Abstract : The present study on three nymphal instars of Aegypoecus perspicuus indicated that these differ from each other not only an size, abdominal segmentation, chitinization but also in the number of setae occurring on head, thorax and abdomen. The study also supplements informations regarding the morphological features and chaetotaxy of three nymphal instars of A. perspicuus, occurring on Neophron percnopterus. The diagnostic features of three nymphal instars have also been discussed.
