Breeding

[RobnJocTkeeper]

This may already be in a thread elsewhere. If so my apologies for duplicating information. Question.... what are the best ways to determine if a female T is mature/ready to breed?

I was told they would lay a dud egg sac.

The best way to know is checking a molt. The spermathecae will be sclerotized (darkened looking) in a mature female. Here is an example of mature spermathecae:

0.1 N. incei

• adult female exuviae female holothele incei holothele vellardi incei molt ncf neoholothele neoholothele incei sexing spermathecae trinidad olive tarantula uterus externus

0.1 N. tripepii

6" female N. tripepii.

Awesome thanks, I'll be waiting for another molt then.

Checking to see if the spermathecae are sclerotised would be your best bet (although a couple of my females have surprised me with phantom sacs).
