A planthopper is any insect in the infraorder Fulgoromorpha, [1] in the suborder Auchenorrhyncha, [2] a group exceeding 12,500 described species worldwide. The name comes from their remarkable resemblance to leaves and other plants of their environment and that they often "hop" for quick transportation in a similar way to that of grasshoppers.
Planthoppers are the only animals known to possess a gear mechanism, [1] and Issus coleoptratus is the first type of planthopper to have the mechanism formally described. [ 2 ] [ 3 ] The mesh sector gears do not transform velocity or torque, and they do not convey much of the power; they only synchronize the jumping motion of the hind legs ...
Native to China, Vietnam, and Taiwan, spotted lanternflies (Lycorma delicatula) are invasive planthopper insects that feed on plant sap. The first confirmed sighting of spotted lanternflies in the ...
The brown planthopper (BPH), Nilaparvata lugens (Stål) (Hemiptera: Delphacidae) is a planthopper species that feeds on rice plants (Oryza sativa L.). These insects are among the most important pests of rice, which is the major staple crop for about half the world's population. [1]
Ricaniidae is a family of planthopper insects, containing over 400 species worldwide. The highest diversity is in tropical Africa and Asia and in Australia, with a few species occurring in the Palearctic and Neotropical realms. It is one of the smaller families in the planthopper superfamily Fulgoroidea. [1]
These gear-like structures have teeth that intermesh, keeping the legs synchronized when the insect jumps, preventing it from spiraling. This is the first planthopper species in which the function of these gear-like structures was carefully described, [6] though their existence had been known for decades. [7]
Information on the biology of the Derbidae is scarce. They clearly belong to the planthoppers which by nature feed by sucking the sap of plants and they have the corresponding mouthparts. However, relatively little is known about their life cycle, their feeding habits and their host plants.
Scolypopa australis, commonly known as the passionvine hopper, is a species of insect in the Ricaniidae family of planthoppers (Fulgoroidea) that is native to Australia and was introduced to New Zealand. [1] [2] Despite its name, they are found not only on passion vines, but on many plant species, including kiwifruit and the lantana.
