I am NOT the voice of experience on this one...but here is what is happening here.
I am attempting to breed a red morph male with a brown morph female.
I have noticed a few 'different' things about the process.
First, although the male has been busy making sperm webs, he NEVER drums, or acts at all interested in the female.
I mated them 3 times before I let them co-habitate (which, surprisingly, they are still doing).
Mating went like this:
they sat there, for approx 15 minutes each time, motionless, no drumming or any other discernable movement. All of a sudden, the male would RUSH over to the female and lift her up. She would cooperate, he would insert both palps, then stretch out as far as he could while still holding her fangs. Then he would let go and make a mad dash to safety. She would try to go after him, and the plastic spoon of justice would stop her
Anyway, there was no equivalent of 'foreplay' with these two. I don't know if that is normal for G rosea, or just for this particular couple.
So far, no eggsac, and they are still cohabitating.
My experience with rose hairs has been some what different... The male that I used with several different females always did the exact same thing... run striaght in, and go for inserts. This apparently worked for him as one of his January conquests has just recently made an eggsac (still keeping our fingers crossed with this one), and he's still alive and well.
