Palpal bulb must be inserted during mating correct?

[Ramen]

I have a friend saying that he witnessed his rear horned baboons pairing but did not see the male insert his palpal bulb into the females epigastric furrow. He only saw the male "drumming" on her area with his pedipalps. This is a failed breeding attempt correct? The male simply cannot rub his palps on her parts, there needs to be insertion?

Depends on what he thinks he saw. Drumming is one thing, but their needs to be insertion.

maybe it happened and he didnt see it.

in doubt, try again.

He didn't see insertion and tried to pair several times after the attempt and the female was not receptive to it. I wonder if maybe it was a success somehow, but I doubt it. My friend swears he didn't see insertion.

 

[A guy]

If the female was receptive the first few times and then was just suddenly not, then an insertion happened.

Regardless of all of that, it wouldn't be possible for the female to ever be gravid by just rubbing the palps on her furrow, correct? There needs to always be insertion right?

so what about phantom eggsacs?

so what about phantom eggsacs?

Those are not fertile eggs. I believe they're talking about fertilized eggs here. And yes, for eggs to be fertilized the sperm needs to go where the eggs are, which in this case is inside the female spider. That's basic biology.
