Rediscoveries and Presumed Extinctions of Hawaiian Leaf-roller Moths (Lepidoptera: Tortricidae).
Presumed extinct. This species is known only from the male holotype, supposedly reared from leaves of Lysimachia hillebrandi var. venosa [=L. venosa] (Primulaceae) by Swezey in 1932 on the “Kalalau Trail” at an elevation of 3800 ft. The collecting site may refer to the trail leading down from the Kalalau Lookout at Kōkeʻe State Park. Zimmerman (1978) listed Lysimachia glutinosa as an additional host, but we are not sure of his justification, as we are only aware of the holotype for this species. Perhaps Zimmerman (1978) believed Swezey’s initial plant identification was incorrect; Lysimachia venosa is an exceedingly rare species, known only from three specimens from the summit of Waiʻaleʻale (Marr and Bohm 1997) until its rediscovery in 2012 (Wood 2013). On the other hand, Lysmiachia glutinosa occurs somewhat commonly along the upper portion of the trail leading down from the Kalalau Lookout at Kōkeʻe State Park (KAA pers. obs.).
