Pieris rapae #1 - Small White
|[Note Guidelines] Photographer's Note|
|Pieris rapae from Fleeting Memories From Summer -06, seen savouring Rubus caesius "Dewberry".|
It's a pain at times to differentiate between the Small White and its cognate the Large W. when seen flittering around. The Small W. (wings 40-56 mm) is about 10 mm smaller than the Large W. (wingspan 50-64 mm) but they are both fairly similar in appearance and habits, and sizes may overlap. In the P. rapae the greyish-black tip of the upperside of the forewing ends in a straight line against the wing, while curving inwards in the P. brassicae, and not going as far down along both margins of the wing as in the latter. The female, besides having more saturated colours and fuller lines, is also marked with two clear black spots on the uppersides of the forewings, while the male, being paler, only has a diffuse spot in the middle of the upperside of each forewing. The undersides of the forewings are marked with two distinct spots in both sexes.
This species can move 100-200 km away from its original home during its life-time, a real migrater and colonizer but also noxious invader at times, its larvae doing great harm to vegetables. The larvae of the Small W. don't store the mustard oils from their foodplants like the Large W. do and so are not as distasteful to predators like birds - this fact curbs their ravages somewhat. In Sweden it flies in two generations: May-June and July-mid Sept; with a third generation in southern Sweden until Oct. The P. rapae hibernates as a pupa.
World distribution: Due to man's carelessness it has become a true cosmopolitan, found all over the world! Host plants are Brassicaceae spp. “Crucifers”.
Genus: Pieris, pierís πιερίς (Lat. "Píeris") synonym for the more common Greek word mousa (μοῦσα) "muse") and derived from the place name Piería (πιερία) (of unknown origin), one of the most ancient cult places of the muses situated in the vicinity of the Olympic mountain.
Species: rapae, genitive of Latin rapa in Brassica rapa ("Turnip") which is one of its host plants.
Swedish: "Rovfjäril" thus comes from "rova" ("turnip"), not "rov" ("prey") as people sometimes think because of its voracious raids.
For names in most European vernaculars, distribution maps, etc., the interested student is recommended Chris Jonko's (Christopher_PL on TN) great site European Butterflies.
Swedish: "Rovefjäril" should read "Rovfjäril"

A good composition and beautiful colours for this presentation of Pieris rapae. Thank's a lot for the interesting note and the ethomology of the name.

Excellent picture with wonderful sharpness and details. I like very much colors and blurred bg.
My compliments and TFS.
The butterfly is well captured, so I wouldn't make fuss about the OE leaves of its perch.
The POV is good and details on the wings very fine.
pretty and lively image of that seemingly happy muse - thanks for so well explaining the ethymology of "Pieris".
The picture is well composed, and well detailed.
Some overexposed parts on the plant in the foreground might be treated in postwork, and the picture is fine.
The steeply bent proboscis of that lovely Rovfjäril muse looks quite amusing.
With thanks, and best regards,
Magnifica imagen,muy buena toma y buena composicion.Bonitos colores y buena luz.Saludos.
