Today’s photograph shows a male [blue] paired with a female [green] azure damselfly in the ‘wheel position’.
In pairing, the male grasps the female’s prothorax with his terminal abdominal claspers so that the two insects form a chain or a tandem. The female then loops her abdomen forward to bring its tip into contact with the accessory genitalia on the male’s second and third abdominal segments. In this ‘wheel position’ sperm is transferred.
