Schrenck’s emperor butterfly

Mimathyma schrenckii belongs to Nymphalidae, subfamily Apaturinae. Apatura schrenckii and Adolias schrenckii are historical generic combinations. [2]

A broad pale band crosses the hindwing, while separate white markings occupy the forewing. Orange markings occur toward the inner forewing region. [1][2]

Korean records include wooded mountains and valleys. A male in the Kyungpook National University collection was collected on Mt. Bangtae, Gangwon, on 29 June 1998, at 400 m elevation. [2][3]

The Korean treatment describes one annual brood, with adults from mid-June to early September. Larvae are solitary and usually overwinter in the third instar, sheltered on their food plants. [2]

Korean hosts include Ulmus davidiana var. japonica, U. parvifolia and Zelkova serrata. Russian records include Carpinus cordata and Ulmus laciniata. [2]

Males are encountered along streams and forest paths, where they visit fermenting fluids. Afternoon circling above trees is also recorded. Females are less often observed at these feeding sites. [2]

The broad hindwing band, separate white forewing marks and orange inner-forewing details provide the principal pattern landmarks. [1][2]

The broad pale band and smaller white forewing marks remain distinct within dark wing fields. Restrained internal lines preserve their boundaries. [1][2]

Protect the specimen from handling, bright direct light and moisture. A closed enclosure reduces dust accumulation around the fragile wing edges.

How does it overwinter in Korea? Larvae usually spend winter in the third instar, sheltered on their food plants. [2]

Which adult behaviour is recorded? Males visit fermenting fluids beside streams and forest paths and may circle above trees in the afternoon. [2]

The Korean Apaturinae treatment documents larval development, hosts and adult behaviour. Harvard and Kyungpook National University collections provide identified specimens and locality records. [1][2][3]
