Coronets, etc

1. Coronet, Marbled Coronet, Poplar Grey and Knot Grass dark noctuids with a light oval mark

2. Dot Moth, Black Rustic and Common Rustic agg. Dark noctuids with a light kidney mark

Coronet - a very variable species

Kidney mark is dark. A bright ‘coronet’ mark just below it

Often other markings are as bright as the ‘coronet’ mark.

Some forms are so dark that the  ‘coronet’ mark is not obvious

Poplar Grey

Marbled Coronet

Similar to the Coronet but the Oval mark is part of a white band going halfway across the forewing

Note : There is also a Varied Coronet in which the white band through the Oval mark goes right across the forewing

Knot Grass

1 or 2 white marks on each forewing next to the trailing edge

Often has marks similar to Knot Grass but marks not pure white and usually more than two on each forewing

Common Rustic agg.,Black Rustic, Dot Moth,

There are 3 moths- Common Rustic, Lesser Common Rustic and Remm’s Rustic - which it is generally accepted are too variable and too similar to be told apart except by dissection so they are usually referred to jointly as Common Rustic agg.


A mallet-shaped mark behind the head - not always distinct.

Centre of the kidney mark lighter than the rest of the forewing.

Tip and outer edge of the forewing gently rounded.

Common Rustic agg. They are very variable but the aggregate group have marks in common which distinguish them from other species.

Black Rustic

Dot Moth

A small orange protrusion usually visible.

The Coronet and Common Rustic groups are very variable. There are a number of other species which are easily recognisable themselves but that the above moths could be mistaken for.

Black Rustic and Dot Moth are given here as examples that black forms could be mistaken for.
