Lygus gemellatus is a species of plant-feeding insects in the family Miridae. [1]
This species is widespread in most of Europe and in the Oriental realm. [2] These bugs can be found mainly along roadsides and on meadows. [3]
Lygus gemellatus can reach a length of 5.5–6.2 millimetres (0.22–0.24 in) in males, of 5.2–5.7 millimetres (0.20–0.22 in) in females. [3] These bugs are usually pale grayish green, sometimes with brownish or reddish tinge. Black spot on scutellum usually are bifid apically. [4] However, in this species color and of dark patterns on pronotum and scutellum shows high variability. [5] Corium has black spots at the margin and cuneus has a black distal angle. Membrane is smoke gray, with yellowish-gray veins. Legs are yellowish-gray to brown. Femora have two distal black rings, while tibias show black thorns. [6]
These plant-feeding insects have two annual generations. They overwinter as imago. Adults can be found from June to September. They are polyphagous and develop on a large scale on agricultural crops, damaging mainly the cereal and leguminous crops. They also feed on Artemisia vulgaris (juices), on Tanacetum vulgare (nectar) and on Medicago sativa . [3] [7]
The Miridae are a large and diverse insect family at one time known by the taxonomic synonym Capsidae. Species in the family may be referred to as capsid bugs or "mirid bugs". Common names include plant bugs, leaf bugs, and grass bugs. It is the largest family of true bugs belonging to the suborder Heteroptera; it includes over 10,000 known species, and new ones are being described constantly. Most widely known mirids are species that are notorious agricultural pests that pierce plant tissues, feed on the sap, and sometimes transmit viral plant diseases. Some species however, are predatory.
The genus Lygus includes over 40 species of plant-feeding insects in the family Miridae. The term lygus bug is used for any member of genus Lygus.
The tarnished plant bug (TPB), Lygus lineolaris, is a species of plant-feeding insect in the family Miridae. It has piercing-sucking mouthparts and has become a serious pest on small fruits and vegetables in North America. It is considered a highly polyphagous species and feeds on over half of all commercially grown crop plants, but favors cotton, alfalfa, beans, stone fruits, and conifer seedlings. A study done in southwestern Quebec, Canada has investigated the presence of L. lineolaris in a commercial vineyard. This study also indicated that weeds that grow from cultivation of crops serve as an important food source for L. lineolaris. This insect can be found across North America, from northern Canada to southern Mexico. Adults grow up to 6.5 mm in length, and are brown with accents of yellow, orange or red, with a light-colored "V" on the back (dorsal). The genome has recently been sequenced for the first time.
Carpocoris mediterraneus, the red shield bug, is a species of shield bug in the family Pentatomidae.
Adelphocoris lineolatus, is commonly known as the Lucerne bug or the alfalfa plant bug, and belongs to the family Miridae. It is an agricultural pest causing vast amounts of damage to numerous crops, but primarily to alfalfa crops around the globe.
Stenotus binotatus is a species of plant bug, originally from Europe, but now also established across North America and New Zealand. It is 6–7 mm (0.24–0.28 in) long, yellowish, with darker markings on the pronotum and forewings. It feeds on various grasses, and can be a pest of crops such as wheat.
Deraeocoris schach is a species of plant bugs belonging to the family Miridae, subfamily Deraeocorinae.

Adelphocoris rapidus, common names for which are rapid plant bug or superb plant bug, is a species of Hemiptera in the family Miridae, that can be found everywhere in the United States, and in the Peace–Athabasca Delta, Canada. The species are larger than other members of the family, and are either yellowish-black or orange-black coloured.
