Final answer:

The Rocky Mountain locusts of the 1800s differed from today's grasshoppers in their widespread presence, high destructive potential, and species. The Rocky Mountain locust, now an extinct species, was known for its enormous, crop-destroying swarms. In contrast, modern North American grasshoppers do not aggregate in such devastating groups.

Explanation:

The Rocky Mountain locusts of the 1800s were different from the grasshoppers today in various ways. One of the stark differences lies in the extent of their spread and their impact on human life. Rocky Mountain locusts were not just widespread, they were known for the mass destruction they caused to crops. Historical reports depict swarms of these insects devouring everything green in their path, covering the ground six to twelve inches deep, thereby causing significant harm to agriculture. Today's grasshoppers, on the other hand, while still being a pest, do not gather in such vast, destructive swarms.

Furthermore, the species that the Rocky Mountain locust belonged to, Melanoplus spretus, is now considered extinct, while various species of grasshoppers continue to thrive in North America. Hence, today's grasshoppers differ not just in behaviour but also in terms of species from the Rocky Mountain locust.
