Here many forumchane from neighboring areas (not only Moscow) complain that mourning has become rare. And in the Yaroslavl region, although there are fluctuations in the number over the years,it is impossible to attribute it to rarities. It occurs consistently and regularly. At the same time, it is worth considering that I don't pay much attention to butterflies, more and more to beetles. Another question is that in the late 60s and early 70s, it was constantly visible even in populated areas, and now I find it more often in the woods. But in numbers certainly not less than the swallowtail, for example. And about its ordinariness on the forum already so many copies are broken, including when discussing Red Books.

We need pupae of Urticaria, Polychromatica, Mourner, Uglokr. V-white.
Next year I plan to reintroduce 250 polyxene(pupae) and 100 euphorbia hawkmoth(pupae)in our reserve.
Can someone otzavetsya, you can exchange.

I don't know about polyxena, but with other species - in my opinion, a hopeless occupation. Imagos fly well and are present in neighboring regions. If the conditions were right, they would have bred themselves long ago. In the 80s, urticaria on the mainland of Ukraine was a mass species, and now it is very rare.
In Crimea, urticaria occurs exclusively along the main ridge of the Crimean Mountains. Although there are enough nettles in other places, including in the adjacent territory, where there is even more of it (nettles). But she (urticaria) does not want to "introduce" there - and that's it!

I can add that until 2003, mourning grounds were full on the outskirts of Moscow, especially in the early spring. In the same year, I saw a total of four times in the Ministry of Defense, in the Sergiev-Pasadsky, Orekhovo-Zuevsky and Lukhovitsky districts. But in mid-August, in the Tver region, near the border with Vologda, they flew in droves. But polychrome last 6 years have not seen in the MO at all...

I am not a "butterfly man", so I would like to clarify: what kind of polychrome are we talking about-Nymphalis xanthomelas or N. polychloros? According to my observations, polychrome simply lead a more secretive lifestyle compared to mourning, for example. In the early spring, after wintering, they laid eggs and went to another world, and the second generation has a very short period of active summer before hiding "in the cracks" for wintering. So they don't come across very often. And for an inexperienced observer, they are generally not very catchy and recognizable.
