Panacea prola Doubleday [1848]



Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Nymphaliae
Subfamily: BIBLIDINAE
Tribe: AGERONIINI
Genus: Panacea
Specific name: prola - Doubleday [1848]
Scientific name: - Panacea prola Doubleday [1848]

Introduction:
The genus Panacea contains 3 known species, all confined to the neotropics.

The underside hindwings of all Panacea species are reddish. In P. procilla the hue is dull reddish brown, overlaid with broken wavy black lines and a series of submarginal ocelli. In regina the underside is red, with a suffused pattern of blackish markings.

The species featured here - Panacea prola, is smaller than regina and has a bright red underside that is devoid of markings. The iridescent bands on the upperside appear as a highly reflective pale turquoise when viewed from directly above in bright sunlight. In overcast conditions, when viewed at certain angles, the colour changes to a beautiful shade of sky blue.

Panacea prola is found throughout much of South America, from Colombia to southern Brazil but is more abundant in the foothills of the eastern Peruvian Andes than anywhere else.

Habitats:
This species appears to be confined to rainforest and transitional cloudforest, at altitudes below about 1000m. It becomes increasingly abundant at lower altitudes, and can be extremely common below 500m in certain areas, e.g. in the forests of the Manu in southern Peru.

Lifecycle:
Surprisingly the lifecycle and larval foodplants of this common butterfly are apparently unknown.

Adult behaviour:
The butterflies roost amongst foliage high in the forest canopy. In the early morning they can be seen basking on tree trunks at a height of about 10-15 metres, head downwards, with wings flattened against the bark of the tree.
As temperatures begin to climb and light levels increase, they gradually descend to bask at lower points on the trunk, but will fly back to bask much higher up if disturbed. Later, even the weather remains cool and overcast, they descend to settle on riverbanks, often settling on rocks, stones, or logs. Once the butterflies have been on the ground for a few minutes they become very reluctant to move, and will remain basking until dusk, even during light showers or drizzle.

Argia oculata - Hagen in Selys, 1865



Foto tomada en la quebrada de "María la O", Cerro la Copa, Montalbán Carabobo....

La cópula de los Odonatos del suborden "Zygoptera", es uno de los comportamientos más peculiares de todo el reino animal. Ésta, empieza por el "agarre" por parte del macho de una hembra; la abraza con sus cercoides (apéndices prensiles situados al final de su cuerpo) por el cuello. A continuación, el macho pasa su esperma del extremo de su cuerpo, donde los crea, a una concavidad situada al principio de su abdomen; la hembra se dobla hasta introducir su órgano sexual en dicha concavidad donde el macho ha alojado sus espermatozoos produciéndose la inseminación. Esta postura ha dado lugar al símbolo que los humanos utilizamos para representar al "corazón"... ¿Curioso, no?...

Para aquellos que ya conocen sobre Zygopteros, quiero aclarar que la especie "Argia oculata" (en la foto), no presenta diformismo sexual en coloración (ó es tan leve que no llega a notarse a simple vista). Así que puedo asegurarles que no se trata de dos "machos" (afortunadamente, je je je...).

Saludos

Rothschildia lebeau





Kingdom: Animalia (Animals)
Phylum: Arthropoda (Arthropods)
Class: Insecta (Insects)
Order: Lepidoptera (Butterflies and Moths)
No Taxon: (Moths)
Superfamily: Bombycoidea
Family: Saturniidae (Giant Silkworm and Royal Moths)
Subfamily: Saturniinae (Silkmoths)
Tribe: Attacini
Genus: Rothschildia
Species: Lebeau (Guérin-Méneville, 1868)

IDENTIFICATION:
Identification: Wings are reddish brown with an olive tinge. Upperside of forewing has large clear spots that touch or pass through the postmedian band. Postmedian band on each wing is irregular with a narrow white band.

LIFECICLE:
Adults emerge in the early evening, and mating occurs from about 10 PM to midnight. Egg-laying begins the following evening and continues over several nights, with the females laying eggs in rows of 3-6 on the host plants. Young caterpillars feed in groups while older ones are solitary feeders. The cocoon hangs on a twig during the winter, attached by a strong silken stem.

Caterpillar hosts: A wide range of native and introduced plants including lime prickly ash (Zanthoxylum fagara), Mexican ash (Fraxinus berlandieriana), willow (Salix), peach (Prunus persica), citrus (Citrus), and acacia (Acacia).

Adult food:Adults do not feed.
