The species I put here are flies and similar flies, meaning the two species are similar, but not the same and play a different role too.
Two of these species, the first of which plays damage to plants (pests), and one serves as carriers of disease, this one species are often called flies, and they carry dirt everywhere, including food, which can lead to disease very dangerous for humans
How do we see the differences between the two species !
In terms of shape, the two species are ssma, but there are slight differences, the first species (pests), they have brown eyes, and have higher legs, in addition, this first species (pest) has a very fast movement capability.
The second species (fly), this species we often meet, because this species (flies) everywhere, and this species (fly) that bring disease outbreaks, through the food we consume.
