		Armadillidium do roll into a ball when conditions are dry or when disturbed by any potential predator (personal observations).
		Vertebrate predators were given one Armadillidium and one Oniscus (a genus of non-rolling terrestrial isopods) and then were observed until they attacked and consumed one of the isopods.
		Armadillidium roll into a ball when disturbed, and this ability to roll-up could serve as a predator deterrent.

		Armadillidium is the only woodlouse able to roll itself (enroll) into a completely closed sphere with no appendages protruding.
		Armadillidium, is strongly arched and the flattening is not striking.
		Armadillidium the second antennae fit neatly into broad recesses on the front of the head permitting them to be folded completely out of harm's way when the animal enrolls.

	crustacean androgen: A hormone in an isopod and androgenic activity in decapods, The American Zoologist - Find Articles (Site not responding. Last check: 2007-09-17)
		Recently, the androgenic hormone from the isopod Armadillidium vulgare was purified and characterized on the basis of a morphological bioassay.
		In parallel, research on the androgenic gland in A. vulgare reached a peak at the end of the millenium, with the purification, characterization, sequencing and cloning of an androgenic gland hormone (AGH) (Okuno et al., 1997, 1999; Martin et al., 1998, 1999).
		In this paper, we summarize the recent advances in the identification of the AGH in the isopod A. vulgare and describe the most common models that could be used in the future as bioassay systems to facilitate the study of the AGH-its functions and mode of action-- in decapod crustaceans.

	Gordon's Woodlice Care Sheet
		Some species mostly of the genera Armadillidium, commonly called Pill Bugs, are capable of rolling themselves up in a ball, this is a defence against desiccation as well as against predators such as shrews which find it much harder to bite a ball than an unrolled Woodlice.
		The number of eggs produced by a female of any given species increases with an increase in the size of the female, one female Armadillidium vulgare is recorded as having had a brood of 267 young.
		Armadillidium vulgare is also attacked by Phyto melanocephala while Trachelipus rathkei is attacked by Stevenia atramentaria.

		Armadillidium vulgare (Armadillidiidae) is common near houses, especially in gardens or greenhouses.
		The isopod body is typically dorsoventrally flattened but that of some of the terrestrial oniscoids, such as Armadillidium, is strongly arched and the flattening is not striking.
		Sperm from the male gonopore at the tip of the genital papilla is transferred to the female by the gonopods.

	Types of variables
		For example, let's say I've measured variable X in a sample of 56 male and 67 female isopods (Armadillidium vulgare, commonly known as pillbugs or roly-polies), and my null hypothesis is "Male and female A.
		vulgare have the same values of variable X." If variable X is width of the head in millimeters, it's a measurement variable, and I'd analyze it with a t-test or a Model I single-classification analysis of variance (anova).
		vulgare in a sample from Newark and a sample from Baltimore, I might say that 52.3 percent of the isopods in Newark and 62.1 percent of the isopods in Baltimore are female.

		Sex reversal of female isopods, Armadillidium vulgare, has been induced by implantation of the androgenic gland (AG) into individuals after the initiation of morphological sex differentiation.
		The focus of the present study is to examine whether female gonads are reversed by the androgenic gland hormone (AGH) during the sexually undifferentiated period through postembryonic development in A. vulgare.
		AGH cannot be a sex-determining factor in female A. vulgare, as undifferentiated gonads of genetic females are not sex reversed by the hormone.
