Chain of Violence: Study Shows Impact on Palestinian and Israeli Children

Is Chivalry the Norm for Insects?

The long-standing consensus of why insects stick together after mating has been turned on its head by scientists from the University of Exeter.

Instead of dominating their female partners through bullying and aggressive behaviour, males were revealed to be protective, even laying their lives on the line when their mates faced danger.

Previously, scientists assumed that male insects stay close to females after mating to stop them from taking other partners. Female insects have multiple mates and the last mate is most likely to fertilise her eggs. Therefore, by preventing females from taking other mates a male is most likely to father her offspring.
