Darkening Psalmopoeus cambridgei. Thanks, Anastasia for sending me the daddy.
I finally got one of my own Tapinauchenius subcaeruleus females to reproduce. There aren't many, but fortunately I got 1/2 a sac from Anastasia's female.
And...I also found this Avicularia azuraklaasi sac when I got home from work. The male is still in there with her, so I need to get him out of there, I guess. Diane
