Zoraidini

Like in other derbids, the adults suck the sap of plants while the nymphs live mainly in decaying organic matter.

[9][10][11] In Asia, Australia and the Pacific, the distribution of species from the tribe Zoraidini ranges from India and Sri Lanka in the West to the western Pacific (Indonesia, Guam, the Philippines) as far south as Papua New Guinea, the Solomon Islands and northern Australia.

In eastern Asia, they have been also reported from subtropical regions as far north as parts of Japan and south-eastern Russia.

[13][2][14] The tribe Zoraidini is characterized by a combination of several features which include:[1][4][9][13] The long and narrow forewings, combined with the very short and also narrow hind wings, are the most important features of the tribe Zoraidini.

[19] In cases where the hindwings are extremely small, they are unlikely to have a role in the flight of the insects and probably only serve as a communication (stridulation) organ.

[9] The main feature of the head is the narrow, compressed face (frons), typically with the ridges on the side (facial carinae) nearly or completely meeting throughout most of its length.

The facial carinae very rarely extend much further in front of the eyes, unlike in some other groups of Derbidae and the profile of the head is typically flat and usually evenly rounded.

The antennae are often long like in the type genus Zoraida and they are not branched like in other groups of Derbidae.

On average the forewings are between 7 and 12 mm long, in contrast to the compact body which is usually not more than half that length, from the head to the end of the abdomen.

[3] Several species seem to be common on coconut or other palms and in Asia Proutista moesta is regarded as harmful to sugarcane in several countries.
