Notes. Despite being one of the most ubiquitous species of Lepidosaphes in the United States, and across the world, L. ulmi has apparently not been collected in the Florida landscape since 1921 and more recent records of the species are all from interceptions of propagative material ( Dekle 1965; FDACS-DPI database). When it was collected, it was apparently restricted to the northern panhandle in Baker and Duval counties ( Dekle 1965). For a comparison of L. ulmi with L. pinnaeformis see the “Notes” section of the latter.
