Very nice!
I would say Nephilengys, maybe cruentata.

jeff h is right, it is Nephilengys cruentata.

hi,
no it is NOT Nephila sp. it certainly is Nephilengys cruentata.
BTW.: It will build a retreat above or on one side of it´s web and the web won´t be as large as it is at Nephila sp.
I´ve kept some Nephilengys free in the living room, since they don´t need as much humidity as Nephila sp. this works pretty well.
Also managed to breed the black morph of Nephilengys cruentata 2 years ago.

Mabe You could sex my spiders? I think that I have male and female but unfortunately in the same age. The photos above shows spider with bigger body and in my opinion this is female. Both spiders have the same legs lenght. Please look at second spider (male in my opinion) and tell me if it's true. Both spiders have about four centimeters legs span. How big they will be when they're adult? Second spider's photos:

They are closely related to Nephila.

Both of your spiders are females.

Thank You :)

hi,
from the sclerotized epigynium I would say you´ve got an adult female (maybe penultimate). In any case it won´t grow significant larger.
Males of this species usually don´t grow larger than 5 mm (~ 1/5 inch) BL.
Feed her well and hope for a sac ;)

Anyone else bred those? My female built 5 sacs and only one hatched. Every sac consisted of app. 100-200 eggs and only about 30-40 spiderlings hatched - and believe me I´ve tried everything, different temperatures, different humidity...

WOW... I though that she will be much bigger! Do U really think she will make a sac? I don't know if she came to me from nature or a farm... I have another problem:
why she doesn't make a web? She has terrary 20x20x20cm and she has made only a little web in a corner.. I don't know how to feed her in this situation.

often orbs need air duct to build web ,,, make more ventilations :P
