The three-dimensional structure of the tracheal tapetum lucidum, its reflection properties and the resulting eye glow hue were studied in members of the diurnal butterfly families Pieridae, Nymphalidae, Satyridae and Lycaenidae. Two main groups of tapeta can be distinguished by structural and physiological differences. Whereas in pierids the main tracheal trunk at the bottom of the rhabdom bifu...
Oxygen convective uptakes in gas exchange cycles were directly recorded in early diapause pupae of Pieris brassicae L. (Lepidoptera; Pieridae) by means of O2 coulometric respirometry. This method was combined with flow-through CO2 respirometry, the two systems being switchable one to the other. During recording with both systems, measurements were also taken with infrared actography. The pupae ...
Little is known about the single reported population of Dirca mexicana. I monitored air temperature from mid-2005 through mid-2007, analyzed pH of soil, used the global positioning system (GPS) to define geographical boundaries of the population, explored for additional populations, and studied aspects of sexual and asexual reproduction in situ and among seedlings in greenhouses. Temperature ra...
