Like most katydids, males produce calling songs at night, though many species in this genus are so high-pitched or faint that they’re difficult for humans to detect without audio tools.
What Is Their Role in the Ecosystem?
They contribute to the balance of rainforest ecosystems by feeding on plant matter and serving as prey for birds, bats, and reptiles.
34. Acanthodis
Acanthodis is a genus of katydids typically found in Central and South America. These katydids are recognized by their spiny bodies and cryptic coloration, which help them blend into dry leaves and bark in tropical forests.
Identification
- Spiny body with leaf- or bark-like texture
- Color ranges from dull green to brown or grey
- Camouflaged wings with jagged edges
- Long antennae and strong legs
- Body size usually 30–45 mm
How Do They Use Camouflage?
Their wing texture and body coloration make them nearly indistinguishable from the forest floor or tree bark, helping them avoid detection by predators like birds and frogs.
Are They Active at Night?
Yes, they are nocturnal and become active after sunset. They remain motionless during the day, relying on camouflage for protection.
What Do They Eat?
Primarily herbivores, feeding on leaves and decaying plant material. Some may also scavenge soft-bodied insects if available.
35. Habra
Habra is a small genus of katydids native to tropical Asia, especially regions like Borneo and Malaysia. These katydids are known for their compact body, soft coloration, and tree-dwelling behavior.
Identification
- Small to medium-sized body
- Pale green or yellow-green wings
- Wings often rounded and leaf-like in shape
- Long, delicate antennae
- Size typically between 20–30 mm
Where Are They Found?
They are arboreal, often living in the mid- to upper canopy of tropical rainforests. They are most active during humid nights and are rarely seen during the day.
Do They Make Sounds?
Yes, males produce soft, irregular clicking or rustling sounds at night, used for mating communication. The sounds are usually too faint to be heard from a distance.
What Role Do They Play in Nature?
They help maintain plant health by grazing on soft foliage and also serve as food for nocturnal predators like bats, spiders, and tree frogs.
