Gorse Shield Bug

Lat. “Piezodorus lituratus“
species of family “Stink Bugs“
1 species

Piezodorus lituratus, also known as the gorse shieldbug or gorse seed bug, is a species of shield bug found in Africa, Europe, Northern Asia, and North America. They inhabit various habitats with host plants, preferably dry and warm environments with sandy soil. The adult bugs come in two color forms, green in the spring and purplish-red in late summer. Mating occurs from May to July, and the females lay their eggs on host plants. Common broom and dyer’s greenweed are the main host plants, along with other legumes. The species is listed in the red list of Swedish species and can be distinguished from the green shieldbug by its habitat and red antennae.

Varieties
#

Piezodorus lituratus var. lituratus (Fabricius, 1794) Piezodorus lituratus var. alliaceus (Germar, 1823)

Distribution
#

This species is present in Africa, in most of Europe, in Northern Asia (excluding China) and in North America.

Habitat
#

These shield bugs live in many habitats where host plants are present. They prefer dry and warm habitats, especially with sandy soil.

Description
#

Piezodorus lituratus can reach a length of 10–13 mm (0.39–0.51 in). These large shieldbugs occur in two adult colour forms. In the spring when they emerge and mate they are predominantly green, while the new generation that appears in the late summer has purplish-red markings on the pronotum and corium. In autumn they have a much paler color, prior to hibernation they may become darker, but after hibernation they are bright green.In Piezodorus lituratus var. alliaceus the corium shows a uniform yellow-greenish color. This species could be confused with the green shieldbug, Palomena prasina, but Piezodorus lituratus has a different habitat and red antennae.

Biology
#

Mating takes place from May to July, the females lay 10 to 20 eggs on the stems, leaves and fruits of the host plants. The nymphs occur until September. The adults of the new summer generation can be found from the end of July or beginning of August. Hibernation occurs in the imago stage. The main host plants are various legumes (Fabaceae), especially common broom (Sarothamnus scoparius) and dyer’s greenweed (Genista tinctoria), but also alfalfa (Medicago sativa), vetches (Vicia species), sweet-clover (Melilotus species), crown vetches (Coronilla species) sainfoins (Onobrychis species), lupin (Lupinus species) and others.
