Grammoptera ustulata, a widely distributed Euro-Anatolian species of oak forests, has been described as Leptura ustulata from Halle environs (Germany) by Johann Gottlob Schaller in 1783 [❖]
G. ustulata, analogously to Grammoptera abdominalis, develops in rotten branches of deciduous trees attacked by a fungus Vuilleminia comedens. The larvae of this species feed centrally in the branches and later they create pupal cells perpendicular to the branch axis. The pupal cell leads directly under the bark surface and is not secured by any wad of frass as it is common in other Cerambycidae. The preferred habitat of this species are oak woods growing on south facing slopes of river valleys in Central Europe [✳][✮]. Adults, active from late April to July, are diurnal and anthophilous.
Body length: ♂♂ 5 - 7 mm / ♂♂ 6 - 9 mm Life cycle: 1 year Adults in: end of April - July Host plant: polyphagous on deciduous trees, associated with a fungus Vuilleminia comedens (prefers oaks - Quercus spp.) Distribution: Europe, Caucasus, Transcaucasia, Turkey
The depicted beetles were: ♂ - reared from larva found in dead oak (Quercus robur) branch in Jaroslav village environs (Pardubice district, Pardubice region, East Bohemia, Czechia) in February 2005; ♀ - beaten from blossoming hawthorn in Pohansko chateau environs (Břeclav district, South Moravia, Czechia) on May 9, 2003.
