  • You definitely have leaf miners! Skeletonizers. You may have also had some nibbling by a rodent? But leaf miners is what you've got. These guys are right. Sorry? – stormy Sep 20 '19 at 18:54

This damage is what's known as 'skeletonized' - it's usually caused by insect larvae that eat between the veins of a leaf, leaving behind this typical 'lacework' look to the leaves. Later, once it becomes an adult, it usually disappears altogether. This is not the same thing as leaf miners - those leave what looks like a trail inside the leaf tissue, rarely causing this skeletonized effect - the larvae which have done this could just as easily have been under or on top of the leaves. Quite which insect has caused the problem is hard to say - have a good look at the leaves, including the backs, as well as the stems with a magnifying glass to see if you can find any larvae or insects anywhere, but its possible they've all gone already. https://www.gardeningknowhow.com/plant-problems/pests/insects/skeletonized-plant-leaves.htm
