70.187 Tawny-speckled Pug Eupithecia icterata (de Villers, 1789)

Common

Similar species: The forms of this moth with tawny central forewing markings are unlikely to be mistaken for other pugs, but there are northern forms without any tawny markings that are superficially similar to Grey Pug Eupithecia subfuscata which is on average smaller (10 to 12mm) and flies earlier in the year. These northern forms are also similar to Larch Pug Eupithecia lariciata and Golden-rod Pug Eupithecia virgaureata both of which have a darker thorax with white or pale crest or spot, rather than a pale thorax with dark or tawny colouring to the rear.

Forewing: 11 to 13mm

Habitats: Coastal downland, calcareous and acid grassland, open woodland, hedgerows, marshes, fens, sand-dunes, road verges and gardens.

Habits: The moth flies from dusk when it nectars at the flowers of Common Ragwort and Buddleia and comes to light.

Foodplant: The larva feeds on the flowers and leaves of Yarrow and Sneezewort and in gardens on Southernwood. It may also feed on Tansy. It pupates in loose soil.
