Species Account

For further information refer UK Moths.

Most of the records up to 2005 were recorded as Blastobasis lignea which has long been used for what is now known as Blastobasis adustella. Research by Karsholt & SInev in 2004 has concluded that the real lignea is in fact a species restricted to Madeira, and further complicated by the fact that lignea is now a synonym of Blastobasis vittata. Since 2008 vittata has occurred in several southern coastal counties, but as yet not recorded in Dorset.
