Leafminer species in NYC

.
To quote the Wikipedia article on leaf miners, "A leaf miner is any one of a large number of species of insects in which the larval stage lives in, and eats, the leaf tissue of plants."

If you are not yet familiar with leafmines, but are curious to see some, start looking carefully for white squiggly lines or whitish blotches on leaves of all various kinds of plants, both wild and cultivated.

On this page I am compiling a list of the leaf miner species that I have observed in NYC. The species identifications are almost entirely thanks to the generosity and brilliant ID-ing work of leafminer expert Charley Eiseman, @ceiseman.

Just a reminder here that leaf mining is an ecological niche, not a taxon. All leaf mines are created by insect larvae, but as Charley points out: "In North America [leafminers] include at least 40 families of moths, 10 families of flies, 6 families of beetles, and 2 families of sawflies." It's also worth saying here that despite the common name, sawflies are not flies; instead they are related to wasps.

Most of the leafminers on this list are larvae of small flies, but so far I have observed several that are moths (microlepidoptera), one which is a chrysomelid beetle, and one which is a sawfly. The taxa other than flies I have put in boldface.

Leafminers in a leatherleaf holly species, which I assume is the American Holly?
