Abstract A terpenoid diol component of the pheromonal secretion of the queen butterfly was synthesized stereoselectively from geraniol by means of a site-specific terminal olefin functionalization and the subsequent anionic [2,3]-sigmatropic rearrangement of carbomethoxymethyl allylic sulfide.

Sex Pheromone of the Queen Butterfly: Electroantennogram Responses
Science, 1969Olfactory receptor responses (electroantennograms) were recorded from antennae of danaid butterflies. Antennae of male and female queen butterflies ( Danaus gilippus berenice ) respond equally strongly to the hairpencil of queen males, to its crude extract, and to one of its two identified secretory components (the ...

Sabotaging Behavior and Decision-Making in Larvae of the Queen Butterfly Danaus gilippus
Journal of Insect Behavior, 2015Sabotaging behavior and decision-making during ontogeny in herbivorous insects remain largely underappreciated. Insects that use hosts bearing articulated laticifers would be expected to cut trenches to deactivate this plant defense. Contrary to this expectation, larvae of Danaus erippus display vein cutting when feeding on Asclepias curassavica, a ...

Variation in Palatability of Queen Butterflies (Danaus Gilippus) and Implications Regarding Mimicry
Ecology, 1994This 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).

AbstractQueen butterflies do not mate until the male has brushed the tufts of his scented, abdominal ”︁hairpencils„ over the female's head and antennae. The trichogen cells located at the base of each hairpencil are secretory. Presumably, these cells produce the sex pheromone necessary for mating.

The structure of the antennae of the Florida Queen butterfly, Danaus gilippus berenice (Cramer)
Journal of Morphology, 1968AbstractInterest in the structure of the antennae of the Florida Queen butterfly arises from the finding that a pheromone is active in their courtship. Light and electron microscopic techniques were used to study the sensilla on the antennae and three types of sensilla with perforated walls were identified.

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

The cardenolide-based chemical defenses of danaine butterflies vary macrogeographically. This study demonstrates that these defenses also vary both microgeographically and temporally. We sampled 280 queen butterflies (Danaus gilippus) at 11 sites in northern Florida during the summer of 1993 and determined their cardenolide concentrations and thin ...

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
