What is "parum"

Parum is a genus of moths in the Sphingidae family, containing only one species, Parum colligata, which is found from Korea and Japan south throughout eastern and central China and Taiwan to Vietnam, northern Thailand and north-eastern Myanmar.

The wingspan is 69–90 mm. There are one or two generations per year in northern China, with adults on wing from May to July. Farther south, there may be up to four generations. Adults have been recorded from mid May to late September in Korea.

The larvae have been recorded feeding on Broussonetia kaempferi, Broussonetia papyrifera and Morus alba in Guangdong. Other recorded foodplants include Broussonetia kazinoki and Maclura fruticosa.
