In this case, the two species have coevolved by modifying behavioral traits (moths) and physiological traits (bats).
<h3>What is coevolution?</h3>
Coevolution is a particular type of evolution where a selective pressure imposed by one species serves to generate an adaptive change in another species and vice-versa.
Coevolution is fundamental in predator-prey relationships and leads to the emergence of new traits that are selected by natural selection.
In conclusion, the two species above have coevolved by modifying behavioral traits (moths) and physiological traits (bats).

So we can conclude that farmer's action have a negative impact on the ecosystem due to presence of no predator or controlling agent of that bird.
