How do you know when a female spider is mature enough to breed? I have a 4.5 inch avicularia metallica(im pretty sure is female.. if someone would confirm on the sexing id thread i would really appreciate it :) ) I know they are supposed to get larger but i read on the breeding reports that a person breed a5 inch female avic metallica. So how exactly do you tell if a female is mature enough to mate and produce a sac. Can females breed before reaching full size?

General rule of thumb is once they are 60% of their adult size, but I personally prefer to wait until they are at least 75%.

Hopefully this will help as well:

Alright, here it is:

There are two ways to access the search tool. From the main page, you can access it in the toolbar directly below your login information (top right corner) and across the length of the site, horizontally:



To access from a sub-forum, it is located below the page select quick-links, on the right:



With either method, click it, and it opens a text box to insert search criteria:



You can type the criteria and click 'Go', and that's that. If you would rather do a more advanced search, click the 'Advanced Search' link.

Advanced searching

Here's the advanced menu:



If you are already in a subforum, it will highlight it and only search through there. To change the forum you would like to search, just scroll and click the proper forum.



To select whether you want to search all posts or only titles, use the drop-down box just below the keyword(s) text box:



And finally, if you are searching for multiple words and would like them all to appear in your search results (as opposed to only one or two of the words appearing), be sure to put quotes (" ") around the words. For example, if you are searching for 'pine bark', you will get results with the word 'pine' only and 'bark' unless you put it in quotes ("pine bark").

I hope this is helpful to everyone.

Thank you xhedex very helpful! I would have never thought they could breed at such a small size amazing! Are there potential health risk at breeding at 60%? I did try the search function but a ton of unrelated stuff came up. Maybe I just was not using the words I needed?:wall:

I like to check the females spermathecae for signs of darkening. As a female begins to mature each successive molt you will notice darkening and hardening of the spermathecae. Under microscope, immature spermathecae are relatively clear (sometimes so clear you cannot even see them, you have to use an implement such as a pin) to "lift" them so they are visible. As a female begins to age, the spermathecae will begin to develope small, reddish dots and each molt the dots will increase. I personally will attempt a mating when about 50% of the spermathecae is covered in the dots. At full sexual maturity the entire spermathecae will be darkened.
