Filly - insect from the order Orthoptera superfamily Locust. Their closest relatives are grasshoppers and crickets.
The appearance of the fillies
To date, more than 3, 800 species of these insects are known. Only in Russia there are more than six hundred species.
A filly is an insect very similar to a grasshopper. She has the same arrangement of hind legs: with the knee raised high above the body. On the back of the grasshoppers and grasshoppers are folded hard elytra. And on the head of both species of insects are antennae antennas. Even the filly chase almost like grasshoppers, only much louder!
In fact, it is difficult at first sight for an uninformed person to determine who is in front of him. The grasshopper and the filly (insect) are very similar. Photos of both only confirms this.
Nevertheless, there are differences. Just need to carefully look. Basically they are due to the fact that insects lead a completely different lifestyle.
Feeding the fillies
Among a warm warm day, you can often scare a flock of insects that look like grasshoppers out of the grass. But it is safe to say that this is the locust. After all, grasshoppers are predominantly nocturnal, and during the daytime they hide somewhere. Only at nightfall do these predators go hunting.
A filly (insect) eats vegetation. Therefore, she does not need to wait for the night. And it is worth noting that this herbivore insect easily adapts to eating any plants: their leaves, seeds, fruits, and in some cases, the stems.
Damage caused by farm fillings
Many believe that the fillies are quite harmless. After all, they, although they belong to the locust, are single insects. However, in 1939, KN Filatov, a senior researcher at the Chelyabinsk stronghold of the All-Union Institute of Plant Protection, prepared a report on the dynamics of non-locust locusts, that is, grasshoppers.
His research has proven how dangerous the filly can be to agriculture. According to the documentary data, in the years 1883-1892, these voracious insects regularly destroyed crops on huge areas in the Kurgan district. It was a real disaster for the peasants. And only in 1892, the people in all the crowd went on a manual hunt. With the help of special canopies, they managed to catch 155, 951 pood of fillies!
Local historians say that in 1894, when the last insect was buried in the ground, the owner of the powder factory Balakshin erected a monument in honor of this event at his own expense. Unfortunately, to this day it has not been preserved.
Fight against the filly
Having noticed this harmful insect in one's garden or garden, one should try to reduce the number of fillies with frequent sprinkling. The increased air humidity has a negative effect on their reproduction.
Processing plants 3% solution of Bordeaux liquid helps get rid of the fillies. Eating plants that have been sprayed with poison, insects die in 1-3 days.
So that next year the invasion of the fillies will not resume, it is necessary to mow all the plants from the shoulders in the fall, deeply plow the ground and burn in. This will destroy the eggs of the filly in the ground.
There is one more way - to breed hedgehogs on the site. This is for whom the fillies and other pests of gardens and gardens are a joy! At the same time, these thorny predators will destroy together with the fillers of slugs and mice, if they think of settling on the site.
External differences between grasshoppers
From the foregoing, it is clear why these insects cannot be confused. After all, grasshoppers eat the larvae and harmful insects, benefiting man. And the filly, by contrast, is itself a pest, destroying the crop. Because it is so important to know how they can be distinguished by appearance.
In comparison with a grasshopper, a filly is an insect with a slow-moving head. Her muzzle is blunt, with powerful jaws.
It is known that grasshoppers are attributed to the suborder Long-haired, and grasshoppers to short-haired. This is understandable. After all, the filly does not have to search for a victim with their help. She does not need to hunt to feed, tracking down his victim.
A filly is an insect that has an oblong belly that is longer than that of a grasshopper. This is due to the fact that the amount of food she has to digest is quite large.
The forelegs serve the filly only as a support, while the grasshopper with their help catches and holds the victim. Therefore, in the herbivore insect, these limbs are weaker and shorter. Less developed in fillets and hind legs. Therefore, her jumps are not as far as those of a grasshopper.
The females of these insects have more pronounced differences. The female grasshopper has a rather large, sword-shaped oviposition behind. In a filly, it is short and almost invisible to the human eye. She lays eggs directly into the soil.
Hearing organs in fillies
Not everyone knows that many insects do not hear with their ears at all, as is customary in mammals, birds and reptiles. For example, grasshoppers use their legs for this purpose. Organs of hearing they are located on the legs of the front legs.
The fillers hid their ears at all. Their auditory organs are located on the sides of the belly, in the region of the first segment.
The organs of sound reproduction in fillies
On a hot afternoon, there is a loud chatter in the fields and meadows. Usually, people smile when they hear these sounds, and they say: “That’s how the grasshoppers have been indignant!” But this is a wrong judgment!
Grasshoppers, by nature, sit quietly during the day. Therefore, it is impossible to hear them. Staring in broad daylight, either locusts or filly. Moreover, only males do this. In this "musical" way they attract females. There is a second explanation for the loud chanting of male fillies. With their sounds, they warn other males that this territory is already occupied.
Produce their sounds filly, rubbing tubercles located on the thighs of the hind legs, about the vein under the elytra.
An interesting fact is that the color of the locust depends not on the appearance of the species, but on the environment. If around the growing insect a lot of bright green, you get a green filly. An insect that lives in the steppe, where there is less greenery, but a lot of brown soil, along which you have to move, will become gray-brown.
Although the lower wings in some species have a bright color. For example, in the blue-winged and red-winged filly, in addition to the protective coloration of the elytra, there is also a method of protection against enemies.
Anticipating impending danger, they abruptly soar upward with the noise, revealing their bright wings. And in a moment they go down again. From the side it looks like bright flashes of fireworks.
