Barbitistes constrictus

Eastern saw bush-cricket

Description

Eastern saw bush-cricket Barbitistes constrictus is a species of bush-cricket (family Tettigoniidae) found in Europe. It is relatively common in parts of Europe, particularly in Central and Eastern regions. It primarily inhabits coniferous forests and wooded areas. Barbitistes constrictus insect feeds on various tree species, often causing damage to young trees by feeding on their needles and leaves, buds, and shoots. While not typically considered a major pest, large populations can sometimes cause significant defoliation in forests, impacting tree growth. The adults are green or brownish, with long antennae and strong hind legs for jumping. It has one generation per year. Females lay eggs in late summer or early autumn. The eggs hatch in spring, and the emerging nymphs go through several molts as they grow. These nymphs resemble smaller versions of the adults but lack fully developed wings. The adult stage occurs in summer, when Barbitistes constrictus becomes fully winged and sexually mature.
