Dryas iulia (incorrectly spelled julia), commonly called the Julia butterfly or Julia Heliconian, is a species of butterfly (an insect). The sole representative of its genus, the Julia is native from Brazil to southern Texas and Florida, and in summer can sometimes be found as far north as eastern Nebraska. Over 15 subspecies have been described.

Its wingspan ranges from 82 to 92 mm, and it is colored orange (brighter in male specimens) with black markings; this species is somewhat unpalatable to birds and belongs to the "orange" Batesian mimic complex (Pinheiro 1996).

It feeds on the nectar of flowers including lantana and shepherd's needle (Scandix pecten-veneris), and its caterpillars form hosts in passion vines including Passiflora affinis and Passiflora lutea (the yellow passionvine) in Texas. The Julia is a fast flier and frequents clearings, paths, and margins of forests and woodlands.

The species is popular in butterfly houses because it is long-lived and active throughout the day.

De oranje passiebloemvlinder (Dryas julia, Engels: "Orange Longwing") komt algemeen voor van tropisch Zuid-Amerika en Midden-Amerika tot in het zuiden van de Verenigde Staten (zuiden van Texas en Florida). Hij behoort tot de subfamilie van de passiebloemvlinders (Heliconiinae) en is de enige soort in zijn geslacht. De vlinder heeft een spanwijdte van 7,5 - 9,5 cm. De vlinders hebben lange, smalle voorste vleugels. Mannetjes zijn feloranjebruin van kleur en hebben een een zwarte vlek op de voorste rand van de voorste vleugel. Vrouwtjes zijn valer gekleurd en missen de zwarte vlek. Aan de onderkant zijn de vlinders vaal oranjebruin van kleur met twee rode vlekken bij de vleugelbasis.

De vlinders voeden zich onder andere met nectar van Lantana camara. Waardplanten van de stekelige, lichtbruine rupsen zijn onder andere Passiflora biflora, blauwe passiebloem, Passiflora lutea en Passiflora vitifolia.

Hello,
Great light and object, very impressive shot, advised composition.
Regards, Pawel

I like this composition Thijs, with the positioning of the butterfly in this square crop. You also have a red leaf behind him providing excellent contrast between the butterfly and his background. Detail and colour on the butterfly is excellent, with great depth of field to really show off the butterflies detail.

Thanks, John

Hi Thijs,
Prachtige compositie met de vlinder aan de linkerkant, het licht dat op de vlinder schijnt en het donkere vlak daarachter.
Het geeft de foto mooie diepte.
Scherpte top
