Closterotomus biclavatus is a species of plant bug found in most of Europe. They are commonly found in trees and bushes, wet forests, edge rows, and spruce forest edges. Males can reach a length of 5.5-7 millimeters, while females range from 6.5-7.6 millimeters. They have a black or dark brown body with brown or dark brown legs, and a distinctive enlarged blackened apex of the second antennal segment. Nymphs can be found in June, while adults are present from late June to September. They feed on a variety of trees and shrubs, including blackberries, birch, hazelnut, honeysuckle, blueberry, common ash, and small insects. They overwinter as eggs and have one generation per year.
Subspecies
#Closterotomus biclavatus biclavatus (Herrich-Schäffer, 1835)
Closterotomus biclavatus dalmatinus (Wagner, 1957)
Distribution and habitat
#This species is present in most of Europe. The preferred habitats are trees and bushes, wet forests, the edge rows, and spruce forest edge.
Description
#Closterotomus biclavatus can reach a length of 5.5–7 millimetres (0.22–0.28 in) in males, of 6.5–7.6 millimetres (0.26–0.30 in) in females. The color of the body is quite variable, usually black or dark brown, the legs are brown or dark brown. The species can be recognized (even in young specimens) for the enlarged apex of second antennal segment which is blackened.
Biology
#Nymphs can be found in June, while adults are present from late June up to September. These plant bugs are polyphagous, feeding on several species of trees and shrubs. They mainly feed on blackberries (Rubus sp.), birch (Betula sp.), hazelnut (Corylus avellana), common honeysuckle (Lonicera periclymenum), blueberry (Vaccinium myrtillus), common ash (Fraxinus excelsior) and also on small insects. They overwinter as eggs, with just one generation per year.
