- Abstract
1. A laser-marking technique is described that may be used to rapidly mass-mark and individually code insects in the field. In this study, ground beetles were marked but the method is applicable to a wide range of organisms with a hard exoskeleton or shell. 2. In a field-scale capture–recapture study conducted in winter wheat, 8266 beetles were coded. Individuals marked in the first week of the trial and recaptured 2 months later retained their codes, which were therefore considered permanent. 3. Assemblages were dominated numerically by Pterostichus cupreus, which formed more than 98% of the total captures. Of the 8046 released P. cupreus, 2269 were recaptured. As an illustration of the use of these data, the POPAN parameterisation of the Jolly–Seber model was used to estimate a whole-field population of 17 237 individuals, equating to a density of 0.46 beetles m−2.
