Consequently, I am able to identify which species are ‘likely migrants’. It’s never an exact science, although Eudonia angustea and Turnip Moth usually show an increase here in numbers when ‘obvious migrants’ are trapped. Quite often the Turnip Moth will show an increase in numbers when Dark Sword-grass arrive – perhaps travelling together?

White-point I consider a ‘resident’ here as frequently caught when the traps are devoid of migrants. However, numbers are occasionally bolstered when migration events occur. I also catch the odd L-album Wainscot out of season, I have two clearly defined broods here of this now well established species. This suggests to me a primary immigrant, so migrants do turn up of resident species.
