25-55 mm. European species, threatened in the north and west of its range due to the continuing disappearance of ancient oak woodland. Found throughout Hungary, and locally common. Characteristic of old oak trees in natural and planted environments, such as city parks. In Hungary known from sweet chestnut (Castanea sativa), turkey oak (Quercus cerris) English oak (Qu. robur), sessile oak (Qu. petraea) and downy oak (Qu. pubescens). Prefers trees exposed to sun. The larvae feed beneath the bark for two years and then spend a further two years deep in the heartwood, where they pupate in a characteristic chamber. The adults emerge from their pupae in the autumn of the fourth year but do not emerge from the tree until the following May. Thereafter adults can be seen until August. Several generations may develop in a single trunk, causing accelerated deterioration of the wood. Adults spend the day either in their tunnels or on trunks and in wood piles. Flies occasionally in the afternoon, but mainly active at night. Mating takes place on the trunk. Adults feed on tree sap.
