Pieris napi from Fleeting Memories From Summer -06 on Cirsium arvense, "Creeping Thistle".

An interesting fact about this species is that it is one of few diurnal species that is not dependent on direct sunlight but flies even in cloudy (but warm) weather. In all stages of its development it is repellent to birds and is therefore not dependent on sun heat to enable a faster flight away from its predators!

World distribution: All areas within the tempered zones of Europe, Asia (including the Indian subcontinent), North America, North Africa (only in the Atlas Mountains).

Taxonomy:
Family: Pieridae with 4 genera in the Nordic countries: 1. Anthocharis, 2. Aporia, 3. Pieris, 4. Pontia.

Genus: Pieris with 3 species in the Nordic countries: 1. P. brassicae, 2. P. napi, 3. P. rapae.

Species:
1. P. brassicae, ("Large White") often seen in gardens and parks like its noxious relative P. rapae ("Small White" or "Cabbage White" in Am. Eng.), whose larvae obtain protection from predators by storing distasteful mustard oils from their host plants. The parasitic wasp Apanteles glomeratus helps to reduce its devastating progress somewhat however. Unfortunately I can't present a decent shot of this species for the time being, but fortunately I can present one of the most beautiful specimens I've seen of it anywhere around, namely fiyo's_P. brassicae!
2. P. napi, ("Green-veined White" or "Sharp-veined White" in Am. Eng.) does not visit gardens and parks as often as its two relatives P. brassicae and P. rapae. Unlike them, it prefers wild crucifers as host plants - especially Cardamine pratensis ("Cuckooflower") and Allaria petiolata ("Garlic Mustard"/"Hedge Garlic") - and is thus seldom a garden nuisance.
3. P. rapae, ("Small White" or "Cabbage White" in Am. Eng.), is, along with P. brassicae ("Large White"), often encountered in vegetable gardens and parks. The larvae of the "Small White" don't store the mustard oils from their foodplants as those of the "Large White" do and so are not as distasteful to predators like birds - this fact curbs their raids somewhat. For illustrations, please see my P.rapae-postings.

For names in most European vernaculars, distribution maps, etc., the interested student is recommended European Butterflies.

Hello Goran,

I like the softness of this picture, great capture of this butterfly, high quality image, and pleasant for looking.

Bonjour Goran,
Une nouvelle photo magnifique de ce papillon. Elles est peu moins lumineuse que la précédente, mais elle met mieux en valeur les écailles grises qui soulignent les nervures des ailes. Très réussi.
Salutations

Hello Goran,
You seem to have a whole collection of butterflies. This shot of Pieris napi is excellent and we find again the thistle-flower, which I could observe in my country too, is very attractive for insects.
Bonne journée
Anne
