Katydid

Natural Habitat

Found in a variety of habitats including forests, grasslands, meadows, and gardens, often camouflaged among foliage. The one in the image appears to be on tree bark, which is less common but still within their range.

Diet & Feeding

Most katydids are herbivorous, feeding on leaves, flowers, and seeds. Some species are omnivorous, also consuming small insects.

Behavior Patterns

Katydids are primarily nocturnal, using their camouflage during the day to avoid predators. Males produce characteristic 'singing' sounds (stridulation) by rubbing their wings together to attract mates. Their long antennae are used for sensing their environment. They are known for their excellent camouflage, often mimicking leaves or twigs.

Risks & Benefits

Generally harmless to humans. They can sometimes be considered minor agricultural pests if present in large numbers, feeding on cultivated plants. Ecologically, they are an important part of the food web, serving as prey for birds, spiders, and other predators, and contributing to plant decomposition by consuming plant matter.
