| Description | Phaneroptera falcata was known to be widespread only in southern and central Moravia till the year 2000. During the last years, quick expansion to northern Moravia and Silesia (Moravian-Silesian region) has been observed. Based on the sequence of findings, consecutive spreading through Bohemia is also supposed. Phaneroptera nana was published from southern Moravia firstly in 2002 with findings from 1992 and 2001. At the present time, occurrence in nine localities is confirmed with the northernmost finding in Brno. Climatic changes associated with the current global warming trend in the last decades together with the increase of abandoned fields and meadows are probably the main reasons of the expansions. |
