Strophosoma (Strophosoma) capitatum is a beetle from the family of the weevils (Curculionidae).
description
The beetle is 3 to 5.2 millimeters long. It has a broad trunk. The black wings (elytres) are covered with brown-bronze colored scales. Several rows of black dots run along the wings.
Distribution and way of life
The beetle species is widespread in Europe. Forests and open areas with trees are the habitat of the beetles. The fully grown polyphagous beetles can be found on a variety of trees: on pines , spruces and larches , on common Douglas fir and red beech , as well as on firs , birches , mountain ash and oaks . The beetles prefer to eat needles, leaves, buds and young shoots. In Denmark they cause feeding damage to the needles of Nordmann firs ( Abies nordmanniana ) and noble firs ( Abies procera ) in Christmas tree plantations and are considered to be forest pests . There are two periods of increased feeding activity in the year: in the spring before the eggs are laid and in late summer / autumn. The larvae feed on the roots of herbaceous plants such as heather ( Calluna vulgaris ).
Similar species
The black-spotted crown weevil ( Strophosoma melanogrammum ) is about the same size and looks very similar to Strophosoma capitatum . The most important distinguishing feature is the black line on the wings of S. melanogrammum .
