Issinae
Issidae is a family of planthoppers described by Spinola in 1839, belonging to the order Hemiptera, suborder Auchenorrhyncha superfamily Fulgoroidea. Distribution Species of this family are present throughout the Northern Hemisphere. Description Issidae are small insects generally with a stocky body, as the wings mainly develop in width. Basic body coloration is not striking, usually shows brownish colors. The head has two ocelli. The forewings have strong pronounced ribs. They wrap the abdomen when the insect is at rest. The family originally included approximately 1000 species with 215 genera, but the systematics of Issidae remains uncertain, with many of the subfamilies having been recently removed to separate families, including Caliscelidae. Nogodinidae, and Tropiduchidae. In 2013, scientists described a biologically unique set of mechanical gears in an ''Issus'' nymph, though identical structures are known in most planthoppers, and were known for decades before the fun ...

Hysteropterum
''Hysteropterum'' is a genus of planthoppers described by Amyot & Serville in 1843, belonging to the family Issidae, subfamily Issinae. Distribution Species of this genus occur in Europe and North Africa; the numerous New World species formerly assigned to this group have been reassigned to separate genera (e.g., '' Kathleenum''). Description The adult planthoppers reach of length, the basic coloration of their body is mostly pale brown or yellowish, with well drawn veins on wings. The females are usually bigger than the males.

Issus (planthopper)
''Issus'' is a genus of planthoppers belonging to the family Issidae of infraorder Fulgoromorpha of suborder Auchenorrhyncha of order Hemiptera. Like most members of the order Hemiptera (popularly known as the "bug" or "true bugs" order) they live on phloem sap that they extract with their piercing, sucking mouth parts. Planthoppers are the only animals known to possess a gear mechanism, and '' Issus coleoptratus'' is the first type of planthopper to have the mechanism formally described. 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, preventing yaw (rotation). Description The genus ''Issus'' includes small insects generally flightless with a stocky, brown body and forewings with strong pronounced ribs. They feed on phloem. Species of this genus are present in most of Europe, in the Near East, and in North Africa. Gear mechanism Planthoppers (of which th ...

Hemisphaerius
''Hemisphaerius'' is a genus of bugs in the family Issidae and tribe Hemisphaeriini. Species resemble the closely related ''Gergithus'': but are differentiated in this genus by the size of the frons Insect morphology is the study and description of the physical form of insects. The terminology used to describe insects is similar to that used for other arthropods due to their shared evolutionary history. Three physical features separate insec ... and shorter legs.

Hemisphaeriinae
The ''Hemisphaeriinae''Melichar L (1906) ''Monographie der Issiden. (Homoptera). Abhandlungen der K. K. Zoologisch-botanischen Gesellschaft in Wien.'' 3: 1-327. are a subfamily of bugs in the family Issidae, based on the type genus ''Hemisphaerius''. Species in 107 genera have been recorded in most continents, but the greatest diversity appears to be in South-East Asia. Tribes and Genera ''Fulgoromorpha Lists On the Web'' identifies four tribes: Hemisphaeriini Authority: Melichar, 1906 - currently thirty genera are listed from India, China, Indochina, Malesia through to New Guinea: ;subtribe Hemisphaeriina Melichar, 1906 * '' Ceratogergithus'' Gnezdilov, 2017 * '' Choutagus'' Zhang, Wang & Che, 2006 * '' Epyhemisphaerius'' Chan & Yang, 1994 * '' Gergithoides'' Schumacher, 1915 * ''Gergithus'' Stål, 1870 * ''Hemisphaerius'' Schaum, 1850 – type genus * '' Maculergithus'' Constant & Pham, 2016 * '' Neogergithoides'' Sun, Meng & Wang, 2012 * '' Neohemisphaerius'' Chen, Zhan ...

Gergithus
''Gergithus'' is a genus of planthoppers in the family Issidae. Like all planthoppers, adults feed on plant sap and are capable of escaping by leaping. The genus like other members in the tribe appears somewhat rounded and beetle-like, in some cases, with a mimetic resemblance to ladybird beetles. About 60 species are known in the genus and they are distributed in the Indomalayan and Palearctic Realms. Description The genus is closely related to ''Hemisphaerius'' but differs in having longer frons (forehead) and legs. The frons also lacks a median keel (carina) or tubercles on the frons, pronotum or mesonotum. The rounded tegmen which resembles the elytra An elytron (; ; , ) is a modified, hardened forewing of beetles (Coleoptera), though a few of the true bugs ( Hemiptera) such as the family Schizopteridae are extremely similar; in true bugs, the forewings are called hemelytra (sometimes altern ... of beetles are often patterned.

Baltic Amber
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014, 400 tonnes in 2015. "Baltic amber" was formerly thought to include amber from the Bitterfeld brown coal mines in Saxony ( Eastern Germany). Bitterfeld amber was previously believed to be only 20–22 million years old (Miocene), but a comparison of the animal inclusions in 2003 suggested that it was possibly Baltic amber that was redeposited in a Miocene deposit. Further study of insect taxa in the ambers has shown Bitterfeld amber to be from the same forest as the Baltic amber forest, but separately deposited from a ...
