Main: (Crambidae / Pyraustinae)
63.007 [B&F: 1362] Pyrausta purpuralis (Linnaeus, 1758)

 

Notes: Found on chalk downland and dry, grassy areas, throughout much of Britain favouring very short turf. In Hampshire and on the Isle of Wight, locally common on the downs, and sometimes found in gardens where Thyme is grown. Wingspan 15-22mm. Flies by day and night. At first glance, confusable with P. aurata, from which distinguished by its larger size and the rounded leading edge to the dorsal cream spot on the forewing. The hindwing always has one or two yellow spots or short, broad streaks; this is best seen by viewing the underside of the moth. Also see the very similar P. ostrinalis for differences. Note that the purple scales apparent when freshly emerged quickly wear off and leave just a brown appearance. Larva feeds on Wild Thyme and Large Thyme and sometimes Corn Mint, living within a silken tube or tent.
