Description

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 the leaf. The pupa is attached to a leaf without a cocoon.

Distribution

It has a nearly cosmopolitan distribution and has been recorded from Russia, Ukraine, Georgia, southern Kazakhstan, Kirgizia, Uzbekistan, nearly all of Europe, the Middle East, Africa, India, Japan, North America, Australia, New Zealand and Oceania.

gollark: AMD ones are at least accurate to about 20%.
gollark: Even the 10-core ones get TDPs of 100W or so at most even though they happily draw 300.
