Calamobius

Calamobius

*Calamobius* Guérin-Méneville, 1847 is a slender, grass-dwelling longhorn found across southern and central Europe, North Africa, Turkey, and the Caucasus. Adults are active in spring, resting on grass stems in a characteristic posture on warm, dry meadows rich in tall grasses such as *Arrhenatherum elatius* and *Dactylis glomerata*. The female bites a hole near the upper part of the stem, just below the spikelet, then reverses and deposits a single egg; the larva bores downward through the stem toward the root. The genus holds the distinction of being the only Cerambycidae recorded as a pest of cultivated cereals in the region.
