or lots purchased. Here are the results....
30 Tliltocatl sabulosum 13.17.0
20 Poecilotheria ornata 12.8.0
12 Hapalopus sp. columbia 7.5.0
15 Alphonopelm Seemani 1.14.0
10 Poecilotheria metallica 9.1.0
5 Ceratogyrus darlingi 2.3.0
12 Psalmopoeus cambridgei 7.4.1 (1 death unsexed)
5 Poecilotheria rufilata 0.5.0
I agree with you there.. I think we've all been duped at some point buying 'unsexed' or 'suspect females' from sellers who know full well that they are male - buying slings is the most enjoyable part of the hobby for me and its lovely watching them grow on if they turn out to be male not so bad as we always try to put MMs back into the hobby whenever possible if possible always get as many slings as possible to up your chances.. . Why not?
Couldn't agree with you more about enjoying keeping the MMs and about people letting them wither away - it's such an waste, put your MMs in the hobby for the hobby sake and breed so more can enjoy the Ts...Im kinda disturbed thinking people let the males just wither away. I personally have financed my entire hobby in the last 38 years from male spiders. I actually enjoy the males as much as the females...maybe more?
