Eastern lubber grasshoppers are huge grasshoppers that come from the southern part of the United States.
Apparently they can cause some damage to crops but they are not really the worst pests.
Eastern lubber grasshoppers are famous for their size, their coloration, in particular that the nymphs do not really look like the adults.
The pictures were take at different times in the Toronto Zoo where eastern lubber grasshoppers are exhibited in the Americas pavilion. See how the adults differ from the young.
