This species can be found in most of Europe, east into Russia. It is also known from China (Heilongjiang, Xinjiang), Korea and Japan (Hokkaido). [1][3]

Description

The wingspan of Prochoreutis myllerana can reach 10–14 mm. [4] Forewings are variegated brown, with a dark brown median fascia showing white dusting. These moths are characterized by 2 + 2 white dots on the upper part of the wings, near the edge.

Prochoreutis myllerana is very similar to Prochoreutis sehestediana, [4] but in the latter the white dusting extends more than half way towards the costa of the forewings and the mentioned 2 + 2 white dots are missing. [4] The apex of P. sehestediana is more pointed. [5] Moreover in P. mullerana head of larvae is uniformly pale brown, contrary to Prochoreutis sehedestediana. [6]

Biology

Adults are on wing from May to early September.[4] There are probably three generations per year. [4] The monophagous larvae feed on Scutellaria galericulata and Scutellaria minor. [4] The young larvae mine the lower leaves of their host plant. Older larvae live free among spun leaves. There are also records on Lamium album and Lamium purpureum, [1] but these need confirmation. [6] Full grown larvae can be found in June and July – August. Probably these moths hibernate as adults. [6]

gollark: That's probably one of the nice times when it won't be as bad, then.
gollark: Then you get the *fun* and *excitement* of dealing with buffer overflow issues.
gollark: If it was an actual char vector thingy, it would not be null terminated.
gollark: In sane languages, instead of being null-terminated, a string is basically a byte vector/array/whatever which has an actual length, reducing all the buffer overflow problems and making it so you can get lengths without iterating over the whole string.
gollark: Er, null termination.
