More butterflies

In April I have written about a stamp issued by Sweden and picturing a close up of a butterfly. I recently read that Swedish post is going to issue a second stamp in this series, I’ll show it to you when I get it.

But this time this is Finland post that just issued, on the 24th of August, a set of three stamps picturing those little insect, very popular among topical stamp collectors. Again, I think they chose an original approach, by picturing only the half of the animal. All the three stamps are auto-adhesive and have been issued in band of three.
Here are the stamps and some information about them. The first one pictures a purple emperor (Apatura iris). The orange ring that you see at the bottom of the wing is characteristic of an adult of this species. The blue shade of the wings indicates that this is a male (the female does not bear any blue).
The second stamp pictures a chequered blue (Scolitantides orion). I could not get any information about this one…

The third one pictures a palaneo sulphur (Colias palaneo). Once again this is a male that it pictured, as indicated by the brown borders of its wings.

Hi Eric,

I really enjoy reading your blog.The fact that you take time to find out so much about each stamp and share it with everyone.

Here is some info about the butterfly Scolitantides orion pictured on the swedish stamps....for which you cldn't find any info...(this is thanks to my son who did a project for his class !)

Scolitantides orion is a distinctive butterfly that is widespread throughout much of Eurasia, from Spain across to Japan. It is known by the common name "Chequered Blue" and several subspecies have been described across it's vast range: S. o. orion, S. o. johanseni and S. o. jezoensis. Two generations are produced each year (except in the colder, northern edges of its range) and it is on the wing from April to August. Larvae mature in one month and pupate beneath rocks. S. orion is impossible to misidentify as it has a striking chequered fringe and a very piebald underside. While the males tend to have more blue coloration than the females S. orion is very variable in color and the dorsal surface of the wings is sometimes devoid of blue (or the blue patch is greatly reduced) in both sexes. Second, summer broods are darker than spring broods. S. orion occurs in xerothermic habitats, preferring hot, rocky slopes where its host plant Sedum grows. Since it prefers hot, dry climates it is much more common in the southern part of its range. There it is often associated with vineyards because it shares the grape vine's (Vitis vinifera) taste in habitat. In fact, viticulture is an increasing threat to these butterflies as more and more growers exploit every bit of their land. On a more positive note, some vineyard owners in the Rhone Valley avoid using pesticides and ensure that there are plenty of other plant species between their rows of grapes, allowing for habitat. S. orion is protected by law in Poland and is of special concern in many other European countries. The strong regional differences in coloration from one population to the next confirm that this is a very sedentary species, vulnerable to local extinctions.

Hope it's useful !! and have a nice day.
