Host plant cited. Larval: Salix . Adult: Salix .

Biological remarks. The species replaces A. viridis on Salix in Tajikistan. Larvae bore individually or collectively under the bark or deeper in the wood of living branches ( Figs 9B, 9D, 9E ). Larval activity may cause dieback of infested terminal part (9C). The character of Salix infestation is similar to that of A. viridis in Europe ( Fig. 10C ) or A. politus ( Fig. 7D ) in North America.
