13 new moths were found during the Moth Night



Acrobasis advenella

Wingspan 18-24 mm.


Distributed widely throughout much of Britain except the far north, preferring areas of old uncut hawthorn hedge, this species is reasonably common.


It has one brood, which flies in July and August, when it often is a visitor to the light-trap.

Agriphila tristella

Wingspan c.27 mm.

Another common grassland species throughout Britain, and fairly distinctive with its pale yellowish or creamy longitudinal streak which branches into 'fingers' towards the wing tip.

Flying from June to September, it is nocturnal and a regular visitor to the light-trap.

The larvae feed in the base of stems of grass.

Argyresthia goedartella

Wingspan 10-13 mm.

This is one of the commonest moths in the genus Argyresthia.

Flying at night and on sunny afternoons from June to August

Batrachedra praeangusta

Wingspan 14-15 mm.


This small, inconspicuous species is locally common in England and Ireland.


It can be found in a wide range of habitats, where the larvae feed on the catkins and leaves of poplar (Populus) and sallow (Salix).


The nocturnal adults, which have elongated narrow forewings, fly during July and August.
