Not sure what accounts for the sudden appearance of large numbers. Perhaps it has something to do with the lack of rain over the past few years and they all just hunkered down until now. Outbreaks of Calosoma certainly get most of the attention here in North America. Here in the East, C. wilcoxi had one banner year that just happened to coincide with an explosion of fall cankerworms. Several species of Stenolophus can reach pretty high population numbers around here in the spring, too, but they are simply small and annoying as opposed to conspicuous and stinky!! Other carabid species are known to have similar population explosions occur in the genera Amara and Tanystoma.Margarethe Brummermannhttps://www.blogger.com/profile/05623937180200255796noreply@blogger.com
