Ectropis crepuscularia

Small engrailed

Description

Ectropis crepuscularia, commonly known as the small engrailed, is a moth whose fully grown caterpillars reach a length of 32-38 mm. It inhabits woodlands, gardens, and parks. As a polyphagous species, the caterpillars feed on various woody plants, including oak (Quercus spp.), beech (Fagus spp.), and birch (Betula spp.). The moth typically has two generations per year, with adults flying in spring and summer. In cooler climates, there may only be one generation, with adults appearing in May. Caterpillars are active throughout the growing season, and the species overwinters as a pupa. Though Ectropis crepuscularia is common and widely distributed across Europe and extends into the Far East of Asia, it is not considered a major economic pest. However, it can occasionally cause defoliation in forests or ornamental trees, leading to localized damage.
