Here's why fruit flies love your wine as much as you do

Ever wondered why a great bottle of Shiraz attracts fruit flies?

Here is why the pesky creatures have an intense sense of smell, according to The Naked Scientist, Chris Smith.

The antenna on the flies are decorated with nerve endings which have these chemical receptors on them for the very same volatile agents which are given off by wine - because these flies would normally track down fruit, rotting fruit and fermenting fruit that dropped on the floor. They go and drink the sugar that is being released by that fruit, they lay eggs on that fruit and more fruit flies are born.

Chris Smith, The Naked Scientist

Their nervous system is programmed to detect those chemical at very very low levels and they can smell these things from very great distances away.

As soon as they pick up that smell they think that is lunch. That is my chance to meet some other fruit flies, make sweet fruit fly love and lay eggs. They're looking to do that in your wine because they think the wine is fruit. Because at the end of the day it was grapes.
