The natural species area of S. curvatum extends from Central Asia to East India and Nepal. For the first time in Europe it was recorded in 1979 in Austria . Later it spread to other countries. The expansion of one of the species of mud dauber wasps – Sceliphron curvatum has been noted in Europe during the end of XX – beginning of XXI century. The phenomenon of expansion, in our generalizations, occurred in about five stages. At the second stage the wasp reached South and East of Ukraine (Crimea and Kharkiv region). The analysis of expansion dynamics of the species range indicates a gradual settling of S. curvatum in Europe, but it is limited by 53 grad of northern latitude, what can be explained by its termophility. The research on the territory of Ukraine was conducted by studying of museum collections, field trips and interviews. In entomological collections we found 11 specimens of S. curvatum from Lviv, Rivne, Ternopil, Kirovohrad, Transcarpathian regions and Crimea. The presence of insects in the Ivano-Frankivsk region indicates a verbal message. Eventually, the species appears almost throughout the territory of Ukraine, except of the most of Polissya. S. curvatum has been found already on the territory of 21 countries in Eastern and Central Europe.
