Arctosa lutetiana (syn. Tricca lutetiana) (Simon 1876) (Lycosidae) is found in many European countries; however, the biology of the species is still unknown because it lives hidden under ground and is difficult to find. The objective of this study was to fill in basic information about the biology of this species. The specimens were obtained between 2005–2006. This species lives in primitive underground burrows that are not lined with silk. Herein we describe, for the first time, the burrows and the prey capture method of this species.
