Description

Family: Geometridae (ABH : 70.150)

Wing span: 18 - 20mm

This moth is similar to the Foxglove Pug, but is smaller and has neater markings. The central cross-band on the fore-wing is is gently curved near the leading edge. The dark patch at the base rarely extends into the trailing half. The central cross-band is usually dark grey.

It is quite well distributed throughout most of England and Wales. It is local and scarce in Scotland.

Habitats are rough chalk and limestone grassland. Also broken ground and derelict land, often in urban areas, and gardens.

There are one or two generations from late May to early September. It over-winters as a pupa.

Larvae feed on the flowers and seeds of Common Toadflax and probably Purple Toadflax. They will accept Snapdragon in captivity.

It comes to light but is seldom seen by day.
