Classification
| Family: | Geometridae |
| Subfamily: | Larentiinae |
| Genus: | Thera |
| Species: | juniperata |
| Authority: | (Linnaeus, 1758) |
Common on chalk downland and in gardens, in much of southern England, North Wales and Cumbria, less commonly on moorland in upland areas of Scotland. Since the 1960s increasingly reported on cultivated juniper species in gardens throughout much of England and Wales. In Hampshire and on the Isle of Wight very local on downland, but despite occasional records elsewhere, there is no real evidence that the species is taking to cultivated junipers in gardens, as it is in some other parts of the country. Wingspan 26-29 mm. The main confusion species is Cypress Carpet T. cupressata, but Juniper Carpet lacks the series of darks streaks near the apex of the forewing. Larva feeds on Juniper, especially Prostrate Juniper in upland areas, over-wintering as an egg.
