This one is for My Friend Goutham (goutham_ramesh) who came all the way from Amsterdam for this butterfly

Greta oto is a brush-footed butterfly, and is a member of the clearwing clade; its wings are transparent. Its most common English name is glasswing, and its Spanish name is espejitos, which means "little mirrors." Indeed, the tissue between the veins of its wings looks like glass. It is one of the more abundant clearwing species in its home range, which extends throughout Central America into Mexico. The opaque borders of its wings are dark brown sometimes tinted with red or orange, and its body is dark in color. Its wingspan is between 5.5 and 6 cm.

Adults inhabit the rainforest understory and feed on the nectar of a variety of tropical flowers. G. oto prefers to lay its eggs on plants of the tropical nightshade genus Cestrum. The silvery-gray caterpillars feed on these toxic plants and store the alkaloids in their tissues, making them distasteful to predators such as birds. They retain their toxicity in adulthood. The same alkaloids that make them poisonous also are converted into pheromones by the males, which use them to attract females.

G. oto adults also exhibit a number of interesting behaviors, such as long migrations and lekking among males.

Greta oto komt voor van Mexico tot in Panama. De vlinders leggen hun eitjes op verschillende soorten cestrumplanten. Deze behoren tot de familie van de Solanaceae. Een vrouwtje legt telkens een eitje en zoekt dan een volgende waardplant. Ze komt soms telkens bij dezelfde plant terug, zodat er meestal heel wat eitjes op een plant zitten. De bleke rupsjes hebben geen stekels. Greta oto is een zeer algemene glasvleugelvlinder, die zich in een groot aantal verschillende biotopen thuis voelt. Hij is het hele jaar als vlinder te zien; in het ene seizoen in zeer grote aantallen, in het andere met slechts enkele individuen. De vlinder kan in korte tijd grote afstanden afleggen. Van een Greta oto is in Costa Rica vastgesteld dat het vlindertje in een etmaal ruim 40 kilometer had afgelegd. Gemiddeld trekken de vlinders ongeveer 12 kilometer per dag. Zij kunnen dat redelijk veilig doen, omdat ze in de felle zon vrijwel onzichtbaar zijn als ze vliegen.

Hello Thijs,
Wonderful macro shot.I liked dark mood,framing and visual impact a lot.

Hi Thijs,
Thanks for everything and the dedication! This picture has come out really very well. The darker setting actually indicates the kind of environment that these cute little butterflies like.The lighting and sharpness are excellent! the POV is much better than what i have shot and posted! Excellent work my friend.

Muy buenas Thijs
Impresionante captura de esta mariposa, que aún con ese fondo oscuro destaca, buena nitidez y detalle.
Un saludo

Une parfaite composition, une prise de très grande qualité.


Grand picture. The lighting is brilliant. The leaf at the bottom provides an artistic touch.

The idea of composing a leaf, in the Bg clearely shows the charecter- transparency of glass wings. picture perfect, and is a nice picture to dedicate to afriend like goutham. good one.

You would think that the leafe in the background would take away from the butterfly but it doesn't. Since the leaf is a bit darker than the butterfly it kind of enhances it. This shot is very beautiful. Nice sharpness and great lighting.

This is a very nice one.The shapness is Brilliant.The BG and the compo is excelent.TFS

Hello Thijs,
Brilliant capture of the beautiful Glasswing against a wonderfully coloured background. Very sharp details and lovely colours. I like its pose on that thin line of leaf too! Very fine composition!
TFS and regards, Ulla
