ponorthus sp. from northern Israel appears to be skewed to the right, depicting a steep elevation in density in Decemper/JlWuary. Afterwards, density
declines gradually until May (Fig. 6.1). An analogue is the phenology of the
Coleoptera Dailognatha quadriocollis and Carterus calydonius in the four
different litter types of an insular ecosystem (Fig. 6.2). Right- or left-skewed
