The Broad-winged Katydid (Microcentrum rhombifolium) is a common North American katydid known for its bright green leaf-like wings and loud nighttime calls. These insects are closely related to grasshoppers and crickets and are often heard singing in trees during late summer evenings.
Quick Facts
- Order: Orthoptera
- Habitat: Forests, gardens, and shrubs
- Diet: Leaves and plant material

Identification
Broad-winged katydids have bright green bodies and large leaf-shaped wings that provide excellent camouflage among foliage. Adults measure roughly 1.5 to 2 inches long.
Their long antennae can extend several times the length of their bodies, a characteristic common among katydids.
Distribution
This species is widely distributed throughout the eastern and central United States and southern Canada.
Life Cycle
The life cycle includes egg, nymph, and adult stages. Nymphs resemble miniature adults and gradually develop wings after several molts.
Pest Status
Broad-winged katydids occasionally feed on leaves but rarely cause serious plant damage.
Prevention
- Maintain healthy plant ecosystems
- Encourage natural predators such as birds
- Avoid excessive pesticide use
Control
Control is rarely necessary since katydids play a minor role in plant damage and are part of healthy ecosystems.
