Descriptions and morphometrics of the eggs and waxen structures on the nymphs and adults of Orthezia insignis are given. Architecturally, the waxen designs are similar throughout the nymphal instars but vary in the construction details. On the newly hatched (issued) nymphs only structural outlines are visible under a binocular microscope and on older instars, wax secretions become progressively more copious and conspicuous. At adult stage, the greatest amount of wax is used to construct the ovisacs. Reproduction was parthenogenetic and embryogenesis was characterized by three colour changes of the eggs: the white, newly laid eggs successively turn light yellow; bright yellow and then brown before eclosion. The frequency of nymphal issuance was influenced by the relative positions of the egg batches inside the sac. Nymphs hatching from eggs laid late in life, took longer to scramble out of the sac. Evidence deduced from the rate of nymphal issuance and the mean number of light yellow eggs at any given time, suggested that ovulation, embryogenesis and eclosion are probably synchronized biological activities in Orthezia.
Development of nymphs in the laboratory took approx. 42 days and was marked by three stadial stages. Morphometrics of the right metathoracic femurs from dead nymphs and exuviae reliably confirmed a similar developmental pattern in wild population.
