The possibility of ageing Locusta migratoria migratorioides (R. & F.) adults developing under winter conditions in the field and laboratory was investigated. Cuticular lamellae in sectioned hind tibae were deposited on a regular daily basis but became reduced in thickness under lower temperature conditions. Using thin stained tibia sections it was found that ages could be confidently estimated for up to 30 days. Results were checked by using field reared locusts of known age.
