Cardiodactylus guttulus
Orthoptera / Family: Eneopteridae
- Total length
- approx. 37 mm
- Range
- The Ryukyu Islands (south of Amami-Oshima) and Taiwan
It lives on grasses and trees, feeding on their leaves. In the diorama, it appears to be clinging to a tree root.
Although its Japanese name suggests it belongs to Gryllidae, it actually belongs to Eneopteridae. It exhibits overall brown coloring, with the bases of the legs being yellowish brown and the wings having remarkable yellow spots. The antennae are strikingly long. Females have a tube-like structure used for laying eggs, clearly distinguishing them from males.
Being abundant, it can be easily found in various places from farmlands to mountain forests. Both day and night, it makes a sound like "sh-shi." Adult insects emerge from August to January.
Habitat of This Animal:
A:Forest along the valley - A1:Accessible forest
While there are also high mountains in Tokunoshima Island, there are also plateaus formed by raised coral reefs surrounding such mountains. These plateaus, with base rock made of Ryukyu limestone, formed a complicated terrain as a result of erosion. Forests growing on such plateau are made of plants preferring limestone soil, and this is one of the important factors characterizing the nature of Tokunoshima Island.
