Psalmopoeus irminia. Venezuelan sun tiger

I thought it was about to happen and it did, my P.irminia tarantula sling has molted again. This is about the third time it has molted since I have owned her/him. It started about the size of my little finger nail and is now about 3 or 4 cm in size.

It is now starting to look a lot more like this picture but its still not know if its a male or/female, things can change.

I am really hoping it will be a female as she will look just like this one, if its a male it will change quite a lot and not be quite as striking. In fact it will go a more grey/silver colours.

One of the main differences between male and females is that in most (if not all) live for different life spans. Males generally do not live as long as females and often the difference is quite substantial.

So the male looks quite a bit different although it is still a great looking tarantula.
By choosing to grow on tarantula slings it is impossible to tell the sex of the spider at such an early age. So its really 50/50.

Out of our seven tarantulas four of them are slings and three are young adults. from the adults we know that the Avic Avic is female, the B.smithi is male but we don't yet know the G.rosea as she hasn't molted since we bought her a year ago and she/he came unsexed.

So we just don't know the sex of some of them yet but if I could get to the molt of the P,irminia maybe I could sex it, but getting the molt now thats easier said than done ! this is one quick tarantula.
