Besides the rare eye witness accounts in the wild, most breeding information about P. vitticeps is from captive keeping. The first time it was ever recorded in the wild however was by Worrel in 1970. Having deposited the clutch, the lizard emerges from it and covers the hole. P. vitticeps becomes sexually mature between one and two years of age. The Prime breeding age for females is one to three years of age, however males on the other hand do not decrease breeding capabilities as they age.
Clutches vary with the individual female, however fifteen to twenty-five is typical in one clutch.
The record for most eggs in a clutch is sixty-four. Incubation for bearded dragons in captivity ranges from two to two and a half months, however it might go longer in the wild due to longer times at lower temperatures. Hatchling P. vitticeps have a weight of .13 ounces, and a snout to vent length of 1.7 inches. A month after their birth, the juveniles are usually about five inches in total body length. Juveniles will grow quite rapidly reaching adult size within a year if an optimum diet is provided.
