Two immigrant macro-moth species were new to Britain in 2020: Rusty-shouldered Pug from the Dorset coast and, perhaps more unexpectedly, Parallel Lines from an inland locality in Cambridgeshire; there was also the first British record of the pyrale Acrobasis fallouella recorded from a site in coastal West Sussex. Vagrant Emperor arrived in good numbers for the second successive autumn. There were also a number of high late summer/autumn counts of Migrant Hawker, some of which may have been the result of continental influxes. Multiple records of Norfolk Hawker in the Radipole area of Dorset represent one of the more notable Odonata events of the year. Migrant butterflies fared less well in general, one of the highlights being a Queen of Spain Fritillary.
