Is it okay to eat this kind of "fly"? !

Recently, many fruits and vegetables have come on the market.

It really fully satisfied everyone's appetite.

but,

Please make sure to throw away the fruit peels in the trash can in time.

Otherwise... hehe,

You will see many small flying insects coming from nowhere.

When you have just washed or cut the fruit,

Just surround it.

They are naturally the fruit flies that love fruits the most!

Fruit flies are much smaller than houseflies.

There is also a pair of large compound eyes on the head.

The so-called compound eyes are composed of many small eyes.

So here comes the question,

The fruit fly's large, dense eyes,

Does the world seem clearer?

This really needs to be discussed from several aspects.

actually,

The resolution of the world in the fruit fly's compound eyes is really average.

Not as good as us, but more like a mosaic.

Each ommatidium forms a pattern image

Or let's put it more simply, pixels.

Put together to form a complete picture.

That's strange.

These evolved big eyes can’t be just for decoration, right?

Well, this is about resolution.

It's not just about spatial resolution.

There is also time resolution,

That is the resolution when looking at moving objects!

We know that due to the persistence of vision,

Movies must be at least 16 frames per second.

That's 16 images per second.

Only then will people think that the picture is coherent.

For the sake of effect, movies are now shot at 24 frames.

As for the compound eyes of fruit flies,

This number is 300, which means,

To achieve 300 images per second,

The fruit fly thinks this is coherent.

So, fruit flies,

Flies are so hard to hit!

You swung the fly swatter quickly,

What they see is like a slow-motion replay.

They can quickly identify the direction of danger.

Immediately choose a suitable direction to escape.

At the same time, the compound eyes are very large.

It almost occupies the entire head, providing a very wide field of vision.

How big is the field of vision of our human eyes?

At most, it's about 180 degrees.

Fruit flies can see almost 360 degrees.

So,

The ultimate goal of evolution is survival.

You have to survive first.

On the fruit fly,

In addition to compound eyes and mouthparts for eating food,

The mouth.

There are also two pairs of hairy tentacles extending outward.

This pair of antennae is the fruit fly's nose.

This kind of fluff is actually a kind of wrinkles.

This type of structure gives the "nose" a larger surface area.

This makes them more sensitive to odor molecules.

Can easily smell odors that we cannot smell,

This is why fruit flies can survive in a short period of time.

Just fly around our fruit!

Fortunately, fruit flies are quite clean.

Unlike flies, they are not picky eaters and feed on carrion.

In particular, they mainly use animal excrement as their staple food.

Fruit flies basically only attack fruits and vegetables.

And their immune system

The lord is not as strong as a fly,

If it is contaminated with bacteria, it will die.

And, pounding at the root,

Fruit flies and flies are not from the same family.

They belong to the same order Diptera, but are classified in different suborders.

You must have also heard that

Soak bayberry in salt water for a while before eating it.

Because there is a high probability that there are small white worms in the flesh.

And this little bug is the larva of the fruit fly.

Bayberry has no outer peel to protect it.

It is easy to be invaded and difficult to spray pesticides.

When ripe, it is sweet and soft.

The fruit fly lays its eggs in it.

Other fruits that are easily damaged,

There is also a fig with a hole in its surface.

It leads directly to the interior, and its defense is also very weak.

But don't worry, these larvae are very clean.

Human gastric juice is more than enough to deal with them.

When you eat it, it is simply digested as protein.

Now is a good season to eat bayberry.

I wish you have delicious bayberries and you can never get enough of them!

But remember to take out the trash in time!
