The present study reports the occurrence and population fluctuation of Somotricus unifasciatus (Coleoptera: Carabidae), an exotic predatory species. The insects were collected once per week for 12 months, using traps, at the aviary of the Conjunto Agrotécnico Visconde da Graça (CAVG), in Pelotas, Rio Grande do Sul, Brazil. During the study, 1158 specimens of S. unifasciatus were captured. The highest occurrence period was in February (472), when the monthly average temperature was 24.7ºC, while the lowest occurrence periods were in July (01), April (0) and June (0). The population density of the coleopteron varied throughout the year, with the largest capture averages obtained during months with higher average temperatures (December, January, February and March).
