This thoroughly illustrated book compiles information from about 1000 literature sources, plus BugGuide submissions and my own observations, to present keys to the leaf mines found on each plant genus in North America. Species accounts (biology, hosts, and distribution) are given for each insect species, and the first 383 pages are devoted to introducing leafminers (biology, terminology, rearing) and providing overviews of each group of leaf-mining insects as well as their parasitoids and predators (including photos of adults).

The first edition was released as a self-published e-book in 18 monthly installments (January 2018 - June 2019) and the second edition is now being distributed on a similar schedule. For purchase and subscription information, see this page.
