My friend got a female rosie 15yrs ago. She was mature when my friend bought her. You know how LOOOONNNNNGGGG those darn rosies take to grow!
Thats something i have been wondering about as well, how do you guys determine adult, sub-adult, juvenile and sling? Does it have to do with instar? Thats the only compareable thing that comes to my mind or is it just a rough term referring to size? In males it schould be easy enough to tell if it reached majurity but apart from seeing adult bits in the exuviae i cant even beginn to guess how to be certain in females.Unless you know the date the tarantula was hatched, there is no way to know or even estimate its age. Too many variables affect the growth rate. And as you state, sub-adults and mature tarantulas look pretty much the same. Sub-adults may be a little smaller, but again, unless you know the hatch date, size will not give you enough information to estimate the age.
I consider them slings until they get juvenile colors.Thats something i have been wondering about as well, how do you guys determine adult, sub-adult, juvenile and sling?

Wow, pretty cool 19 years.One and All -
Some of you may remember the story of the Duchess, the big Brachypelma emilia (Mexican redleg) that appears on page 31 of The Tarantula Keeper’s Guide.
We bought her in July 1972 from an animal importer in Ann Arbor, Michigan. At that time she was large enough that we’re certain she was full grown. As a crude estimate, we think she was at least 15 years old at the time, probably older, possibly much older.
She finally died for us in January 1991, almost 19 years later! Her total life span was probably in excess of 34 years.
We still have several Brachypelma smithi (Mexican redknee) that were imported just before they were put on CITES Appendix II in 1985. They were full grown adults at that time, at least 15 years old. That would place them at 35+ as I type this.
How much longer will they live? We have no idea. We do know that several of them produced eggsacs about 3 years ago that were destroyed by Phorid flies before the eggs could hatch. Thus, at least some of them are still fertile.
In our experience and from watching many others, this tarantula keeping thing commonly develops a lot like this:
At first you're fascinated by them. They're so bizarre and many of the New World kinds, at least, seem to be so cuddly and friendly. (Once you learn to tolerate the bristles!)
After a few years you begin to get bored of them. (Oh God! You still here? When are you goin' to die?)
After a few more years, if you can stick it out, you begin to realize that you've been popping crickets into their cages for YEARS now! Maybe more than a decade! "Good grief! That thing's older than my kid!" is a common remark.
At that time you begin to really appreciate what they are. You begin to treasure them like a fine Renaisance painting or a 1914 Stutz Bearcat.
Ten years is nothing. When you write them into your Last Will and Testament, you can start bragging!
