From my forthcoming book on HK moths:
Global distribution: China (Hong Kong, Hainan).
H.K. distribution & status: widespread, common.
H.K. ecology: recorded from March to early November, possibly in four generations (peaks occur in late march to mi-April, mid to late June, late July through August and late September to early October).
Taxonomy: listed by Holloway (1983) as Narosoideus vulpina? (Wileman, 1911), a species known from China (TW, GD, SC, YN) (Wang et al., 1981; Wang, 1995a). Narosoideus vulpina lacks a black discal f/w stigma, has the h/w paler than the f/w, a less prominent f/w medial fascia and much less uniformly brown colouration of the f/w. The Hong Kong / Hainan Miresa species is closely allied to Miresa argentifera Walker, 1855.
