Habitat and ecology

Land-Use change

McComie^[2] hypothesized that the Moruga grasshoppers have changed their range due to the clearance of the primary forest for industrialization, human settlement, agriculture, and logging activities in Trinidad and Tobago.

Pest status

Major pest of banana, cocoa, breadfruit, cassava, citrus, mango, and teak in Trinidad ^[3]
