History
There are three records. Lennon (1863) stated that it was not common, but that it had occurred near Glen Mills (VC73). Additional to MOGBI.
 
A few were attracted to MV at Abbey Burn Foot (VC73) in mid-August 1998. Lastly, one was trapped at Sorbie (VC74) on 18th August 2009.
 
Life cycle
One generation. Overwinters as an egg on the remains of the foodplant. Larvae are present during April to mid-July, mining the stem and then the roots of the foodplant. Pupation takes place underground among the roots.
 
There are plenty of stands of Butterbur across the region but finding the moth is a bit of an enigma.
 
Larval foodplants
Butterbur.
 
Identification
Rosy Rustic is similar but half the size, while Butterbur is brown without any pink.
 
Habitat
Mostly riverbanks, but also other places where Butterbur is found.
