The principal morphological features of the third instar of Aphodius rectus Motschulsky and A. erraticus Linnaeus are described. These features are the structure and chaetome of the epicranium, structure of mouthparts, and setation of the anal stemite.

Correlation between simple averages of 4 measurements of adults (separately for males and females) and 2 measurements of third-instar larvae was studied in 19 Palearctic species of dung beetle genus Aphodius Illiger. The greatest correlation (r=0.973) is found between head width of larvae (HWL) and elytra width of male beetles (EWM). The equation (HWL = 0.26 + 0.54 × EWM) can be used as an additional tool for rapid larval identification.
