The dragonfly will die to avoid being bullied by the male

Scientists have found that dragonflies are often fake to avoid being bullied or forced to mate.

Scientists have found that dragonflies are often fake to avoid being bullied or forced to mate.

We know that dragonflies can do some amazing things during their survival, such as flying away or predicting the movements of prey to kill them quickly. Recently, a zoologist continues to discover a special behavior of females in Aeshna dragonflies .

A study recently published on April 24 shows that dragonflies tend to create a scenario of an accident to prevent males from flirting and soliciting.

Rassim Khelifa, a zoologist at the University of Zurich, went to the Swiss Alps to conduct experiments to see how environmental temperatures affect larvae. During the experiment, Khelifa witnessed a dragonfly being chased by another on a pond. The child was suddenly thrown to the ground and lying motionless. The other one hovered over for a while before flying away.

Dragonflies tend to create a scenario of an accident to prevent males from flirting and soliciting.

Khelifa recounted: "I think the dragonfly could die or be seriously injured after landing like that. However, it surprised me to quickly fly away later."

Surprised by what he saw, Khelifa wondered if this was the scenario the children created to avoid mating? To clarify this, he was watching the dragonflies for months to come.

Months of observing dragonflies made Khelifa realize that the incredible scenario he witnessed was really popular among the children of A. juncea species. To understand why this phenomenon occurs, zoologists have considered the reproductive behavior of the species.

He discovered that wandering males were just waiting to coerce the mating females and then leave, leaving the females hurt when they lay eggs. This is not the same as other dragonflies when males can stay to protect their females when they are born.

He found that many males flew patrols in the area to wait for a mate and this increased the risk of more children dying. However, not every child succeeds in pretending to be dead. Of the 27 unmoving females, 21 (77.7%) succeeded in deceiving males with coercive intentions.
