Summary[edit]
| Description |
English: Carabus nemoralis Müller. This European species was first discovered on this continent in New Brunswick around 1890 and was recovered on the west side of Lake Ontario in 1919 and in southeastern Wisconsin by 1934. Unless the species went undetected for a long period of time, these dates would suggest that the species spread westwards for an average of 38 km per year. This is highly improbable for a wingless species and therefore its spread on this continent was undoubtedly enhanced by human transport unless separate introductions occurred. |
