The African fruit fly is rough in love,
The male uses his organ like a sword;
Its rough edges will cut as it does shove
Into the partner he chooses to board.
Some females have evolved a way to skirt
These unromantic gestures from their kin;
By cross-dressing as males they can avert
The injuries from unwanted lovin’.
The males are darker than their counterparts,
So some females evolved to be more tanned.
And whilst these specimens clearly have smarts,
It only works if others fill demand.
And so some lighter females still exist,
As evolution is a twisted kiss.
This is a Shakespearian Sonnet based on this piece of research, which investigates how female fruit flies have evolved to camouflage themselves as males, so that they are not over engaged in sexual intercourse with their male counterparts, whose sexual organs are so rough that it causes injuries. However, this camouflage only works providing that there are enough non-camouflaged females for the male population.
