Insects have complex lives & face many of the same challenges we do. Landing a mate, getting along with family, living in an uncertain world..

Anxiety?? In flies??? Sounds weird but flies are a really useful model for anxiety. We share most of our basic physiology & ~60% of our genes with flies. And flies show similar anxious behaviours to other animals (incl us): they stick to the perimeter when they’re stressed.

We wanted to know if anxiety is influenced by mating. Anxiety helps individuals identify risks, & mating might change how risky the environment is.
And mating affects all kinds of behaviours in female insects – aggression, napping, feeding, you name it.

..So we wondered if mating would affect anxiety differently in males and females.
In a nutshell: it didn’t (anti-climactic, I know). No evidence that mating affects anxious behaviour (sticking to the side of an arena). And no evidence for sex differences in anxiety.

We conclude that anxiety isn’t one of the many behaviours affected by mating in fruit flies.
In humans, anxiety is diagnosed 2X as often in women than men. So, we need a different model organism to learn about the underlying genetics of sex differences in anxiety.

Whoops that should be @EleanorBath1 for tweets about flies and aggression
