Abstract

1. Catches in traps at 12 and 200 m above ground, and observations with entomological radar, were used to document the high-altitude windborne movements of carabid beetles over agricultural land in south-east U.K. during July 1999, 2000, 2002, and 2004. 2. Notiophilus biguttatus (Fabricius) was found to be the most abundant species at altitude, with flights by reproductively immature adults resulting in millions of beetles passing through a 1 km(2) window during the brief migration period in July 2002. 3. This result was unexpected in view of the conclusions of an earlier, classic Dutch study by den Boer and colleagues that classified N. biguttatus as a poorly dispersing species that tended to become isolated in remnants of natural habitat. 4. Reasons for the discrepancy between the two studies are discussed. It is hypothesised that the high mobility seen in the N. biguttatus populations results from a recent adaptation of the beetle's migration syndrome allowing it to exploit the mosaic of temporary habitat patches making up the increasingly intensive agroecosystems of northern Europe.
