Papilio machaon, the Old World swallowtail, is a butterfly of the family Papilionidae. The butterfly is also known as the common yellow swallowtail or simply the swallowtail. It is the type species of the genus Papilio. This widespread species is found in much of the Palearctic (it is the only swallowtail in most of Europe) and in North America. This species is named after Machaon, a figure in Greek mythology. Like all butterflies, Old World swallowtails undergo metamorphosis. Young caterpillars look like bird droppings which is a good camouflage. In the last two of the four instars they are green with black transversal bands carrying 6 rows of reddish spots. To defend themselves the larvae can protrude an orange, fleshy, smelling fork behind their heads called osmeterium.

Chamaenerion angustifolium is a perennial herbaceous flowering plant in the willowherb family Onagraceae. It is known in North America as fireweed, in some parts of Canada as great willowherb, in Britain and Ireland as rosebay willowherb. The plant is also traditionally known as Saint Anthony’s laurel. It is also known by the synonyms Chamerion angustifolium and Epilobium angustifolium. The generic name Chamaenerion means “dwarf-oleander” and the Latin specific epithet angustifolium translates as “narrow-leaved”. It is native throughout the temperate Northern Hemisphere, including large parts of the boreal forests. The common name fireweed derives from the species’ abundance as a colonizer on burnt sites after forest fires. In Russia, its leaves were traditionally used as a tea, before the introduction of tea from China starting in the 17th century, it was greatly valued and was exported in large quantities to Western Europe as Koporye tea, Russian tea or Ivan Chai. Fireweed has many uses in traditional medicine.

Aster alpinus
February 23, 2024 by Dmitry Poltavsky
Aster alpinus, the alpine aster or blue alpine daisy, is a species of flowering plant in the family Asteraceae, native to the mountains of Europe (including the Alps) and Asia. The genus Aster once contained nearly 600 species in Eurasia and North America, but after morphologic and molecular research on the genus during the 1990s, it was decided that the North American species are better treated in a series of other related genera. After this split there are roughly 180 species within the genus, all but one being confined to Eurasia. The name Aster comes from the Ancient Greek word aster meaning “star”, referring to the shape of the flower head. This herbaceous perennial has purple, pink, white or blue flowers in summer. The Latin specific epithet alpinus means alpine and from high mountains above the timber line.
