    Life Cycle:

    Direct development with rabbits as the definitve host. No intermediate host required.

    Egg development rate is temperature dependent; the ost rapid development of eggs was at 35 C at which 73% of eggs had motile juveniles in 4 days. At 20C, 9 days were required for development of motile larvae  (Yevstafieva et al., 2022).
