The wingspan
is 8–10 mm.
The larvae feed on Calystegia pubescens, Calystegia sepium
, Convolvulus althaeoides
, Convolvulus arvensis
, Convolvulus siculus, Convolvulus tricolour, Ipomoea batatas and Ipomoea purpurea
. They mine
the leaves of their host plant. The mine starts as a narrow tortuous corridor with a central frass
line, that often cuts off part of the leaf. Later, larvae leave the mine and begin to make a series of full depth fleck mines. Pupation takes place outside of the leaf. The pupa is attached to a leaf without a cocoon.
