Cassiae Owlet - Opsiphanes cassiae - LINNAEUS, 1758

Surely you in TN, will be thinking I'm using the as excuse these are very rare butterflies, to post my worst macros! Well, Maybe you're right! :)

This is another "very strange to see butterfly". Is an insect very nervous and difficult to photograph. This photo is not made with macro focus mode, is made with normal focus and 20X zoom! (all optical zoom available in my bridge camera) I was lying in the rocky (and warn, because sun was very hot) ground for several minutes in order to take this shot. The butterfly landed to suck minerals from the sand, about 4.5 meters away from me. She flew up and landed on several times until I could make a couple of photos.

I have seen this butterfly before rarely, and never could take pictures. Interestingly, the area where I've seen is very specific, it is a dirt road at about 1000 masl, just where an underground water source emanates a little moisture to the sand of the road. Every time I go there at any time of year, is possible for me to see this butterfly even for a fleeting moment.

Thanks by stop and visit!


Kingdom: Animalia - animals
Phylum: Arthropoda - Arthropods
Class: Insecta - Insects
Order: Lepidoptera - Butterflies and Moths
Family: Papilionoidea
Group: Satyrinina
Subfamily: Brassolinae Tribe: Brassolini Genus: Opsiphanes
Specific name: cassiae

Identification: The Morphinae includes an estimated 140-150 neotropical species, 93 of which are placed in the tribe Brassolini. Of these, 73 are placed in the Brassolina - a subtribe which includes Blepolenis, Brassolis, Caligopsis, Catoblepia, Dasyopthalma, Dynastor, Mielkella, Eryphanis, Mimoblepia, Opoptera, Penetes, Opsiphanes, Orobrassolis, Selenophanes, and Caligo. All are crepuscular or nocturnal in behaviour, although a few species also fly by day in the darkest areas within their habitats.

The genus Opsiphanes comprises of 11 known species distributed variously from Mexico to Paraguay and Argentina. The butterflies are noted for their robust bodies, large heads and eyes. The forewing costa is strongly curved, and the termen slightly concave. In all species the upperside wings are earthy brown in colour with a diagonal orange band on the forewings starting midway along the costa and terminating at the tornus. The undersides of all species are a pale dingy hue, heavily marked with dark striations on the outer half of the wings, and marbled at the base. The hindwings also bear a very conspicuous mark in the form of an ocellus or swollen comma near the costa, and a smaller almost circular ocellus near the tornus.

Opsiphanes cassiae occurs from Mexico to Bolivia.

Life history: The eggs are globular, and laid singly, typically on the stems or dead leaf blades of the foodplants. The larvae feed, depending on species, on Heliconia ( Heliconiaceae ), Musa ( Musaceae ), Acroconia, Cocos, Bactris ( Arecaceae ) and probably other monocotyledons - coconuts, bananas, palms etc. The larvae are typically pale earthy brown in colour, with numerous fine dark lines along the back and sides. They have a pair of prominent caudal prongs, and their heads bear a crown of between 4-8 horns.

Habitat: This species is found in primary and secondary rainforest, at altitudes up to about 1000m.

Hello Jesus,
Another beautiful South American butterfly seeking moisture and minerals from the soil. You show the proboscis very clearly and the wing markings are beautiful. Great details and beautiful colours too.

Hola Jesus

Sigo viendo mariposas nuevas, pues si que hay cantidad de ellas diferentes. Esta es muy bonita, con ese movimiento o torcimiento del ala que parece en 3D, unos colores y anagramas estupendos. De envidiar es esta imagen.

Un saludo de Antonio

Hello Jesus,
This is a real beauty, how extraordinary the colors and patterns of the wings are! I think I would also lie on the ground to catch this wonderful creature. You are lucky, Jesus , to live in such a rich environment!
Thanks so much
Kind regards
