The present investigation was conducted to study the diversity of Carabids in Gerbera and Gladiolus crops of Jorhat, Assam during the year 2014 - 2015 and 2015 - 2016. The specimens were identified by following published keys and literature and described on the basis of observed morphological characteristics. Results found a total 8 species of carabids belonging to 4 genera viz., Clivina, Scarites, Harpalus, and Sparostes under 3 tribes- Clivinini, Scaritini and Harpalini 2 subfamily (Scaritinae and Harpalinae) from the flower crop Gerbera and Gladiolus. Among these 8 species, 3 under genera Clivina viz., C. assamensis, C. memnonia, C. lobata and 2 under Scarites and Harpalus, viz., S. indus, S. inconspicuous, H. rufipes, H. calceatus and one from Sparostes viz., Sparostes striatulus. Among all the species, S. indus, C. assamensis and S. inconspicuous were relatively more abundance with 18.75%, 16.75%, 15%, respectively. The species richness, species diversity and species evenness were comparatively more in Gladiolus (1.511, 1.73 and 0.889, respectively) than Gerbera (0.910, 1.205 and 0.869, respectively).
