Entomologist's Gazette, 2021 Examination of museum collections and field work have established that Danaus chrysippus once inhabited five of the seven Canary Islands but is probably now confined to La Palma, La Gomera and Fuerteventura. It may be extinct on Gran Canaria and Tenerife.

Sex Pheromone of the Queen Butterfly: Biology
Science, 1969 Males of the queen butterfly Danaus gilippus berenice , deprived of the two extrusible brushlike "hairpencils" at the rear of their abdomen, are capable of courting females but incapable of seducing them. In normal courtship, an aphrodisiac secretion associated with the hairpencils is transferred by way of tiny ...

Sabotaging Behavior and Decision-Making in Larvae of the Queen Butterfly Danaus gilippus
Journal of Insect Behavior, 2015 Sabotaging 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 ...

Sex Pheromone of the Queen Butterfly: Chemistry
Science, 1969 Two major components in the "hairpencil" secretion of the male of the queen butterfly ( Danaus gilippus berenice ) have been identified. One, a crystalline ketone (2,3-dihydro-7-methyl-1 H -pyrrolizin-1-one), is known from another danaid butterfly. The other, a viscous terpenoid alcohol (

Olfaction in the Florida Queen butterfly: Honey odour receptors
Journal of Insect Physiology, 1970 Abstract In an investigation of the role of olfaction in the life of the Florida Queen butterfly it has been found that honey odour can elicit proboscis extension. Selective blocking of antennal receptor types shows that only the short, thinwalled pegs are necessary for this response and only 5 to 10 per cent need be exposed for detection of honey ...

Journal of Morphology, 1971 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, 1968 AbstractInterest 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.

Journal of Insect Physiology, 1969 Abstract The chemo-stimulatory role of the male hair-pencils in the courtship behaviour of the Queen butterfly has been quantified experimentally in the natural habitat. Approximately 600 individuals were studied. Courtship success is substantially reduced either by removal of the male hair-pencils or by blocking the chemoreceptors on the female ...

Acta Biotheoretica, 1982 This paper presents a model that generates testable hypotheses concerning the evolution of long-range migratory behavior in the Monarch Butterfly,Danaus plexippus and the general absence of such behavior in a related form, the Queen,D. gilippus (Lepidoptera: Nymphalidae: Danainae).

Queen Ants Make Distinctive Sounds That Are Mimicked by a Butterfly Social Parasite
Science, 2009 Ants dominate terrestrial ecosystems through living in complex societies whose organization is maintained via sophisticated communication systems. The role of acoustics in information exchange may be underestimated. We show that Myrmica schencki queens generate distinctive sounds that elicit increased benevolent ...
