This species is rather similar to Acmaeops marginatus, Acmaeops pratensis and Acmaeops septentrionis.
Biology The life cycle lasts two years. The larvae develop under the loose bark, especially of oaks, aspens or apple trees. They are polyphagous wood borers in deciduous trees (Quercus, Pyrus, Acer, Fraxinus, Populus, Malus, Cornus etc.) They overwinter and pupate the following spring.
The adult beetles can be found from April to August feeding on pollen of valerians (Valeriana species), common hawthorn (Crataegus monogyna), elderberry (Sambucus species), sweet chestnut (Castanea sativa) and European pear (Pyrus communis).Jiři Zahradnik, Irmgard Jung, Dieter Jung et al.: Käfer Mittel- und Nordwesteuropas, Parey Berlin 1985,
