They're generally called vinegar flies, and they don't infest fresh fruit like fruit flies do when they lay their eggs in fruit.

Ok let me introduce you to the barn owl

But they do? Along with any other animal that happens to be nearby.

That is the one insect I will go out of my way to kill.

Without a lie they'd just be horsefs

No it's because they take a horse sized chunk out of you when they bite you

Don't you drive a car?

There's even the old Marx brothers joke "time flies like an arrow; fruit flies like a banana"

The fruit fly trap taught to me by an entomologist friend is baited with wine, suggesting the fruit flies want fermenting fruit

The trap: get a plastic fizzy drink bottle; bigger is better

Cut off the top. The cut piece is a cone

Place the cone (the top piece) upside down on the rest of the bottle

Sticky tape the joint

Bait with cheap wine or leftover wine or beer. The bait is poured down the funnel into the trap

Her tastes were revealed in the description of baiting the trap — she specified red wine, but I have tested with various booze and fruit flies have no taste, they'll go for anything. You could probably extract bait from the sourdough starter you made in lockdown and kept alive despite never making bread after that first try

The fruit flies you've seen eating fresh fruit are probably Drosophila suzukii (spotted wing fruit fly). Most (all?) other Drosophila species (including the model organism Drosophila melanogaster) only feed on rotting fruit. Though they'll consume the sugars too, not just the microorganisms. So standard lab diets include sugar along with yeast and often cornmeal.

There are also some more distantly related flies that feed on fresh fruit and are commonly called fruit flies, eg Ceratitis capitata (Mediterranean fruit fly)

I’m sure the meme is apocryphal, and it’s not entirely correct. Fruit flies do eat yeast, yes…but they also eat the sugars in the fermenting fruit, not just the microorganisms causing fruit decay. I don’t know about the larvae at all, though.

Mosquito hawks do not, in fact, eat mosquitos.

I no longer respect those annoying fuckers.

Emperor penguins and king penguins are not descendants of any royal bloodlines and do not have an understanding of monarchical governments.

Nah, it just trips into the future

Someone tell this guy about Jeremy bearimy and timey wimey space stuff

A man in a very tight suit with a blue box once told me it's more wibbly-wobbly.

W wait a s second! What do sperm wales eat? Have I been pointlessly jacking off into the ocean for decades??

Earthlings don't eat earth because "earth" isn't something to be eaten. Sperm whales don't eat sperm because sperm is (usually) not something to be eaten.

Fruit, however, is supposed to be eaten, and by many, many animals. By calling something a fruit fly, the expectation for most people would be that its diet consists mainly of fruit

Dobsonflies don't even eat Dobson!

What a world
