[Nyctaginaceae:] Abronia latifolia [= Abronia arenaria] (Gelbe Sandverbene)
[Nyctaginaceae:] Abronia umbellata (Rosa Sandverbene)

Powell (1991: 102-103) züchtete seinen Holotypus und die meisten Paratypen von Abronia latifolia. Er schreibt aber: "Lithariapteryx elegans is almost exclusively an insect associate of beach foredune communities. It depends upon Abronia latifolia, an active sand dune invader, but uses A. umbellata on stabilized sand where it grows near A. latifolia. The type locality consisted of chaparral-covered stabilized dunes in the 1960's, and A. latifolia in the vicinity presumably was limited to foredunes to the west that I did not visit. With increasing off-road vehicle (ORV) activity, extensive sand roads and active sand invaded the Oso Flaco Lake area by 1971; the active sand gradually increased its takeover of dune vegetation during 1971-77 (see photos, Powell 1981), when A. latifolia became prevalent and the collections of L. elegans were made. In 1980 the California State Park System gained control of the area, which had been operated as a county park, and beginning in 1982 excluded further ORV activity at the Oso Flaco Lake site. By 1987, when only fragments of natural vegetation survived in the active sand dunes where L. elegans lived in the 1970's, a revegetation project was initiated by planting two species of native grasses. The exclusion of vehicular traffic and the planting / irrigation project evidently provided sufficient stabilization that, despite four successive dry years, colonization by a variety of native plants has been successful, including Abronia latifolia and A. umbellata. Hence, we can expect survival of L. elegans at the type locality."
