Saperda punctata

Saperda punctata is a polyphagous longhorn beetle whose larvae develop mainly in dead trunks and thick branches of deciduous trees. Rarely can be seen also on branches and stams of declining trees. It shows a strong preference for elms (Ulmus spp.), but has also been recorded from oaks (Quercus spp.) and willows (Salix spp.). The species is nocturnal and adults appear from May to August. The life cycle lasts one to two years, with larvae overwintering under the bark before pupating in sapwood. Though rarely abundant, its larval activity can reduce the vitality of ornamental trees in urban areas. In Europe, it is widespread but vulnerable in regions where mature elm trees have declined due to Dutch elm disease.
