| Popis: | We used time-lapse cameras, in combination with dataloggers for microclimate (air humidity and temperature), in an insect field study to analyse behaviour of caterpillars over several larval stages and determine mortality reasons in relation to microclimate. We studied caterpillars of instar 1–3 of the Moorland Clouded Yellow (Colias palaeno, Linnaeus, 1761), that is from hatching from the egg until hibernation. The observation by time-lapse cameras enabled us to gather data on several caterpillars simultaneously over longer time periods. Especially, the combination with dataloggers collecting microclimatic data gives interesting insights in the life, mortality causes and behaviour of the observed caterpillars in relation to microclimatic conditions. To our knowledge, time-lapse or automatic cameras combined with dataloggers collecting microclimatic data have not been used in field studies on phytophagous insects, but only in defined experimental settings or to observe pollinators visiting flowers. Therefore, we summarize our experiences on opportunities and limitations in this communication. If the observed insect is not moving too far and is most of the time visible on the upper surface of the leaf this method can be used for several research questions under very different conditions. |
