time flies like an arrow, fruit flies like a banana

[–] SerpentPeaked@lemmynsfw.com 82 points 3 days ago (8 children)

What other lies have we been told? Does time not fly like an arrow?

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

Gray Knights have been dispatched to your location, please stand by.

Awesome, this daemon infestation on my computer (Gentoo of course) is really starting to annoy me.

[–] Demdaru@lemmy.world 16 points 3 days ago (1 children)

Better yet, they aren't actually penguins - they were just called that because they resembled real penguins.

Which are literally dead today, because they dared live close to humans.

[–] Anticorp@lemmy.world 7 points 3 days ago

because they dared live close to humans.

Poor dumb bastards.

[–] EarthShipTechIntern@lemm.ee 5 points 3 days ago

You sound like a conspiracy wonk.

They are the only true emperors & kings recognized by the flightless aristocracy.

Tis the human "royals" who are living lies!

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

Mosquito hawks do not, in fact, eat mosquitos.

I no longer respect those annoying fuckers.

Earthlings don't eat Earth either. They're still Earthlings.

Sperm whales don't eat sperm.

Mayflies don't eat May or any other month.

[–] pufferfisherpowder@lemmy.world 24 points 3 days ago (1 children)

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

[–] RedditRefugee69@lemmynsfw.com 3 points 2 days ago

No, you've been keeping the salinity high.

Thank you for your service.

Dobsonflies don't even eat Dobson!

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

[–] Anticorp@lemmy.world 6 points 3 days ago

Or ya know, that they're usually found hanging around near fruit.

It's not like they built the car, though.

The trick is to use other people's time and money to create crime against nature.

Are horseflies a lie because they don't eat horses?

[–] itslilith@lemmy.blahaj.zone 40 points 3 days ago (2 children)

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

[–] Seleni@lemmy.world 12 points 3 days ago (1 children)

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.

You already know what you call a fly with no wings

A walk

[–] Etterra@lemmy.world 15 points 3 days ago* (last edited 3 days ago) (1 children)

Reminds me of the old joke, what do you call a fly with no wings?

A walk.

[–] DrDystopia@lemy.lol 1 points 1 day ago

what do you call a fly with no wings?

The victim of a psycopath in the making.

[–] hperrin@lemmy.world 14 points 3 days ago* (last edited 3 days ago) (1 children)

They’re called fruit flies because they gather around rotting fruit.

But there are also “true fruit flies” which do eat fruit.

biological lab work with animal subjects is the closest things we have to Roman augury.

Drosophila are awesome! Been working on them for a long time:)

[–] PotatoesFall@discuss.tchncs.de 9 points 3 days ago (3 children)

Can somebody explain the fruit thing? I've seen fruit flies demolish fresh fruit. The amount of yeast biomass on them must be negligible at that point. Do the eggs/larvae spread the yeast before they start eating?

[–] psud@aussie.zone 9 points 3 days ago* (last edited 3 days ago) (1 children)

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

[–] AnarchoSnowPlow@midwest.social 6 points 3 days ago (1 children)

Doesn't even have to be actual booze. Apple cider vinegar + a drop of dawn dish soap works a treat.

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)

[–] RememberTheApollo_@lemmy.world 10 points 3 days ago

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.

[–] flora_explora@beehaw.org 4 points 2 days ago

Oh yeah, that brings up memories. We had to do the same experiments in genetics lab, too. I'll never forget the smell of fruit flies :/
