Eupithecia haworthiata
Widespread but local in the Southern half of Britain scarce elsewhere, mainly nocturnal.
The caterpillars feed on Clematis vitalba and cultivated Clematis species.
The pupa hibernates and often 2 or even 3 winters are passed in this state.
The ground colour of the forewings is grey brown.
The crosslines are in pairs. A central spot is missing. There is a faint discal stain on the hindwings.
The colour of the first abdominal segments is strongly yellow, orange or reddish.
Adults fly during June & July in a single generation.
