Summary
Phaneropterinae, also known as Phaneropterine katydids or false katydids, are a diverse subfamily of bush crickets distinguished by their unique physical and reproductive traits, primarily found in arboreal habitats where they camouflage themselves among vegetation.
Physical Characteristics
Phaneropterinae are characterized by tympana on the foretibia that are exposed, and forewings that are shorter than hindwings. They generally exhibit a green or brown coloration for camouflage, although some species can be Batesian mimics resembling wasps.
Identification Tips
Look for the distinct exposure of tympana on the foretibia and the proportionately shorter forewings compared to hindwings. Many species are well-camouflaged against their arboreal background.
Habitat
Primarily arboreal, Phaneropterinae inhabit shrubs and trees where they feed on leaves and twigs.
Distribution
Found worldwide, particularly in tropical and subtropical regions with a significant diversity across the Americas and Africa.
Diet
They primarily feed on leaves and twigs, making them herbivorous insects.
Life Cycle
Phaneropterinae typically undergo incomplete metamorphosis, with eggs hatching into nymphs that resemble smaller versions of adults. Nymphs grow through several molts before reaching maturity.
Reproduction
Reproduction involves the female laying eggs either glued in double rows to twigs or inserted into the edges of leaves, rather than depositing them in the ground.
Predators
Specific predators are not detailed, but like many insects, they may fall prey to birds and other insectivorous animals.
Ecosystem Role
As herbivores, Phaneropterinae play a role in leaf consumption and can influence plant health in their habitats. They also serve as prey for larger animals.
Economic Impact
While some species can be present in large numbers that may cause superficial damage to crops, significant economic impact is rare as they usually remain solitary and unnoticed.
Collecting Methods
- Sweep netting in suitable habitat
- Hand collecting on vegetation
Preservation Methods
- Pinning
- Breeding in captivity for study
Evolution
The name Phaneropterinae is derived from the genus Phaneroptera, meaning 'visible wing', indicating an evolutionary adaptation for camouflage.

Misconceptions
They are often confused with true katydids due to their similar appearance; however, the term 'false katydid' refers to their distinct phylogenetic classification.
