“…This is the case in heliconiid butterflies, which synthesise cyanogenic glycosides (Nahrstedt & Davis, 1983;Ackery, 1987). It is also possible that A. bredowii obtain the defensive chemicals from adult feeding sources as documented in Ithomiinae butterfly species (Brown, 1987) but there is no evidence that this is likely.…”

Abstract. 1. A laboratory bioassay experiment was performed in order to investigate a long-standing putative mimetic relationship between two butterflies, the Lorquin's admiral Limenitis lorquini and the California sister Adelpha bredowii (Lepidoptera, Nymphalidae). These butterfly species are commonly sympatric in their broad distribution on the west coast of the United States. The wing colour pattern of L. lorquini differs from the patterns exhibited by its North American congeners, resembling A. bredowii instead.2. The feeding responses of California scrub jays Aphelocoma californica (Passeriformes, Corvidae) to these prey types and a known palatable control, the buckeye butterfly Junonia coenia (Lepidoptera, Nymphalidae), were examined quantitatively. The birds usually demonstrated long handling times of A. bredowii before consumption, while L. lorquini was manipulated and consumed at the same rate as the control butterfly. The birds also exhibited feather ruffling and bill wiping after consuming A. bredowii while they did not exhibit such behaviours after consuming L. lorquini and J. coenia.3. The birds did not discriminate between the dorsal colour patterns of the two species in a choice experiment.4. Because A. bredowii was moderately unpalatable to the captive scrub jays and the birds were not discriminating in their choice, this suggests a Batesian mimetic relationship between L. lorquini and A. bredowii.

“…(Verbenaceae) and concluded that flowers of this species are critical for maintaining the community of Lepidoptera visitors. In this study, we focused on the species A. brasilianum and E. intermedium, belonging to genera regularly visited by Lepidoptera (Brown Jr., 1984a;1987;.…”

“…The high number of Ithomiinae species may be due to the richness of Eupatorium (at least 11 species), in addition to the occurrence of A. brasilianum. Ithomiinae evolved the ability to assimilate pyrrolizidine alkaloids (PAs) from the nectar of these Asteraceae and transform them into compounds required to complete their life cycle (Brown Jr., 1984a;b;1987;Trigo et al, 1996;Paiva & Barata, 2004). This illustrates the importance of Asteraceae plants in maintaining butterfly populations in a given vegetation formation.…”

RESUMO Riqueza de espécies de borboletas antófilas de um fragmento de Mata Atlântica no Sudeste do BrasilOs objetivos do presente trabalho foram identificar borboletas antófilas em flores psicófilas de quatro espécies de Asteraceae em um fragmento de Floresta Atlântica, no município de Viçosa, Minas Gerais, Sudeste brasileiro, e determinar se existem espécies de borboletas em comum com outros levantamentos Species richness of anthophilous butterflies of an Atlantic Forest fragment in Southeastern BrazilThe objectives of this study were to identify anthophilous butterflies on psychophilous flowers of four Asteraceae species in an Atlantic Forest fragment in Viçosa, Minas Gerais State, Southeastern Brazil, and to determine whether there are species in common with other lepidopteran inventories of the Southeastern and Midwestern regions of Brazil. It is the first inventory of anthophilous butterflies of a semideciduous forest fragment in Zona da Mata, State of Minas Gerais. A total of 108 species were recorded, representing the fourth largest lepidopteran survey in this State. The results demonstrated that Asteraceae species may be important tools for monitoring anthophilous butterflies. The similarity with other inventories ranged from 1 to 92.55%. Fifteen species were reported for the first time in the State of Minas Gerais, and among them, Melanis alena and Thisbe irenea were observed in this study only.

“…The possibility that multi species aggregations in insects and other animals is associated to the occurrence of large concentrations of food resources in some sites (hypothesis 2) has been advanced by several authors (Bradbury 1981;Bradbury & Gibson 1983;Beehler & Foster 1988;Brown 1992). Adult ithomiines usually visit many different flowers to obtain nectar and pyrrolizidine alkaloids (Brown 1985(Brown , 1987Brown et al 1991;Trigo et al 1996). In many cases, it is possible to observe many individuals belonging to different species on a single, very attractive plant, but studies relating the spatial abundance of plants visited for pollen or larval host plants (constituted mainly by Solanaceae and Apocynaceae; see Drummond & Brown 1987;Freitas 1993) and the formation of Ithomiine pockets remain scarce.…”
