Status and Distribution
Rare, recorded from four sites in south and south east England.
Foodplant and Larval Feeding Signs
The foodplant is unknown in Britain.
In Europe it was suspected it could be associated with Quercus (oak) or Castanea (sweet chestnut) but in Sweden it has been found in localities where neither of these trees are present.
In 2012, a female was bred in Poland from a larva found on Salix caprea, Baran, T. (2013). This is treated, in that paper, as the first trustworthy foodplant preference for this species.

Finding the Moth
Adult: comes occasionally to light.
Similar to T. luculella, which has broader forewings distally and pale yellow to yellowish-white markings which curve to make a semi-circle touching the costa (leading edge) at both ends. T. flavimaculella has less extensive orange markings in this area.
A form of T. luculella lacking the whitish markings has been found on one occasion in Hampshire in 1969.
Single brooded with only a limited number of records (eight) suggesting a flight period from mid-May to late July.
