The Lychee Erinose Mite (LEM) (Aceria litchii (Keifer)) is a gall-making eriophyid that feeds exclusively on lychee trees (Litchi chinensis Sonnerat), inducing the development of open leaf galls called erinea. Erinea are structures formed of hypertrophic leaf trichomes where LEM seeks refuge, feeds and reproduces.
