Cryptops hortensis is a successful invasive species probably of Palearctic origin. However, recent molecular studies in Europe identified multiple similar species previously misidentified as C. hortensis. In the Nearctic Region, C. hortensis is presumably an exotic species with well-established populations in the northeastern USA. After molecular and morphological identification, C. hortensis from Ohio, USA, were identified as the same species in Europe. The molecular data supported the hypothesis that C. hortensis was introduced from Europe.
