Flying sperm tgp

Description:Science News A man's world: Fruit flies are most active at dawn and dusk but typically rest during the afternoon to conserve energy and reduce damaging exposure to the sun. Male and virgin female fruit flies normally sleep through the hottest part of the day but fly sperm is coated with a "sex peptide" which prompts an intense period of domestic activity in females. The sex peptide is produced in the male's accessory glands - equivalent to the human prostate gland - and its effects last for up to ten days.
