As soon as a ferapetus egg hatches the new born will immediately go in search of a host in which it'll gestate for about an hour or so. After finding a suitable host the ferapetus secretes an enzyme inhibitor that'll sedate the host until it's fully grown.

However, the enzyme inhibitor that a ferapetus secretes will slow down the hosts photo receptors in the eyes.
