Variation in Palatability of Queen Butterflies (Danaus Gilippus) and Implications Regarding Mimicry

Ecology, 1994
This study documents the existence of a food plant related palatability spectrum in Florida queen butterflies (Danaus gilippus). Abdomens of butterflies reared on four asclepiad food plants differed significantly in cardenolide content and palatability to a generalist avian predator (Red—winged Blackbird).

Palatability of aposematic queen butterflies (Danaus gilippus) feeding onSarcostemma clausum (Asclepiadaceae) in Florida [PDF]

Journal of Chemical Ecology, 1991
Queen butterflies (Danaus gilippus) are generally considered unpalatable to predators because they sequester and store toxic cardenolides from their larval food plants. However, a major queen food plant in Florida, the asclepiadaceous vineSarcostemma clausum, is shown here to be a very poor cardenolide source, and queens reared on this plant contain no

Evidence for Interspecific Competition in Natural Populations of the Monarch and Queen Butterflies, Danaus Plexippus and D. Gilippus Berenice in South Central Florida

Ecology, 1962
Daia us plexippus (Linne) and Danauis gilippus berenice (Cramer), the Monarch and Queen butterflies, overlap broadly in their ecological requirements (Brower 1961a). Further evidence of their similarity was indicated by comparative laboratory analyses of egg cannibalism (Brower 1961b), developmental rates, and food consumption (Brower in prep ...

Differences and similarities in cardenolide contents of queen and monarch butterflies in florida and their ecological and evolutionary implications

Journal of Chemical Ecology, 1985
Florida queen butterflies are highly variable in cardenolide content and, in three populations studied, contained less cardenolide than did a sample of sympatric Florida monarchs. The possibility that queens stored a more potent set of cardenolides from their host plants (and therefore were as well protected as monarchs, even at lower concentrations ...

Insecticide Poisoning as a Possible Cause of an Aberration of Pupation Behavior in the Florida Queen Butterfly

Annals of the Entomological Society of America, 1968
During the summer of 1967 at the Archbold Biological Station in Lake Placid, Highland Co., Fla., we were raising many Florida queen butterflies, Danaus gilippus berenice (Cramer). For this work, we collected eggs and larvae primarily from the locally abundant queen butterfly larval food plant, Asclepias tuberosa rolfsii.

Unpalatability of viceroy butterflies (Limenitis archippus) and their purported mimicry models, Florida queens (Danaus gilippus)

Oecologia, 1991
Understanding the dynamics of defensive mimicry requires accurately characterizing the comparative palatability of putative models and mimics. The Florida viceroy butterfly (Limenitis archippus floridensis) is traditionally considered a palatable Batesian mimic of the purportedly distasteful Florida queen (Danaus gilippus berenice). I re-evaluated this

Revising a Classic Butterfly Mimicry Scenario: Demonstration of Mullerian Mimicry between Florida Viceroys (Limenitis archippus floridensis) and Queens (Danaus gilippus berenice)

Evolution, 1991
Batesian and Müllerian mimicry relationships differ greatly in terms of selective pressures affecting the participants; hence, accurately characterizing a mimetic interaction is a crucial prerequisite to understanding the selective milieux of model, mimic, and predator.
