Species Account

The nominate subspecies trifolii doesn't occur in Kent, but the subspecies flava (known as the Pale Grass Eggar), is found at Dungeness, and nowhere else in the UK. The map below shows sporadic dots at other locations in Kent, but this species is only confirmed as breeding at Dungeness. Grass Eggar is a distinctive moth, large with brown wings and obvious white spots in the middle of the forewings. Pale Grass Eggar is much paler and therefore, despite its smaller size, could be mistaken at a glance for Oak Eggar. However, Grass Eggar and Pale Grass Eggar both have two crosslines whereas Oak Eggar has only one.

Record Verification

Grade 1 adults are generally distinctive and unlikely to be confused with other species, but records outside documented range or flight period may require photos.
