When it concerns preventing sexually aggressive males, some female dragonflies play dead. Others, according to a brand-new research study, wrestle the males away in midair.
The work issues blue-eyed darners (Rhionaeschna multicolor), a vibrant dragonfly discovered commonly throughout North America. When males of this types wish to mate, they attempt to take the female’s head with an unique anal appendage. If she approvals, the female folds her long abdominal area back towards him and the set flies together in a heart-shaped wheel development.
But if she isn’t in the state of mind, the female starts to tussle, scientists report in Ecology. She shakes her head to attempt to release it from the male, while twisting around to stop him from putting his sex organs beside hers. She’ll even fly backwards to puzzle his efforts. Sometimes, the female will hold tight onto something like a reed to prevent the breeding flight completely, as can be seen in the video above.
If none of this works, the female dragonfly will mess up the flight, dive-bombing into the water to get rid of and for a short while stall the male, who requires numerous seconds to remove once again from the surface area.
