(3)Food
Larvae feed on leaves of mistletoe,
Phoradendron spp.
Remarks
In a study of another mistletoe-feeding species, the Great Purple Hairstreak, the larvae of
Emarginea percara were found to be heavily preyed upon by the bordered plant bug
Largus cinctus and predatory stink bug
Podisus acutissimus (Whittaker, 1984).
E. pallida was "redefined as a very pale desert form of
E. percara known from the deserts of southeastern California, southernmost Nevada, and western Arizona" in Lafontaine & Schmidt (2015).
