Northern Spinach Geometridae

Eulithis populata (Linnaeus, 1758)

Description: Wingspan 33-40mm. The forewings are generally yellow with a darker brown central band and basal patch. Adults rests with the abdomen curled up.

Similar Species: Confusion is possible with the Chevron Eulithis testata, but this is usually redder in general colour and has a later flight period.

Key Identification Features:

Sets:  male upperside

Flight Period: From mid-June to early August.

Status: Widely distributed, and most commonly encountered in southern counties. Baynes described this moth as common in Ireland but until the mid 1990s it would have been more appropriate to define its status in N. Ireland as scarce. Increased fieldwork in the last few years, especially in the west, has produced many new sites.

Ecology: Found mainly in mature woodlands, bogs and upland heathland. Adults are attracted to light in small numbers. The larvae feed on Bilberry Vaccinium myrtillus. It overwinters as an egg.

World Distribution: Across Europe and Asia to eastern Siberia.

Bradley & Fletcher number: 1756 Agassiz number: 70.091
