Value of species
European species preferring lowlands and low, warm escarpments up to 500 m. Single eggs are deposited on the bark of branches or trunks of living willows of the diameter 1 – 20 cm (usually 2 – 5 cm). Larva bores an undulate tunnel in sapwood (rarely in phloem). Total length of the tunnel is usually 65 – 80 cm, exceptionally 1 – 1,2 m. Terminal part of the tunnel is sunk into the heartwood where the larva builts the pupal chamber (in larger diameters a pupal chamber is situated in the sapwood). Development lasts two years, pupation in May or June, adult beetles come out in June – August with the maximum in July. Host plants: Salix aurita, S. caprea, S. cinerea, S. eleagnos, S. fragilis, S. incana, S. purpurea, S. viminalis. This species prefer solitary, sunexposed willow trees on meadows and adults often flock together at the very top of the trees (Bílý, 2002).
