5 Fun Facts About Fruit Flies

Am not I

A fly like thee?

Or art not thou

A man like me?

(The Fly, William Blake)

 

  1. Fruit flies can’t stand carbon dioxide. It makes them woozy and unfocused.
  2. Fruit flies’ chromosomes look like barcodes.
  3. Fruit flies have 100,000 neurons, which is a very high number for flies and it is this large brain matter that makes fruit flies so intelligent.
  4. Fruit flies love their beer and males often get drunk on both alcohol and fruit. Female fruit flies have been observed rejecting males who get drunk often. (here’s an addition: humans like the same beer and wine as fruit flies…go figure)
  5. Fruit flies enjoy sex as much as the human whose house they are in. Turns out sexually-deprived males go into depression and look for alcoholic drinks/food, while their sated counterparts steer clear of alcohol. 

 

Bonus

Fruit flies are a boon to science. They have a whopping 14,000 genes in their bodies (humans have 24,000…so that should tell you something) and extremely fast life cycles (fruit flies can  mature from eggs to adults in as less as two weeks), which makes them perfect for genetic experimentations. In fact, fruit flies have contributed to 6 Nobel Prizes between 1933 & 2017.

So, what did fruit flies help us understand?

  • Role of chromosomes in heredity
  • Role of radiation in genetic mutation
  • Control of embryonic development through genetic experimentation
  • Role of the olfactory system
  • Activation of immunity in organisms
  • Molecules that control the circadian rhythm
  • Mechanism of cellular healing in severe wounds
