Katydid nymph
Scientific Name: Tettigoniidae (nymph)
Order & Family: Order: Orthoptera, Family: Tettigoniidae
Size: Nymphs vary in size depending on their instar, but generally range from a few millimeters up to 2-3 cm (0.1-1.2 inches) for later instars. Adults can be much larger.
Natural Habitat
Typically found in vegetation such as grasses, shrubs, and trees in various environments including forests, meadows, gardens, and along roadsides. They often blend in with their green surroundings.
Diet & Feeding
Most katydids are herbivorous, feeding on leaves, flowers, and seeds. Some species are omnivorous, consuming small insects or insect eggs in addition to plant matter.
Behavior Patterns
Katydid nymphs are primarily nocturnal, feeding and moving about at night to avoid predators. During the day, they are often found motionless, relying on their camouflage to remain hidden. They undergo several molts (instars) before reaching adulthood. They are generally solitary.
Risks & Benefits
Katydids are generally harmless to humans, though some larger species could deliver a minor pinch if handled. They are beneficial to the ecosystem as they are part of the food chain, serving as food for birds and other insectivores. While some species can cause minor damage to garden plants by feeding on leaves, they are not typically considered major agricultural pests.
