Just be thankful your not a female fruit fly….
Normally flies sleep at night and then have ‘siestas’ during the day. However scientists saw that female flies had different behaviour.
It has been shown that after female Drosophila melanogaster are mated they become more active. After investigation (including cauterising and castrating male flies) it was found a sex peptide in the semen caused this raised activity - the females become more domesticated, looking for places to lay eggs, preparing for birth and producing up to 100 times more eggs for up to 8 days. This causes females to have shorter life spans! They literally work themselves to death.
To me, this seems a little unfair.
