This Is What Happens to Mosquitoes in the Winter

The greatest thing about winter is the lack of bugs. No pesky mosquitoes making you itch every time you go outside at night! It’s such a relief — but, like, what even happens to mosquitoes in winter? Do they fly south, like birds?

Not quite, according to Mental Floss.

Mosquitoes have difficulty surviving in any temperatures below 50 degrees Fahrenheit, but their strategy depends on their sex. Males simply die off, though not directly due to the cold — instead, the winter just happens to coincide with the end of their life cycle, when they’ve already finished mating. They actually only live for about 10 days anyway.

Females, on the other hand, enter what is called diapause, a rested state similar to hibernation. They find a hollow log to burrow into, slow their metabolism, and hunker down until the cold is over. Females can stay in diapause for up to six months, thanks to the large reserves of energy that they hoard beforehand — they eat up to 10 times their normal body weight in blood to prepare for this stage.

After warm weather returns, females leave their burrow and return to their normal metabolism. Then they must search for more food (blood) to nourish their eggs, and the whole dreadful cycle starts all over again.

Unfortunately, there are some exceptions to all this. Some types of mosquitoes can actually breed underground in the winter and forego food, allowing them to stay alive all throughout the cold months. A species called Culex pipiens molestus invaded a poor Manhattan neighborhood in exactly this manner.

Bummer.

Gorillas like to Sing “Little Food Songs” When They Eat

Now this is a story we can all get behind!

A German scientist at the Max Planck Institute for Ornithology who was working in the Republic of the Congo recently reported that gorillas hum and sing while they eat.

Yummy songs, if you will.

Eva Luef, primatologist from the institute based in Seewiesen, Germany, studied two families of western lowland gorillas in Congo, and identified the two types of sounds.

While calls regarding food have been observed from chimpanzees, this behavior has never before been officially recorded in gorilla study.

Two different types of sounds have now been observed coming from dominant silverback males at meal time. One is a low hum that may show contentment or happiness. You can listen below:

The other sound–a short series of notes like a song–may be used to call other members over to the food. You can listen below:

Since the males are the leaders, they are the ones that call family over for dinner. It appears to be the males’ way of holding on to their females and keeping them fed and happy. Luef also observed the songs are made up by the big males for each meal time, rather than being the same tones repeated.

More chimps make the nom-nom sounds–not just the dominant males. This may be because chimpanzees have a much more fluid society when it comes to who hangs with whom.

Researchers think they may have found a clue into how language among humans evolved. Because of the variation in the songs, food calls may have been a start to the way early humanity communicated.

Because no species can evolve on an empty stomach.
