copulatory opening造句

• Hepialidae have short, pectinate exoporian, typified by an external groove along which spermatophores are transferred after mating, from the copulatory opening ( the ostium bursae ), to the ovipore for fertilisation.
• Thus, after males produce the spermatophore, they pass an additional gland secretion that spills out of the female s copulatory opening, forming a mating plug that hardens within a few hours of copulation.
• If the male stands his ground and she does not run away or repeat the propulsive display, he approaches and, if she is mature, they copulate, the male inserting the tip of one of his palpal bulbs into the female's copulatory opening, using the first palp that made scraping contact.
