Synophropsis lauri, sometimes called the bay leafhopper, is a species of leafhopper of the subfamily Deltocephalinae, tribe Fieberiellini. It is the only species in the genus Synophropsis.

Description

The hemelytra vary from greyish to brick-red (some sources say the males are grey, females re]) and are somewhat translucent with the veins showing up as whitish. The wings darken towards the tips. There are small dark marks along the suture and at the distal ends of some of the long veins. The head is yellowish and the vertex is sharply pointed. Antennae are filamentous and very long. Size: up to 6.5mm long, or even 7mm.

Nymphs are green, and over-winter. The species is normally said to be univoltine, but it is possible that the females hibernate and produce a second generation.

The species was first described, as Thamnotettix lauri, by Géza Horváth in 1897 from specimens taken in Fiume (Rijeka) and Buccari (Bakar) on the Adriatic coast of what is now Croatia. Nearly 30 years later, Hermann Haupt independently described a single male taken in Gravosa (Gruž), some 260 miles (420 km) further southeast. Haupt placed it in a new genus as Synophropsis wagneri. As these are now regarded as descriptions of the same species, Horvath's specific name has priority even though Haupt's new genus is accepted.

Throughout much of the 20th century it was regarded as a pontomediterranean species, i.e. inhabiting the area between the Black Sea (ho pontos to the ancient Greeks) and the Mediterranean. Since then it has expanded its range rapidly northwards and westwards. It has been known in France, initially Montpellier, since 1972, and in Switzerland since 2000. In 2008–09 it was discovered in Hamburg and Öhringen, two widely separated locations in Germany, and also at Liège in Belgium. It reached the London area in 2007, and has since been found elsewhere in the United Kingdom – the insect in the taxobox was seen in Cambridge in 2014.

Host plants

Synophropsis lauri is polyphagous on evergreen broad-leaved trees and shrubs. It was first described as frequenting, and takes its specific name from, the European bay laurel (Laurus nobilis). This tree, now cultivated far outside its natural Mediterranean range, is a favourite where available. In western Europe specimens of S. lauri have mostly been taken from ivy (Hedera helix). In Turkey S. lauri is listed as a minor pest of olive (Olea europea) groves. From  https://en.wikipedia.org/wiki/Synophropsis

A leafhopper is the common name for any species from the family Cicadellidae. 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. They undergo a partial metamorphosis, and have various host associations, varying from very generalized to very specific. Some species have a cosmopolitan distribution, or occur throughout the temperate and tropical regions. Some are pests or vectors of plant viruses and phytoplasmas. The family is distributed all over the world, and constitutes the second-largest hemipteran family, with at least 20,000 described species.

They belong to a lineage traditionally treated as infraorder Cicadomorpha in the suborder Auchenorrhyncha. This has sometimes been placed in its own suborder (Clypeorrhyncha), but more recent research retains it within Auchenorrhyncha.

Members of the tribe Proconiini of the subfamily Cicadellinae are commonly known as sharpshooters. From https://en.wikipedia.org/wiki/Leafhopper
