Lime-speck pug

Lime-speck Pug (Eupithecia centaureata) is a species of moth in the family Geometridae. It is found across the Palearctic region, including Europe, North Africa, and Asia, extending to the western parts of North America. This moth is known for its distinctive lime-green speckles on its wings, which camouflage it against the foliage of its preferred habitats. The Lime-speck Pug is a nocturnal species, primarily active at night when it feeds on the nectar of various flowers.

Description

The Lime-speck Pug has a wingspan of 17-22 mm. The forewings are grey or brown with a distinctive greenish-white speckling and a small, dark discal spot. The hindwings are paler with a faint discal spot and darker venation. The larva is slender, green or brown, with fine, light longitudinal lines and a darker head.

Habitat

This species is versatile in its habitat preferences, thriving in a wide range of environments including gardens, hedgerows, woodland edges, and open countryside. It has a particular affinity for lime trees (Tilia spp.), which are both a food source for the larvae and a nectar source for the adults.

Life Cycle

The Lime-speck Pug has one or two generations per year, depending on the climate. In warmer regions, it may produce a second generation in late summer. Eggs are laid on the flowers and leaves of the host plant. The larvae feed on the flowers and developing seeds of a variety of plants, with a preference for lime (Tilia) and other trees and shrubs. After pupating, the adult moths emerge, ready to mate and continue the cycle.

Conservation Status

Currently, the Lime-speck Pug is not considered to be at risk. It is widespread and common in many parts of its range. However, like many species, it could be affected by habitat loss and changes in agricultural practices.

In Culture

While not as widely recognized as some of its more colorful relatives, the Lime-speck Pug is appreciated by moth enthusiasts and naturalists for its subtle beauty and the role it plays in the ecosystem as a pollinator.
