- In successful matings, the time of the first palpal insertion and which palp was inserted were noted.
- Males were allowed only one palpal insertion with each mate as males are functionally sterile after each palp is used once, but sufficient sperm is transferred in a single copulation to fertilize all of the female's eggs.
- And if you're more interested in how arachnids do it with palpal specializations than molluscan harpoons, I've got an article on how spiders mate.
