The juniper carpet (Thera juniperata) is a moth of the family Geometridae. It is found throughout Europe and the Near East, but is rather uncommon and locally distributed, mainly due to its very specific larval food plant. The nominate race has a wingspan of 26–29 mm but smaller races occur in Ireland and Scotland. The forewings are light brown with a darker shaded band and a very distinctive black apical streak. The hindwings are pale buff. It is active at night from September to November, but rarely flies any great distance though it occasionally comes to light.
