The article casts light upon the contemporary condition of the flora of the “Zmeyova dupka” Natural landmark, Stara Zagora Region, South Bulgaria. Significant floristic diversity is registered on an area of 40 hectares - 129 species of higher plants (mosses excluded), belonging to 101 genera and 40 families. Investigation is conducted in the 2006 ? 2008 time span and up to date in 2012. Taxonomic structure, ecological and biological type, and the floristic belonging of the components of the flora are analyzed. 4 Balkan endemics and 2 species with Nature preservation status according to the Bulgarian and international legislation are found. According to the existing legislation the territory protects object of the inanimate nature (rocky cave), but the established endemic, tertiary relicts, rare, and medicinal plants require introduction of plant preservation measures.

The influence of distinction of forage on a physiological condition of specimens of the Apsheron population of the American white butterfly is studied for the first time. It was proved that the beginning and duration of the pupate process doesn’t depend on the systematic position of a fodder plant on which the American white butterfly caterpillars develop. The physiological condition, i.e. metabolism level depends on the forage composition. In the physiological context, the 2nd generation pupae are much stronger than the 1st and if conditions allow to be formed, even the 3rd generation. It is established that depression level in the American white butterfly population dynamics is defined by the physiological condition of wintering pupae, in particular the quantity of reserve substances in a adipose body.
