Detail
The most common European species of this genus which inhabits both natural biotopes and quite artificial formations like city parks, gardens, alleys etc. up to 800 m. A western Palaearctic species reaching Scandinavia and preferring forest steppes and light oak forests on slopes. Eggs are deposited on the bark of thin twigs of the host plants (usually 1 – 3 cm) and covered with a whitish secretion. Depending on the diameter of the twig, larvae bore straight or slightly zig-zag tunnels parallel with the axis of the twig towards the trunk (in thin twigs) or middle-aged larvae turn back and both parts of the tunnel are nearly parallel (in wider twigs). Before pupation, the larva turns its tunnel at a right angle and build its pupal chamber just under the bark or partly in the bark (if the bark is thick enough). Forming this last curve, larva cuts the phloem issues and pupa is protected in this way against superfluous humidity. The development lasts one year, pupation in April – June. Females prefer thin, terminal twigs of old oaks for oviposition, but all branches or trunks of young oaks can be also infested. Host plants: Carpinus betulus, Castanea sativa, Fagus sylvatica, Ostrya carpinifolia, Quercus cerris, Q. coccifera, Q. conferta, Q. frainetto, Q. ilex, Q. mirbecki, Q. petraea, Q. pubescens, Q. robur, Q. suber (Bílý, 2002).
