Duration of ontogenic development of Pseudacarapis indoapis Lindquist, a tarsonemid mite associated with the Indian honeybee Apis cerana Fabr. ranged from 154 to 187 hours for males and 206 to 218 hours for females. Development involved a single larval period in between egg and adult stages. Marked sexual dimorphism has been recorded among the larvae during late larval period. Breeding activities involved guarding of female by male followed by retroconjugation. Sex ratio among the progeny of fertilised females varied between 1.41:1 and 2.75:1. Unfertilised females produced only male progeny.
