The eggs are relatively large, and within around 2 days transform into a hexapod larva. The larvae then moult into a protonymph , which then subsequently moults into a tritonymph. Finally the tritonymph moults to become a mature adult.
The eggs are relatively large, and within around 2 days transform into a '''hexapod larva'''. The larvae then moult into a '''protonymph''', which then subsequently moults into a '''tritonymph'''. Finally the tritonymph moults to become a mature adult.
Each stage takes around 2 days to complete. The total duration from egg to adult, takes around 10 days, but this figure can longer.
