Smyrna blomfildia FABRICIUS, 1781



Blomfild's Bark Wing
Smyrna blomfildia FABRICIUS, 1781
Family - NYMPHALIDAE
subfamily - NYMPHALINAE
Tribe - NYMPHALINI

Introduction

The tribe Coeini comprises 6 genera - Colobura, Baeotus, Historis, Pycina, Smyrna and Tigridia.

There are 2 species in the genus Smyrna, namely karwinskii which is found in Mexico, and the more widespread blomfildia which is distributed from Mexico to Bolivia.

Habitats

This species is found in primary and secondary forest at altitudes between sea level and 1200m.

Lifecycle

(?)

Adult behaviour

Males of Smyrna blomfildia are often seen in aggregations of a dozen or more, imbibing mineralised moisture from rocky overhangs, stone walls, or tree boughs. They also visit fallen fruit on the forest floor, or in orchards.

When resting or feeding the butterflies usually keep their wings closed, but if disturbed they will flick them half-open momentarily. They are not nervous in disposition however, and in the presence of human intruders they will continue feeding long after most other species have fled.

In common with their relatives in the genera Colobura and Tigridia, they roost overnight on tree trunks, on which they are superbly camouflaged.

Februa Cracker - Hamadryas februa - HÜBNER, 1823




Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Nymphalidae
Sub-family: Nymphalinae
Scientific name: Hamadryas februa


Introduction:
There are 20 members of the genus Hamadryas, commonly known as Crackers due to the ability of the males of several species to produce a clearly audible sound which is similar to the crackling of bacon in a frying pan.

The sound is produced as the butterflies take off, and is made by twanging a pair of spiny rods at the tip of the abdomen against bristles on the valvae ( the male's anal claspers ). Only males can produce the sound, but both sexes can detect it - their wings have tiny hollow cells covered in membranes which vibrate in response to sound and stimulate nerve endings. The purpose of the sound is not fully understood : it may deter competing males from occupying the same territory, and may also act as a trigger to initiate the first response from a female during courtship.

Hamadryas butterflies use their ears to detect crackling noises made by territorial males. The sound is made by twanging 2 tiny prongs on the tip of the abdomen against bristles on the valvae. The males habitually bask on tree trunks, where they wait to intercept passing females.

All Hamadryas species have a beautiful calico pattern on the upperside. In many there is a series of submarginal ocelli on the hindwings, and distinct kidney-shaped stigmata in the discal cells of fore and hind wings. In several species such as februa and glauconome the ground colour is greyish and the pattern acts as an extremely effective camouflage against the bark of trees. In other species such as amphinome, laodamia and velutina the wings are velvety black with a blue sheen and a pattern of bright blue spots.

Most Hamadryas species are found only in Central and South America, although 8 have been recorded sporadically in the southern USA.

Hamadryas februa is the commonest and most widespread species, found from southern Texas to Uruguay and Paraguay.

Habitats:
This species is found in degraded rainforest and deciduous forest habitats, including orchards and the forested margins of cattle ranches, at altitudes between sea level and about 800 metres.

Adult behaviour:
In common with other Hamadryas species februa can often be seen basking on tree trunks, in a head-downward position and with the wings flattened against the bark. They will bask in this position for long periods to await potential mates. They commonly settle at a height of about 2 metres but if disturbed by humans they fly up and resettle higher up, either on the same tree or on another nearby. They remain high in the trees until the intruder leaves, and then descend the tree trunk in a series of short flights, dropping a short distance each time until after several minutes they resume their original position.

The butterflies are active from sunrise to sunset, and are rarely seen away from tree trunks, but also sometimes bask on rock faces or tree foliage. On a few occasions I have also seen them settling on the ground in lightly vegetated forest clearings.

Primrose Flag - Melete lycimnia - CRAMER, 1777



Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Pieridae
Genus: Melete
Specific name: Melete lycimnia


Introduction:
The Pieridae is divided into 3 subfamilies. The Dismorphiinae, with a very small number of exceptions, is entirely neotropical in distribution. The Coliadinae ( Sulphurs and Yellows ) and Pierinae ( Whites and Orange tips ) however have worldwide distribution.

There are 217 members of the Pierinae in the neotropical region. These include familiar Holarctic
( Eurasian and North American ) genera such as Pieris, Pontia and Anthocharis, and others such as Pereute, Catasticta and Melete which are found only in Central and South America.

The genus Melete contains 6 species, characterised by having a black bar at the end of the forewing discal cell, a black fw apex, and in most species a dark border to the hind-wings. Apart from these markings the wings are usually a unicolorous yellow or white.

Melete lycimnia occurs in several geographical forms. On the underside, subspecies peruviana has a white ground colour, narrow black borders, and a yellow spot at the base of the hindwings. At the other extreme the nominate subspecies lycimnia has the underside hindwings primrose yellow, with wide brown borders. In all subspecies the females are more yellowish in colouration than the males

Habitats:
This is a lowland rainforest species, occurring at elevations between sea level and about 800m.

Adult behaviour:
Males are a regular sight along forest edge habitats on the banks of rivers, and at roadsides, where they gather to imbibe mineral-laden moisture from sand or mud. They often congregate in dense clusters of 50 or more butterflies, packed very tightly together, which erupt nervously into flight if disturbed.

Females are not in my experience seen in such open situations, staying instead in the forest interior. They do not visit flowers in the understorey, or along forest roads, so presumably feed at the nectar of arboreal flowers. Their flight is direct and fairly rapid, interrupted by long periods at rest on foliage in the sub canopy.

Mcclungia cymo



Kingdom: Animalia

Order: Lepidoptera
(unranked): Rhopalocera
Superfamily: Papilionoidea

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...).

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.

Heliconius erato hydara - Hewitson, 1867(Crimson-patched Longwing)



Phylum: Arthropoda - Arthropods
Class: Insecta - Insects
Order: Lepidoptera - Butterflies and Moths
Superfamily: Papilionoidea - Butterflies (excluding skippers)
Family: Nymphalidae - Brushfooted Butterflies
Subfamily: Heliconiinae - Heliconians and Fritillaries
Genus: Heliconius
Species: erato
Sub Species: hydara


Introduction:
This widespread, geographically variable butterfly (see map 2 below) is involved in Müllerian mimicry with the concordantly variable Heliconius melpomene over most of its range. Only H. erato chestertonii Hewitson does not have a corresponding H. melpomene co-mimic. That race, from the upper Cauca valley of Colombia, is a co-mimic of H. cydno weymeri Staudinger.

Etymology: ERATO was one of the nine Muses, the goddesses of music, song and dance. Her name means "the lovely" or "beloved" from the Greek word eratos. In Classical times, when the Muses were assigned specific artistic spheres, she was named Muse of erotic poetry and mimic imitation and represented holding a lyre (ERATO).

Characteristics:
Early stages: Eggs are yellow and approximately 1.5 x 0.9 mm (h x w). Females usually place eggs singly on growing shoots of the host plant. Mature larvae have a white body with black and orange spots, black scoli, and yellow head; length is around 1.3 cm. Caterpillars are solitary (Brown, 1981). Pupae are brown with gold spots on the dorsum, the thorax is strongly bowed and has short abdominal spines. The head has long head horns and the antennae have many short black spines (Brown, 1981; DeVries, 1997).

Geographical Distribution:
Heliconius erato is widespread throughout Central America and South America. The map below shows an approximate representation of the geographic distribution of this species. The original data used to draw these maps are derived from Brown (1979) which is available at Keith S. Brown Jr. (1979). Ecological Geography and Evolution in Neotropical Forests.

Februa Cracker - Hamadryas februa - HÜBNER, 1823



Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
Family: Nymphalidae
Sub-family: Nymphalinae
Scientific name: Hamadryas februa


Introduction:
There are 20 members of the genus Hamadryas, commonly known as Crackers due to the ability of the males of several species to produce a clearly audible sound which is similar to the crackling of bacon in a frying pan.

The sound is produced as the butterflies take off, and is made by twanging a pair of spiny rods at the tip of the abdomen against bristles on the valvae ( the male's anal claspers ). Only males can produce the sound, but both sexes can detect it - their wings have tiny hollow cells covered in membranes which vibrate in response to sound and stimulate nerve endings. The purpose of the sound is not fully understood : it may deter competing males from occupying the same territory, and may also act as a trigger to initiate the first response from a female during courtship.

Hamadryas butterflies use their ears to detect crackling noises made by territorial males. The sound is made by twanging 2 tiny prongs on the tip of the abdomen against bristles on the valvae. The males habitually bask on tree trunks, where they wait to intercept passing females.

All Hamadryas species have a beautiful calico pattern on the upperside. In many there is a series of submarginal ocelli on the hindwings, and distinct kidney-shaped stigmata in the discal cells of fore and hind wings. In several species such as februa and glauconome the ground colour is greyish and the pattern acts as an extremely effective camouflage against the bark of trees. In other species such as amphinome, laodamia and velutina the wings are velvety black with a blue sheen and a pattern of bright blue spots.

Most Hamadryas species are found only in Central and South America, although 8 have been recorded sporadically in the southern USA.

Hamadryas februa is the commonest and most widespread species, found from southern Texas to Uruguay and Paraguay.

Habitats:
This species is found in degraded rainforest and deciduous forest habitats, including orchards and the forested margins of cattle ranches, at altitudes between sea level and about 800 metres.

Adult behaviour:
In common with other Hamadryas species februa can often be seen basking on tree trunks, in a head-downward position and with the wings flattened against the bark. They will bask in this position for long periods to await potential mates. They commonly settle at a height of about 2 metres but if disturbed by humans they fly up and resettle higher up, either on the same tree or on another nearby. They remain high in the trees until the intruder leaves, and then descend the tree trunk in a series of short flights, dropping a short distance each time until after several minutes they resume their original position.

The butterflies are active from sunrise to sunset, and are rarely seen away from tree trunks, but also sometimes bask on rock faces or tree foliage. On a few occasions I have also seen them settling on the ground in lightly vegetated forest clearings.

Malachite" - Siproeta stelenes LINNAEUS, 1758



Kingdom: Animalia
Phylum: Arthropoda
Class: Insecta
Order: Lepidoptera
(unranked): Rhopalocera
Family: Nymphalidae
Subfamily: Nymphalinae
Tribe: Victorinini
Genus: Siproeta
Species: S. stelenes
Binomial name: Siproeta stelenes (Linnaeus, 1758)


Introduction:
The tribe Kallimini includes the Asian Kallima ( Dead Leaf butterflies ), and the African genera Precis
( Pansies ) and Salamis ( Mother of Pearl 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.

The beautiful Malachite is distributed from Florida and Texas, south to Peru, Argentina and Bolivia. The butterflies look particularly beautiful when seen at rest, with sunshine streaming through the translucent green windows on the wings.

Some workers consider stelenes to be a Batesian mimic of the Heliconiine Philaethria dido. The 2 species generally occupy different habitats, but their avian predators probably encounter both species fairly regularly, so the theory may have some basis.

Habitats:
This is a widespread and common species found in a wide variety of habitats including lowland primary rainforest, mid-elevation cloudforest and deciduous forests, usually in the vicinity of rivers at altitudes between about 100-1200m. It is probably most commonly seen in secondary habitats, including orchards and gardens.

Lifecycle:
The eggs are dark green, and laid singly on leaves of Ruellia, Justicia or Blechum, all members of the Acanthaceae. Females tend to patrol back and forth along a limited stretch of habitat, dotting their eggs about fairly randomly.

The fully grown caterpillar is dark olive in colour, with a series of whorled spikes along the back and sides. Those on the back are reddish.

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

Adult behaviour:
The adults nectar at Lantana and other flowers, and also feed at fallen fruit, carrion and dung. I have seen groups of Malachites feeding on decaying fallen mangos in Costa Rica, and imbibing from gravel and tarmac roads in Peru and the Venezuelan Andes. They are usually seen flying in open sunlit areas, but I have on several occasions found them roosting beneath leaves deep in primary forest.

Ectima lirides Staudinger 1886


•Kingdom: Animalia - animals
•Phylum: Arthropoda - Arthropods
•Class: Insecta - Insects
•Order: Lepidoptera - Butterflies and Moths
•Family: Papilionoidea
•Genus: Ectima
•Specific name: lirides - Staudinger 1886
•Scientific name: - Ectima lirides Staudinger 1886

Introduction:
The Biblidinae are recognised by their diverse but simple and often colourful patterns. In the neotropics their representatives include the Ageroniina - a subtribe which includes the Hamadryas Crackers, the Ectima Banners, the Panacea Flashers and the Painted Beauty, which is the sole member of the genus Batesia.

Ectima and Hamadryas have much in common, not least their disposition for basking head-downwards on tree trunks with their wings held flattened against the bark. In common with the females of most Hamadryas species, Ectima have a band of white running diagonally across the forewings, but Hamadryas are larger, and have very intricate calico patterns on the upper surface, unlike the much plainer Ectima.

There are 4 Ectima species - erycinoides from Central America, thecla from southern Amazonia, lirides from Peru and Bolivia, and iona which is distributed from Colombia to the Mato Grosso.

Habitats:
This species is confined to primary rainforest at altitudes between about 200-800m.

Lifecycle:
The eggs are white and laid singly on new growth leaves of Dalechampia and other Euphorbiaceae.

The fully grown larva is black and covered with branched spines.

Adult behaviour:
The butterflies are nearly always encountered as singletons basking in the characteristic Hamadryas / Ectima fashion, head-downwards on tree trunks, either within dense forest or in orchards and other lightly forested habitats. They normally bask at a height of about 4 metres, but can be enticed lower down by applying liquefied plantain or fish paste to trunks at eye-level.
