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.
The gears keep the hind legs in synchronization, allowing the bugs to jump accurately in a straight line, at an acceleration of nearly 400 g in two milliseconds. [2] Each leg has a 400-micrometer strip of tapered teeth, pitch radius 200 micrometers, with 10 to 12 fully interlocking spur-type gear teeth, including filleted curves at the base of ...
These minute insects, colloquially known as hoppers, are plant feeders that suck plant sap from grass, shrubs, or trees. Their hind legs are modified for jumping, and are covered with hairs that facilitate the spreading of a secretion over their bodies that acts as a water repellent and carrier of pheromones . [ 1 ]

The nymphs have no wings, but can move about, and are defensively covered in wispy white wax, with a plume of waxy tendrils. Like other bugs in this family, both adults and nymphs feed by piercing the bark with their mouthparts and sucking sap from the phloem. The adults are mobile and can jump if disturbed. [3]
These enlarged femora allow for the springing action of these insects when disturbed. The jumping mechanism of flea beetles has been studied extensively. [4] One study looked at several species of flea beetles, including the Altica cirsicola species, and described the jumping mechanism of these beetles to be very efficient. [4]
The colors and the design of these bugs represent a warning to predators. They also emit a noxious odour when disturbed. Main host plants are Gossypium species , Coffea arabica , Citrus species and Vernonia amygdalina . [4] This species reproduces at the beginning of the dry season (November–December).
Anasa tristis is a true bug that feeds by sucking sap, mainly from the leaves, but sometimes also the fruit. Historically, at least as far back as 1902, some gardeners believed that A. tristis had toxic saliva, however more recent research from 1993 suggests the process of harming plants does not involve any toxins.
