Please don't hate! I couldn't get my pictures to post in the ID section.

This is my Chaco Gold Knee. One year old...about. Male or female?

I forgot...I have two separate cameras. One is broken and frozen in time...Please disregard the first picture's date. Both pictures were taken this week.

Read this ( http://www.birdspiders.com/_images/sexing.pdf ) and then take a guess.

If you have more time read where that pdf came from too http://www.birdspiders.com/faq_sex.php[/QUOTE

The link you responded with means nothing to me because I don't know what I'm looking for.

That link tells you what to look for and if you don't want to read just look at the two diagrams in the lower right and compare to that first picture.

Abdomen size has nothing to do with the sex ever, and the palps of a immature male look just like that of a female.

Also I'm curious as to where you got one year old?
I think these links should definitely tell you what to look for. Here's another http://tarantulas.tropica.ru/en/node/586.

I'm no expert but the little circular patch of darker hair in between the two front book lungs would make me say male. Again, I may be completely wrong.

Seems female to me, based on what I think are spermathecae. Could be mistaken, though. I'm not very practiced at ventral sexing, to tell the truth.

Those are on the inside. This spider is very much male.

I remember reading (I don't remember where) that the small circular patch of "hairs" are actually mini spinnerettes that aid in the making of a sperm web. Correct me if I'm wrong, confirm it if I'm right...

See? Complete doofus. Using the wrong terminology for parts that aren't there. Haha

I've never heard this but I'd be interested in an article stating it.

I vote male. The dark patch on the ventral photo is a dead give away.

TKG pg. 262. Just found it.

"Arachnologists have noticed in immature male tarantulas, this are has a central patch of bristles with a color, luster or sheen different from those that immediately border it. This is actually a small patch of special silk glands used in the creation of the sperm web" (TKG, Schultz and Schultz).

I should also state that by "this area" the writers mean the following. "Immature males may develop a telltale clue to their sex by the appearance of a small patch of bristles, the epiandrous fusillae, on the epigynal plate of the opisthosoma several several molts before maturity." (TKG, Schultz and Shultz) I hope Stan doesn't get upset by my quoting directly out of his book.

One of these days i'll finish reading it....thank you for the page number though I'll go pick up my copy.
I read the 1998 version cover to cover but I haven't finished this one either. I just shoot around. I mean to finish it but then I get caught up in Harry Potter and forget :p
