Abstract Cholesterol and its esters appear to be the only steroid materials present in the tissue lipids of adult female cattle ticks and their eggs. The total cholesterol content of newly dropped engorged females weighing between 100 and 300 mg ranges from 300 to 700 μg per tick and shows a direct relationship with engorged weight. Females of similar weight which have completed oviposition contain 10 to 18% of the cholesterol originally present. Eggs contain a virtually constant amount, 1500 μg per gram of egg weight. A balance sheet constructed from these figures accounts for only 37 to 51% of the cholesterol present in the engorged tick. Substances giving reactions typical of steroids are present in egg wax and the cuticle wax of ovipositing females, and the possibility that they are derived from the missing sterol is discussed.
