Callambulyx tatarinovii

Appearance

The wingspan is 56–82 millimetres. It is very similar to "Smerinthus kindermannii", but the forewing colours are predominantly green and grey although there is a northern form in which all green coloration is replaced by brown.

Naming

*"Callambulyx tatarinovii tatarinovii"
⤷ "Callambulyx tatarinovii formosana" - Clark, 1935
⤷ "Callambulyx tatarinovii gabyae" - Bryk, 1946

Distribution

It is found from northern Xinjiang across northern China, Mongolia, southern Siberia to the Russian Far East and Japan, and then south through Korea and central China to eastern Tibet. It is also found in Taiwan.

Behavior

There are one to two generations per year in China. In Korea, adults are on wing from early May to mid-October.
The larvae have been recorded feeding on "Ulmus parvifolius" in Guangdong and "Zelkova" in northern China. Other recorded food plants in China include "Euonymus alatus", "Salix", "Populus" and "Prunus persica", but these require confirmation. In Korea, recorded host plants include "Ulmus davidiana" var. "japonica", "Zelkova serrata", "Tilia amurensis" and "Euonymus sieboldianus", while "Ulmus japonica" is recorded for the Russian Far East. Subspecies "C. t. gabyae" has been recorded feeding on "Zelkova serrata".
