English: Ceriagrion cerinorubellum is a species of damselfly in the family Coenagrionidae. It's commonly known as the Bi-coloured damsel or Orange-tailed marsh dart.
Prior to copulation, male odonates transfer sperm from the genital pore on abdominal segment 9 to the accessory genitalia on segment 2 (intra-male sperm translocation), a type of behavior peculiar to this order of insects. Corbet (1963) states that the time of transfer may vary between and within species, and lists the following times in the reproductive sequence when it may occur: (1) in the unpaired male (before approaching the female; (2) after the male grasps the female with his legs, but before doing so with his abdominal appendages ; (3) after the male grasps the female with his abdominal appendages (tandem position); (4) in more than one of the preceding. (Ref: doi:10.1093/aesa/58.4.592, doi:10.1371/journal.pone.0009904, Corbet (1962) Biology of Dragonflies)
Most damselflies do it just after grasping the female (3. in tandem) as shown here. Polski: Para ważek z gatunku Ceriagrion cerinorubellum w czasie, gdy samiec przenosi spermę z podstawowych narządów płciowych znajdujących się w 9. segmencie odwłoku do narządów pomocniczych w 2–3. segmencie. |
