Leaf discolouration and curling on a citrus tree. What is it?
Orange None Given
This is either an orange or a lemon tree. I can't recall which. It was planted about 6 months ago. It had been growing quite nicely and is actually flowering. But recently (in our Southern Hemisphere late autumn) this curling discolouration has occurred. It just occurs in a segment of the leaf and goes down to the central vein. The particular leaf I have photographed is viewed from front and back. You may also be able to see a slightly filmy appearance on the other side of the central vein. What is it? Thank you.
The leaf from the front.
Some flower buds and evidence of curling.
This is the same leaf from the back.
This is the citrus tree.

This is caused by a citrus leafminer. If you look closely at the end of one of the tunnels before they pupate and emerge from the leaf you will be able to find them. They usually move to the edge of the leaf and curl it over when they pupate.
