someone who is an EXPERT at bugs can answer this! THATS NOT ME.
mandibles!
It has four leg like things near its mouth that is used to store food while it is eating, it is called the labium and the maxilla.
Grasshoppers have chewing mouth parts, meant for eating solid plant material. Butterflies have sucking mouth parts meant for sipping nectar.
As living things grow in their life, their bodies grow and adapt to many things. A grasshoppers mouthparts are adapted to chewing fibrous plants.
They are not "teeth", but rather mandibles. They help the grasshopper to tear off parts of a plant, then help it chew its food. They are on the sides of its mouth, most are black in color, and most are inside of the grasshoppers mouth, though I have seen a few with mandibles outside of the mouth.
Grasshoppers
Fabrosaurus is likely the same as Lesothosaurus. They were small, herbivorous plant eaters adapted to eating tough plant material that grew close to the ground.
for aphids, buy a bag of ladybugs at Home Depot, and for larger bugs, have a sprinkler near the plant. (grasshoppers are affraid of water)
From the environment in which they live. They are plant eaters.
Depending on the species, sea turtles may be carnivorous (meat eating), herbivorous (plant eating), or omnivorous (eating both meat and plants). The jaw structure of many species is adapted for their diet. Green sea turtles have finely serrated jaws adapted for a vegetarian diet of sea grasses and algae.
Capuchins are omnivores. They eat a variety of food including - plant material, insects, birds and their eggs.
Ladybugs are one insect that eats plant-eating bugs. Thought of as a gift from god.
Because that's what they adapted to do. Plant eating animals usually have to spend an enormous amount of time eating to get the amount of energy a meat eating animal gets with one kill.
