Dinoptera collaris belongs among the most common European species and frequent flower visitors, occurring not only in preserved natural localities, but often also in cultural landscape, parks and gardens. The larvae live under the loose bark of dead trees, branches, trunks, surface roots and create galleries filled by frass. They can move freely on the surface. Before the second overwintering, the mature larvae enter the soil, where they hibernate in the created pupal cells, and in the spring they pupate. Adults occur from May to July (peak at the turn of May and June) on many different flowers, blossoming trees and bushes.

Body length:6 - 9 mm
Life cycle:2 years
Adults in:May - August
Host plant:polyphagous in deciduous trees (Quercus, Pyrus, Acer, Fraxinus, Populus, Malus, Cornus etc.)
