70.187 Eupithecia icterata (Tawny-speckled Pug) 1838
fw: 11-13mm; Jul-Aug; yarrow / sneezewort (Achillea millefolium / ptarmica), common throughout Britain
ID: Form subfulvata is easily identified by the large plain orange-brown forewing patch, contrasting sharply with the grey-brown costa and termen. Form cognata is less distinctive; it has strong white cross-lines and usually some hint of a tawny colour; its 'saddle' area is notably pale (whitish); it predominates in Scotland.
