Arctostaphylos uva-ursi
The larvae feed on "Arctostaphylos uva-ursi" and "Vaccinium vitis-idaea". They mine the leaves of their host plant. The mine consists of a full depth irregular blotch mine. They only live as a leaf miner for a short period of time before leaving the mine to live freely among spun leaves. At this point they feed from within spun terminal shoots of their host plant. Larvae can be found from April to May.
