B.smithii, how big before sexing?

[Annie3Ponies]

My B. smithii just completed the second molt since getting its "colors". Left me a nice, albeit tiny, exuvium. Before I torture myself trying to examine it under the dissecting scope, can anyone tell me if it is yet old/big enough to tell? Its about the size of a quarter.

I don't know why I care, it is what it is and will continue to be. I am just curious.

It's close, if not now then you should be able to tell in the next molt.

It may be possible if you have a dissecting scope or a magnifying glass at that age. I have not been succesful till they were somewhat larger, but then again my eye sight is not what it once was. But I think you will have to wait till the next molt. Should be a little easier.

I know that Swift over at Swift's Inverts doesn't claim to be able to sex anything under 2", if you look at his site under "free tarantula sexing."
