Citrus leaf miner is most common during summer and autumn and can affects all citrus. The grub tunnels inside new leaf growth, forming a silvery pattern and distorting the leaves. The new affected leaves look like they have melted a bit and roll up.
Heavy infestations will stunt growth, but rarely kill a tree. Damage can be controlled by cutting off the affected parts and spraying with homemade oil spray to deter the moth from laying eggs. Put pruned branches in the rubbish bin.
