Lime-speck Pug Eupithecia centaureata
([Denis & Schiffermüller], 1775)
Wingspan 16-20 mm.
A distinctive and slender-winged Pug, it is thought that this species may resemble a bird-dropping and thus reduce attraction to predators.
Fairly common throughout Britain, occurring in a wide range of habitats, the species has one or two broods, being found on the wing from April to September.
The caterpillars feed on the flowers of a range of low-growing plants.
