time flies like an arrow, fruit flies like a banana

[–] [email protected] 4 points 1 day ago

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

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.

[–] [email protected] 12 points 2 days ago

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

[–] [email protected] 16 points 2 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.

[–] [email protected] 7 points 2 days ago

because they dared live close to humans.

Poor dumb bastards.

[–] [email protected] 5 points 1 day 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!

Calm down, Zeno.

Mosquito hawks do not, in fact, eat mosquitos.

I no longer respect those annoying fuckers.

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

Was he gender, species, and time fluid?

[–] [email protected] 4 points 2 days ago

All the fluids. Except water on Mars, he didn't like that one bit.

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

A walk.

[–] [email protected] 1 points 6 hours ago

The victim of a psycopath in the making.

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

[–] [email protected] 40 points 2 days ago (2 children)

Without a lie they'd just be horsefs

Ok let me introduce you to the barn owl

[–] [email protected] 3 points 1 day ago

Do they eat barns?

Polar bears are responsible for the ice caps disappearing.

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.

[–] [email protected] 1 points 1 day ago
[–] [email protected] 23 points 2 days ago

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

[–] [email protected] 3 points 1 day ago (1 children)

You're right. They only drink horse (and cattle) blood.

Horse or cow vampire fly is a little long winded for a name.

[–] [email protected] 1 points 1 day ago

But it does sound kind of cool!

[–] [email protected] 14 points 1 day ago* (last edited 1 day 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.

You already know what you call a fly with no wings

A walk

I wish I had the time and money to create crimes against nature.

[–] [email protected] 2 points 1 day ago

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

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

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

I always felt bad for em, we either drowned them in alcohol or froze them. I also felt guilt boiling the ecoli I spent time genetically engineering (in a genetics uni lab)

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?

[–] [email protected] 9 points 1 day ago* (last edited 1 day 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

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

[–] [email protected] 3 points 1 day ago

I guess not everyone has easy access to booze

[–] [email protected] 11 points 2 days ago* (last edited 2 days ago)

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)

[–] [email protected] 10 points 2 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.

Where my cheeky FlyNap sniffers at?
