Fancy a drink?

I love the snippets of information that I get on this site!

Sex Quenches Thirst of Female Beetles


In some insect species, including certain beetles, moths and crickets, the males produce exceptionally large ejaculates that can account for up to 10 percent of their body weight.


They found that thirsty females mated 40 percent more frequently than those with free access to water.


Like sponges, females can absorb the water from seminal fluid through their reproductive tracts. The more water they take in, the less frequently they need to mate, an activity that's physically damaging to the females. (The males have spines on their genitalia that puncture females' reproductive tract during mating.)


By delivering a deluge of water with the sperm that thereby also slakes a female's thirst, a male can help ensure his sperm has more time to fertilize the eggs without competing sperm from future mates.


Female beetles mate to quench their thirst, literally.
