Katydid (specifically a Bush Cricket or True Katydid)

Deciduous forests, woodlands, gardens, and shrubbery across North America and other temperate regions.

Primarily herbivorous, feeding on leaves, stems, and flowers of trees and shrubs; occasionally scavenges on other insects.

Mainly nocturnal; they are known for their leaf-like camouflage and the loud 'katy-did, katy-didn't' sound produced by males rubbing their wings together to attract mates.

Generally harmless to humans; they benefit the ecosystem as a food source for birds and bats, though some species may cause minor foliar damage to garden plants.
