73.360 [B&F: 2127] Triple-spotted Clay (Xestia ditrapezium) ([Denis & Schiffermüller], 1775)


Local, in damp, broad-leaved woodland and fens, from Kent and East Anglia to Devon, in Wales and in central and west Scotland. In Hampshire and on the Isle of Wight it is very rare, with only three records since 1989, the last being at Shortheath Common in 2008. Wingspan 39-46mm. Pattern very similar to that of Double Square-spot X. triangulum, but the colour of the forewing is a more intense, redder brown, more heavily suffused with fuscous, and the hindwing is relatively paler (MBGBI Vol 9). A specimen of this species must be retained for the record to be considered for acceptance. A photograph is NOT considered sufficient for the purpose. In autumn, larva feeds on herbaceous plants such as Primrose, Dandelion and Dock, and in spring on buds of Sallow, Dogwood and other woody plants.
