Marbled Knot-horn

A scarce species, less frequently recorded than <i>A. suavella</i>, which shares the same foodplant.&nbsp; It is rather less predominately coastal than that species and is found - thinly - right across the county.

Grey Knot-horn

Widespread and fairly common across the county, in numbers that can vary significantly from year to year, perhaps being absent from the Levels.

Thicket Knot-horn

A fairly common species that seems to be prone to boom-and-bust cycles of abundance.&nbsp; Although it seems to occur across the county, the vast majority of records are coastal.&nbsp; It comes to light, including in gardens.

Acrobasis suavella
