Wheeleria spilodactylus (the horehound plume moth) is a moth of the family Pterophoridae, first described by John Curtis in 1827. It is found in South-Western and Central Europe and the Mediterranean, Asia Minor and North Africa. It has been introduced to Australia as a biocontrol agent for white horehound (Marrubium vulgare).[1]
The wingspan is 20–. Adults are on wing from July to September depending on the location.[2]
The difficult to see larvae feed on black horehound (Ballota nigra) and white horehound.
