Leioderes kollari, a broadly distributed but not common European species inhabiting forests, parks, and anthropogenic biotopes as well as semi-open areas, has been described from Austria by Ludwig Redtenbacher in 1849 [▽].
According to Rejzek and Rébl [❖] the preferred host of this species in Central Europe is field maple (Acer campestre). Thicker branches and trunks are usually attacked. Larvae feed subcortically and later in sapwood creating a very characteristic frass pattern filled with fine sawdust. When entering the wood the larvae never block the entrance holes. They secure the pupal cells by a wad of frass deeper in the wood. The beetles can occasionally be found on flowers but they probably gather on them during the night and stay there a substantial part of the next day, analogous to their close relative Leioderes tuerki, a typical nocturnal species. Leioderes tuerki is not active before dusk and during the night it flies around cordwood and comes to flowering plants, shrubs and trees. During the next morning it can for example be found sitting on flowering hawthorn, but it disappears before noon. Most of the beetles spend the day sitting on leaves of the host plants (Juglans regia and others in case of Leioderes tuerki).
Body length: 9 - 15 mm Life cycle: 1 - 2 years Adults in: May - June Host plant: polyphagous in deciduous trees (Acer, Ulmus, Quercus) Distribution: Albania, Austria, Belarus, Bosnia and Herzegovina, Bulgaria, Croatia, Czechia, France, Germany, Greece, Hungary, Italy, Latvia, Montenegro, North Macedonia, Norway, Poland, Romania, Russia, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Ukraine
The depicted beetleswere reared from larvae collected in dead field maple (Acer camperstre) in Křivoklátsko Protected Landscape Area (Central Bohemia, Czechia) and in Hungary.
