Nature, 1945
IT is well known that in insects during the process of moulting or ecdysis there is a thin plasma or moulting fluid. "When the epidermal cells separate from the old cuticle and begin to secrete the new, the space between the two cuticles is occupied by a thin plasma.

Turn alternation in woodlice (Porcellio scaber)
Animal Behaviour, 1967Abstract It was shown that response alternation frequency in woodlice became higher with the number of prior forced turns in one direction, but was unaffected by varied distance between the start and a forced turn. However, the frequency became lower with increased distance between a forced turn and a choice point, and also with detention following a

Exotic Woodlice in the British Isles
Nature, 1943I HAVE recently received from a greenhouse near York a small (2 mm. long) white woodlouse, which I identify as Trichorina thermophila (Dollfus)1, a Central American species. This, or an allied species, has previously been reported from glasshouses at Kew, Newcastle-on-Tyne, Winlaton Mill2, Glasgow3 and Belfast4.

Woodlice as material for research projects
Journal of Biological Education, 1980Abstract Woodlice are easy to obtain in large numbers, their biology is relatively simple, they are easy to culture, and the common species can usually be recognized with the naked eye: consequently they provide ideal material for student research projects.

Evaporation of Water from Woodlice
Nature, 1949THE presence of a waxy layer at or near the outer surface of the epicuticle of insects is well known, and its function in limiting the permeability of the insect integument to water has been fully demonstrated by Wigglesworth1, Beament2 and others. Yonge3 has demonstrated the effect of the epicuticle of certain Crustacea in determining permeability to ...

TEGUMENTAL GLANDS AND TERRESTRIAL LIFE IN WOODLICE
Proceedings of the Zoological Society of London, 1956SUMMARY The lobed tegumental glands would seem to play an important part in adapting woodlice to life on land, but although the problem seems a simple one, it has by no means been easy to determine their function. Evidence from comparative anatomy and physiology is unhelpful and often puzzling, and inactivating the glands seems to have no effect on ...
