External egg morphology of the camel tick Hyalomma dromedarii was studied. Injection of egg-laying females with 1% trypan blue resulted in incorporation of vital stain in the oviposited eggs. Daily measurements of fresh eggs revealed changes in egg length and width during embryonic development. Scanning electron microscopy showed the outermost layer of the egg to be spongy and porous containing clear pits of different sizes. An elevated longitudinal hatching ridge encircled the egg chorion. The development of cephalothorax, appendages, Malpighian tubules, and rectal sacs were monitered.
