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

Hypna clytemnestra CRAMER, 1777



Hypna clytemnestra CRAMER, 1777
Family - NYMPHALIDAE
subfamily - CHARAXINAE
Tribe - ANAEINI

Introduction:

The genus Hypna contains just one species.

The upperside is black, with broad creamy white bands across the forewings. Like most members of the Charaxinae, it has a cryptic underside pattern, resembling a dead withered leaf.

Hypna clytemnestra occurs from Mexico to Argentina.

Habitats:
This species is found in the Amazonian lowlands and Andean foothills, at altitudes between about 100-1200m.

Lifecycle:
The eggs are globular, and laid singly on the foliage of Croton ( Euphorbiaceae ).

The fully grown caterpillar is pale brown, with a prominent thoracic hump, and has reddish tubercules along the back, from which long black setae arise.

Adult behaviour
The butterfly is uncommon, and always encountered singly. It appears to spend most of it's life high in the trees, and can usually only be observed from a distance through binoculars. Occasionally a butterfly will descend however, attracted by rotting fruit or sap runs, and at such times it often first settles on nearby foliage.

Siproeta epaphus



Siproeta epaphus LATREILLE, 1813
Family - NYMPHALIDAE
subfamily - NYMPHALINAE
Tribe - VICTORINIINI

Introduction:

The Kallimini includes some of the most colourful and instantly recognisable species in the world. Amongst them the African genera Precis ( Pansies ) and Salamis ( Mother of Pearl butterflies ), and the Asian Kallima ( Dead Leaf butterflies ).

In the neotropics the tribe is represented by the genera Anartia, Junonia, Hypolimnas, Metamorpha, Napeocles and Siproeta.

The genus Siproeta comprises of 3 species - the Malachite stelenes, the green-banded superba, and the Rusty-tipped Page epaphus. All are large butterflies, with wingspans averaging 10 cms.

Siproeta epaphus occurs throughout Central America from Mexico to Panama, and in South America occurs in Venezuela, Trinidad, Brazil, Ecuador and Peru.

Habitats:
This species is scarce in lowland areas, but commonly seen in two's and three's in disturbed habitats at elevations between 400-2000 metres, favouring forest edges, roadsides, cattle pastures, and well vegetated riverbanks..

Lifecycle:
The eggs are dark green with yellow ribs, and laid in small clusters on the leaves of the foodplant.

The fully grown larva is maroon, adorned with orange branched spikes along the back and sides. The head is black with a pair of backward-curving horns. The larvae feed on the foliage of Ruellia or Blechum ( Acanthaceae ).

The chrysalis is pale green, with the thorax and abdomen covered in minute black dots, and is suspended by the cremaster from stems of the foodplant.

Adult behaviour
The butterflies are usually encountered in two's and three's, flying on sunny mornings in open situations, but can also be found in hazy or misty conditions, basking on foliage or bare ground.

They have a rapid fluttering and gliding flight, and commonly visit flowers in pastures, along forest edges, and along roadsides. Males often imbibe mineralised moisture from damp roads, muddy riverbanks, scree or rock faces, and at such times usually hold their wings half-open while flitting gently from spot to spot.
