A large number of unknown black insects are now in the homes of residents of Beijing, Tianjin and Hebei
Without hesitation, summer is the season I hate the most. The main reason is because of the discomfort of the body sensation caused by the high temperature, which can also be solved by air conditioning indoors, and can only sweat outdoors, and this year's temperature is recognized as an abnormally high temperature. But for many people who also hate summer, the most annoying thing about summer is that a large number of mosquitoes will come out to party, and every few days there is news of snakes or insects flooding, and these two days also appear.
Since August, netizens living in Beijing, Tianjin and Hebei have continuously found some black insects in their homes, they are obviously some kind of beetles, the whole body is black, with 3 pairs of feet, and some tentacles and wings are all there. Because it looks like a cockroach from a distance, many people feel worried. Will these large numbers of insects cause harm to humans?
In fact, this insect is too common, they are called The Chinese Tsubasa, August is their breeding period, so every year at this time, there will be many people worried about them, at that time will definitely be answered, but after a year everyone will forget the light.
Today, we're going to talk about this insect.
Chinese Tsubasa
The Chinese leptopod is an insect of the coleoptera, family Lycaenidae, and the members of this subject are more than 30,000 species worldwide, and the Chinese leptobulum is only described in 1845 as a common small ground beetle, because it is distributed in most parts of the continent, so I believe most people have seen them, but because they are so inconspicuous, it is easy to forget or confuse.
Their body length is only 11.5-15.5mm, and the width is about 6.0mm. Most of the foot armor is known for its long legs, but the feet of the Chinese foot armor are not very long, but it still retains the characteristics of the step nail family, that is, their black glowing carapace and reddish-brown wing sheath; The jaws, tentacles, antennae, lateral margins and posterior parts of the dorsal plate of the anterior thorax are also brownish red, and its breastplate is nearly rectangular, the dorsal carapace is oval, and the wing sheath has 9 longitudinal grooves; They have 4-5 spines on their feet, and the ventral surface of the feet has sticky hairs, allowing them to walk on some smooth planes.
Although the description is very lively, from a distance, they are too small beetles that can be seen everywhere, and they are occasionally recognized as cockroaches.
Is it a pest or a beneficial insect?
Most of the step beetles are not pests, because they prefer meat, all kinds of insects are on their menus, such as spiders and arthropods are also their favorite, so basically they are also beneficial insects, because many pests will be swallowed by them, such as aphids, ladybugs, etc., the Chinese step beetles are naturally the same. However, despite its preference for meat, the Chinese Tama is difficult to cut grass, so in the case of large reproduction, it is also a pest for the area where pasture is planted.
Paradoxically, let's just think of them as 80% beneficial and 20% pests.
But if they enter our homes, they are completely beneficial insects, because they do not attack humans, and they will feed on various insects in the room when they enter human homes; And they don't spread any parasites and bacteria, so there are no disadvantages except that they don't look good.
How to deal with them?
But not looking good is the original sin. If you want to drive them away, there is actually no special practice, it is nothing more than to wrap them up in paper and throw them out, and sweep them out with a broom.
Because they are also phototropic, the way to avoid them is first to turn off some non-essential lights, and then to close the doors and windows.
