Overlooked Details - Locusts and Leaf Hoppers

When writing an alien world it is important to remember the details. For instance, does the ecosystem have the equivalent of locusts? While it is tempting to only focus on the "interesting" bits like who is in love with who and what the nobel in exile is doing depth of writing requires bits like the old peasant stepping out of its hut, squinting at the unnatural cloud gathering on the horizon, and proceeding to curse into the wind.  Alternatively there can be the equivalent of leaf hoppers. The young maid is striding through a field and pauses to twist her face into a grimace before violently shaking her feathers. Dozens of little blue-green specks fly out and she continues on her way.
