Just as raising indra swallowtail caterpillars can be inherently complicated--click here for more information--so is setting up a female cage.  Because females in nature tend to lay eggs on healthy plants that can support the larva through to pupation, and because these healthy plants generally are situated between rocks, it is helpful to set up your cage with hostplant Lomatium and Cympopterus between rocks. 

This particular cage setup was built especially for Papilio indra.  It has a separate wooden base where the water bottle neck is flush with the top of the water bottle; giving the female more room to lay eggs.
