Hi again,

So I always knew how to sex a tarantula by the tibial spurs when the tarantulas mature but I never knew these other ways so I'm learning a lot. Please can someone tell me how old a tarantula can be when you can sex it either through Spermathecae sexing or Epiandrous fusillae sexing.

Thanks

When they hit about 2" you do either way with a small hand lens.

Not all species' mature males have tibial spurs, so that method isn't always accurate.

interesting thank you. Is that 2" including legs? Width ways or length?
