Summary: The biting cattle fly in the countryside, and these roles!
In the past, when farming in the countryside, almost every household had to raise one or two cattle. Cows are very attracted to insects and flies, including cattle flies. The bullfly is larger and faster, resembling a small fighter jet. When you see a cow fly sucking the blood of a cow, you must shoot it to death in time, sometimes the bullfly will attack humans, and it will be very painful when it bites, and it will swell up a large bag, which is really a lot of insects that are very annoying.
Cow fly is the common name of the fly, also known as cattle mosquitoes, cattle flies, blind ants, in the northeast forest area is also known as "blind touch" or "blind fly". Isn't it a little dizzy to see such a large list of aliases of the bullfly? Do cattle flies belong to flies or ants? In fact, the oxfly belongs to the diptera family. Just by listening to these aliases of the cattle fly, you can see that the cow fly looks like a fly. But he is slightly larger, like a mosquito, and likes to tease, and his voice when flying is very similar to that of a horse wasp.
The bullfly is grey-black, stout, long-ovate in shape, and about 19 mm long. It is about 6 mm wide. The head is broad, hemispherical, with large compound eyes on both sides, and the mouthparts are sucking, which is particularly suitable for sucking blood. The body is mostly covered with black soft hairs and white powder substance, and the antennae are yellow. Cattle fly is distributed throughout China, adult insects usually like to live near the water and high temperature, paddy fields, swamps, near still water is their best reproductive environment.
Female cattle flies have a strong clawing ability, and thick-skinned animals such as cows and horses are very susceptible to their invasion, and of course humans are also disturbed by them. Adult cattle flies are active during the day, and at noon is the peak period of cattle fly activity, so every year from May to August, a large number of cattle flies mature, and at this time, when you go to the countryside, you can see the cattle flies around the cows and horses.

For such pests, humans also try their best to control the number of cattle flies, some people have sprayed efficient repellent on the body of cattle and horses, although the effect is good, but only short-term effect, want to use for a long time will waste a lot of manpower and material resources.
Fortunately, after human research, it has been found that some insects in nature are natural enemies of cattle flies, such as ladybirds and cryptoptera larvae that feed exclusively on the eggs of cattle flies. People can use these predators to eliminate flies.
