(Being the voracious plant eaters that they are, grasshoppers can
be quite destructive to agricultural crops and are generally disliked
by the farmers. However, they do have a positive side as well.
The grasshopper droppings or frass that fall on the soil return the
nutrients back to the soil, thereby contributing to the nutrient turnover.
This frass is also consumed by birds and various arthropods and so
are a source of food to them. Thus, grasshoppers have their pros
and cons, but above all being herbivorous, they form a perfect link
between plants and the rest of the ecosystem)-
