grasshopper Dissection |
Structure/Function:
The grasshopper has bilateral symmetry, and is very complex. Air enters through spiracles, to the trachea, and into the tracheoles. They have an open circulatory system and an exoskeleton for protection. It has extensive cephalization with a ventral nerve cord and ganglia. A complete digestive system is present, and reproduction is sexual. They also have wings, jointed legs, three body regions, and antenna.
Ecology:
Grasshoppers lay their eggs in late summer and over winter they incubate in the soil. The grasshoppers prefer warm weather because it helps with their survival. Sometimes a bacterial disease is contracted when the weather is warm and humid this cause the grasshopper to climb to a high point and die. Grasshoppers eat only leaves, they are strict herbivores.
