A synthesis of research that has been conducted on resorption in the o
vary in Scarabaeinae is provided. In the Scarabaeinae, resorption in t
he ovarioles is correlated with the complexity and efficiency of nesti
ng behavior. The phenomenon can occur in different ways and to differe
nt degrees, depending on physiological, behavioral and ecological cond
itions. Studies done to date (including cases with and without parenta
l care of progeny) are reviewed. Resorption in the ovary is correlated
with rate of oviposition, existence of suboptimal conditions, age of
the female and degree of parental care. A table of the taxa discussed
is provided.
