An egg takes one and a half days to hatch into a larva, which then attaches to a host and takes one to two days to molt into a protonymph. A protonymph then molts into an adult. The whole lifeycle takes 7 to 16 days to complete. A minimum of 13 days is needed to go from egg to egg. The larva is the only stage that has three pairs of legs as opposed to four pairs.
