Distribution: This is one of Europe's rarest species. It flies in
small widely spaced colonies in parts of extreme NE Greece, FYROM (Former
Yugoslav Republic of Macedonia) and
Bulgaria. There are a significant number of records from Finland (several dozen)
indicating that it arrives here as a regular, if infrequent, migrant. I don't know
where they originate from.
Identification: Resembles the other Bath Whites and the Dappled
Whites. Follow this link for the to the
Flight time: Double brooded flying in early May and mid June.
Habitat: The habitat is
distinctive. The foodplant only appears to grow on regularly disturbed
pebbly places that generally occur at rivers and streams where periodic
water flows prevent extensive growth of plants.
Behaviour: I've only ever found this species once and that was just before
a huge rainstorm that lasted all day. So I have no so little experience with this
