Considerable studies of the univoltine, common field-cricket Gryllus campestris Linnaeus, 1758, known from sunny oligotrophic grasslands and heathlands of the western Palaearctic, were previously made, but none of them has shown the characteristics of its burrows. This paper presents a neoichnological study based on a group of G. campestris that lives in and around a pasture glade in Dajti Mountain, east of the Tirana District in Albania. It includes direct observations of the burrows in the field and their casts made by means of white Portland cement. Burrows of nymphs of G. campestris were observed to be tubular, sun-facing and have only one, funnel-like entrance, simple termination and no branches. This study is the first one showing morphological features of the burrows and the burrowing activity of the common field-cricket, being a contribution to ichnology of soils. Preservation of the burrows is possible by their filling, for instance by sand during flooding. The burrows do not fit to any existing ichnotaxa. [ABSTRACT FROM AUTHOR] |
