Chestnut-coloured Carpet   

Thera cognata
Adult: 3
Resident, rare, very local. A northern species, including parts of northern England and Cumbria, found on moorland, hillsides and coastal rocky areas where juniper grows. In Scotland mostly in the far northern Highlands.


The small size with rather broad rounded chestnut-coloured forewings separate it from other geometrids. A key feature is the straighter inner edge of the wider central band.

Recording method

Only found near its foodplant juniper.  Comes to light.

Life cycle

One generation. Overwinters as a small larva during September to early June. Pupation takes place in a spinning among the leaves of Common Juniper.

Larval foodplants

Junipers, including garden varieties.


Caterpillars feed on Juniper, of which there is a sparce population in the region on coastal cliffs, moorland and a few other locations.
