Judging from the ability of flies to recognize colors, what color should fly swatters buy?

There are still a lot of colors that can be distinguished by the eyesight of flies, flies generally like hot spots, generally like to bask in the sun, and on the other hand, they also like warm colors and do not like blue.

Flies are really annoying, not only the sound, but also the annoyance that flies are not afraid of dying, flies often fly everywhere and crawl everywhere, with a lot of germs on their bodies, and climbing on people will make people feel very disgusting.

The reason why it is said that the eye is the structure of the fly's eyeball, like the dragonfly, is almost no dead end, and the fly swatter has fallen very quickly, but many times the fly can still dodge.

Individuals are still more experienced in fighting flies, and the color of the fly swatter is not much related, basically all of them depend on hand speed, and the general insects feel that when something is slowly approaching, there will be no alertness, so when the fly needs to be slowly approached, when the distance is enough, quickly shoot, a fatal This is the most effective.

Generally, most flies are more short-sighted when they have the advantage of full perspective, and there is a very classic sentence: like a fly lying on the glass, the future is bright, but there is no way out. If you are buying a fly swatter, it is recommended to buy a color you like, because the flies are all based on the hand speed, and the color has nothing to do with it, the best thing is to buy a darker color, so that the flies will not look dirty.

It is best to buy a sticky fly board, which is a principle with a sticky mouse board, but put some bait first, which is more efficient than fighting flies and will be more hygienic.

<> flies prefer warm, phototropic colors. Mosquitoes in most parts of our country generally prefer black, and all dark colors (such as: brown, dark green, dark gray, dark blue.

Dark red, etc.) are the environments in which mosquitoes like to live, so mosquitoes begin to become active as soon as it gets dark. Personally, I think you should buy a dark black fly swatter or a blue one, which are the favorite colors of flies.

There are three types of flies: black, gray, green, and the most common is black and gray;

Flies are insects that are frequently active during the day and have obvious phototaxis. At night, it is stationary. Activity, habitat, depending on the species, season, temperature and region.

The activity of flies is greatly affected by temperature. It can only crawl at 4 7 o'clock, fly at 10 15 o'clock, feed, mate, and lay eggs at 20 o'clock or more, it is especially active at 30 35 o'clock, 35 40 stops its activity due to overheating, and dies at 45 47 o'clock.

The way flies overwinter is quite complex. It can overwinter in a pupal state, as well as in the form of maggots and adults. In the cold and temperate regions of the north, there are no active houseflies in nature, but there are still adult flies in the indoor heating room.

Generally three kinds:

Black, gray, green, and most commonly black and gray.

Flies, four forms in a lifetime:

Blue and black are more attractive to flies.

Flies and mosquitoes can also see the color. Houseflies hate blue the most, so they are reluctant to approach blue doors, windows, and curtains. Mosquitoes can distinguish yellow, blue, and black, and have a preference for black.

Answer, flies come in three colors: black, green and gray.

The flies are black, gray, green, and some are quite large, like cows.

I've seen black, gray, green, red, white, black and gray.

I've seen black, brownish-green.

Houseflies hate blue the most.

The normal human eye can perceive the colors of the world, recognizing red, orange, yellow, green, cyan, blue, and purple, plus various transition colors between them, there are about 60 kinds in total. So, what about the ability of animals to sense color? Scientists have studied this.

Studies have confirmed that most mammals are color blind. Cows, sheep, horses, dogs, cats, etc., can hardly distinguish colors, reflected in the color of their eyes, only black, white, gray 3 colors, dogs can not distinguish colors, it looks at the scenery like looking at a black and white**. In addition to their legs, dogs mainly rely on their sense of smell and hearing to hunt their prey.

Our human "close relative" apes live a prosaic gray life. Voles, house mice, yellow squirrels, chipmunks, squirrels, prairie dogs, etc., also cannot distinguish colors. Giraffes can distinguish yellow, green, and orange.

Deer have the strongest recognition of gray. Interestingly, although the zebra is colorblind, it is able to use color to protect itself. Zebras and other animals graze together, and the black and white stripes can attract attention, so when danger arises, all zebras will quickly flee as soon as the lead horse moves.

When the zebra runs, the shaking of the black and white stripes makes it difficult for the predator to quickly determine the distance, and the zebra can escape safely.

This is not the case with birds. With the exception of some birds that are accustomed to nightlife, such as owls, which cannot recognize colors because there are no cone cells in the retina, many birds have a sense of color. Crows fly at high altitudes and need to find a place to land, and the color will help them judge the distance and shape, so they can catch the insects flying in the air and land lightly on the branches.

The birds' ability to discriminate colors is also beneficial in their search for mates. Think about it, male birds often use bright feathers to attract the opposite sex, if they can't feel the color, then what is the charm of male birds?

Most aquatic animals have the ability to distinguish colors. The sea bass can sense color, and the biologists feed them with red larvae, and when they get used to it, they switch to red wool to feed them, and the sea bass actually eats it.

Although insects are lower animals, they are more intelligent than mammals in their ability to distinguish colors. Dragonflies have the best visual appearance against color, followed by butterflies and moths. Flies and mosquitoes can also see the color.

Houseflies hate blue the most, so they are reluctant to approach blue doors, windows, and curtains. Mosquitoes can distinguish yellow, blue, and black, and have a preference for black. Industrious little bees live among thousands of purple and red flowers, but they are red blind, and bees can distinguish three colors: green, yellow, and blue.

However, bees can see ultraviolet rays that are invisible to humans, and can accurately distinguish ultraviolet rays from various shades of white and gray.

First, the color difference:

Green-headed fly: resembles a mung bean, and is customarily called a mung bean fly.

Red-headed flies: red on the head and bright green on the back.

2. Evolutionary differences:

Green-headed fly: The green bean fly is a species of fly that is widely distributed in most parts of the world, and its scientific name is "mercerized green fly".

Red-headed flies: Red-headed flies are domesticated from the mercerized green fly among wild flies and are commonly found in farm toilets.

3. Differences in living habits:

Mallard-headed flies: Mung bean flies feed on rotting organic matter, and adults are the most sensitive to fishy and foul-smelling fish meat, so they are commonly found in unhygienic environments. The mung bean fly has licking and sucking mouthparts, which can contaminate food and spread diseases such as dysentery.

Red-headed flies: The larvae feed mainly on human and animal feces, which are more common in the manure pits of rural toilets in summer.

There are two kinds of flies with blue luster, such as the fly and the glazed parasitic fly.

1. FlyFlyflies are widely distributed and are found almost everywhere on Earth where people live. Adults are medium to large, and their body color varies greatly, most of them are green, green, blue, brown and other metallic luster, and a few species have a black background and are covered with light color powder.

2. Glazed parasitic fliesThe body length of the glazed parasitic fly is 20 22 mm. This species is a large species with a particularly bright appearance among the members of the parasitic fly family. The appearance resembles that of a fly, but the back of the body is covered with long spines; The body color is a bright blue with a metallic luster; Wings black.

I like rotten meat, fish or excrement, and there should be no special color in it, mainly the smell.
