I thought these spiders were murderous with their mates... This is not the case... I tried mating my cobalt blues and the male jolted into the females burrow... I got my red light and watch the action take place then... nothing... the male stayed in the burrow with the female for 3 days and he is still there now... I am so confused. I tried to coax him out thinking it was a fluke but he went deeper next to the female and nothing... my female is perfectly healthy and full of mad energy as she slayed a large male dubia the day of the day of their marriage. This is weird... there is no aggression with these spiders... perhaps cobalt blues can also live communally or in this case "as a couple". Perhaps it is just spider love hehehe if you have any explanation or fore thought please let me hear it.
