Grammoptera 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.

Body length:5 - 9 mm
Life cycle:1 year
Adults in:end of April - July
Host plant:polyphagous on deciduous trees, associated with a fungus Vuilleminia comedens
Distribution:Europe, Caucasus, Transcaucasia, Turkey

The depicted beetles were beaten from a blossoming hawthorn (Crataegus) and oak (Quercus robur) near Srbsko village (Central Bohemia, Czech Republic).
