This spectacular longhorn beetle is one of the most important insect pests of trees in Central Asia. It can frequently be found in avenues or parks in highly urbanised areas. Adults usually leave their pupation cells in April or the beginning of May and are crepuscular and nocturnal. During the daytime, they hide under the bark, in larval galleries, and in other refuges. They leave the hideout at dusk, males appearing first, and move about until morning on the surface of the particular tree on which they developed. T. sartus does not fly much and maturation feeding has not been observed.
