An adventive species of subtropical and tropical East Asia and Australasia likely brought in with cut flowers, also recorded in Sweden and Germany. Brought to Tony Pickles from Brockenhurst where it had emerged from a pupa in a cocoon on Chrysanthemum (cut flowers). See extensive discussion in Ent Rec Vol 117 pp131-132. Another was found in an office in Sandy, Beds on 14.12.01 where bunch of Chrysanthemums had been the day before. In lepiforum.de, it is mentioned that Haslberger et al. (2021: 31) point out that C. eriosoma, described from New Zealand and distributed in the Asian-Ocean region, is identical in barcode to C. chalcites and also differs from the latter only so marginally in its genitalia that its species status is questionable; in their opinion, the identity of the Bavarian specimens as this species is questionable. The same then also applies to the specimens from North Rhine-Westphalia and probably to Europe as a whole (including the specimen discussed here).
