Elachista lastrella Chrétien, 1896

on Bromopsis

mine

Long slender corridor at the underside of the lower leaves. Most mines ascend from the base of the leaf to the tip. Frass in a narrow continuous line, somewat off-centre. The sides of the corridor are very irregular, until, in the end, the mines has attained the width of the leaf. The larva makes 2 – 3 mines. Only the final mine is full depth, and then the frass lies in parallel chains. Wörz (1957a) described the corridor as running up and down, and found up to four larvae in a leaf.
