Abstract
1. 1. Haemolymph osmotic pressure was measured in four species of woodlouse after pre-treatment in 100% R.H. followed by progressive desiccation. 2. 2. Considering sexes together it was found that Oniscus asellus cannot osmoregulate but that Porcellio scaber and Armadillidium depressum can. Ligia oceanica showed a greater osmoregulatory ability during aerial desiccation than some other “more terrestrial” species. All species except A. depressum showed considerable sexual variation in their response to desiccation even though the pre-treatment values were similar. 3. 3. Sodium levels were monitored with progressive desiccation in O. asellus and P. scaher. Contrary to expectation the former species showed greater sodium control than the latter.
