Abstract

Migration distance is an important determinant of the distribution area of animals and is an important factor influencing community structure. However, a few studies have reported the walking distance of terrestrial isopods. The walking distance of an exotic terrestrial isopod Armadillidium vulgare (Latreille, 1804) was analyzed by field and laboratory measurements. A mark-and-recapture field survey indicated that A. vulgare could walk 24 m per day and up to 51 m over 8 days. Moreover, this species walked about 50 m in one hour under experimental conditions (0.8 lux, 22°C). The walking ability of A. vulgare is similar to the migration distances of flying beetles and a grasshopper.
