Lighton, Sable Systems International, personal communication. This is not to be confused with the white dorsal calcium carbonate plates formed during the pre-ecdysis stage of molting. Accessed November 29, at http: After about the 25th day in the pouch, the eggs hatch and the bodies of the young isopods are soft.

Economic Importance and Damage Back to Top A study was conducted on the effects of the detritivorous behavior consumption of dead plant material of the pillbug in the hydric hardwood forest of central Florida. Metabolic Rates The rate of CO 2 release was significantly reduced during conglobation.

In one experiment, A. Accessed November 27, at http: When molting, the posterior portion of the body sheds first and then the anterior portion sheds around three days later Capinera Academic Press, San Diego. Hassell M, Tuck JM. This period between desiccation trials proved sufficient, as only three isopods died between trials, while those that lived increased their body weight by an average of 3. Order refers to the order in which respirometry measurements were performed.

The breeding period lasts for about six months Paris and Pitelka Vulgarr from one mating incident can be stored in this manner for an entire year for use in subsequent broods, with older sperm bundles taking precedence over more recent genetic material when broods are laid.


WoRMS – World Register of Marine Species – Armadillidium vulgare (Latreille, )

Identification Some identification marks mentioned by Ferenc Vilisics in his comment on this picture: Wikimedia Commons has media xrmadillidium to Armadillidium vulgare. Further research should focus on the ability of conglobation to actually limit the flow of air passing over the pleopods and relate that to changes in the rate of water loss.

Retrieved February armadillidikm, Pillbugs are nocturnal isopods. This microbial activity increases soil quality and thereby contributes towards agricultural success.

Typical young adults are 10 mm long and 5 mm wide. Terrestrial isopods Crustacea, Isopoda, Oniscidea armadillisium successful colonizers of land that comprise over 1, species. The marsupium also differentiates during this time, and ovarian maturation occurs.

Ziegler A, Suzuki S. These families have more developed respiratory organs and better tolerate dry conditions than other isopods Edney ; Kuenen Geographic Range Armadillidium vulgarethe vulgarw pillbug, is native to the edge of the Mediterranean and has been introduced to nearly all worldwide terrestrial landmasses, with particularly dense populations in temperate climates.

Parson and Hoffmann have proposed that lower metabolic rates are a common response to environmental stress. After being freed of attached soil, individuals were weighed on an analytical balance and placed in 5 ml glass-aluminum chambers, which were then placed in armavillidium Sable Systems www.

pillbug – Armadillidium vulgare

The hatched mancas ramadillidium within the marsupium for three to four days and then emerge. Plants with damage to green leaves by Armadillidium vulgare Latreille include Picris echioides and Silybum marianum in the grasslands of California Paris When finding mates, the A.


The remaining part of the cycle is a 2 to 4 day ecdysis of intermolt, where the splitting of the old exoskeleton occurs and is shed from the body.

Sexually mature individuals can generally be distinguished by having a length greater than 0. Chemical controls include insecticide bait, dust, granular, and liquid formulations Capinera Armadillidium vulgare exhibits a behavior of curling posterior joints in towards anterior joints in a sphere-like shape.

The additional mass loss during handling would therefore tend to overestimate water loss from the conglobated animals. This species has limited abilities of sight, smell, and touch, provided through ommatidia, esthetascs and tactile setae, respectively. Alternatively, handling stress could well have induced conglobation and reduced metabolic rate anyway.

Their earthen tone coloration also provides some degree of camouflage against wood or rock substrates. Lipid melting and cuticular permeability: It is most easily found under stones and dead wood, but also amongst grass litter, within tussocks, etc.


Found on all continents except maybe Antarctica and in all biogeographic provinces; or in all the major oceans Atlantic, Indian, and Pacific. The name woodlouse is used for both pillbugs and sowbugs in Europe and refers to where these arthropods are armadillidoum, such as under logs. Our findings suggest that conglobation behavior may help to conserve water, in addition to its demonstrated role in protection from predation.
