Citrus Leaf Miner

Description:

Unknown white markings on leaf caused by moth larvae.

Habitat:

Orange tree leaf

Notes:

"The larvae are considered a serious agricultural pest on Citrus species. They mine the leaves of their host plant. The mine consists of a long epidermal corridor with a well-marked central frass line. The mine is mostly lower-surface, but sometimes upper-surface, and rarely on the rind of the developing fruit. Citrus leaf miner larvae are thus protected from many topic insecticide treatments. Pupation takes place in a chamber at the end of the corridor, under an overturned part of the leaf margin." - Wikipedia
