Lygus gemellatus is a species of plant-feeding insects in the family Miridae.[1]

Distribution and habitat

This species is widespread in most of Europe and in the Oriental ecozone.[2] These bugs can be found mainly along roadsides and on meadows.[3]

Description

Lygus gemellatus, museum specimen

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]

Biology

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]
