leaf miner trail showing entrance and exit points


The name leaf miner is a genaral term used for certain moth, beetle, and fly larvae that tunnel between the upper and lower surfaces of leaves. Eggs are laid on the underside of immature leaves. The larvae from the hatched eggs eat the leaf tissue between the upper and lower leaf surfaces, leaving behind a near-transparent trail in a characteristic pattern. If the affected leaf is torn in two, it can be seen that the leaf is hollow. After feeding, leaf miners drop off the leaf to pupate underground or under cover of plant debris.
