OBSERVATIONS ON SEASONAL AND DIEL SURFACE-ACTIVITY OF THE AMPHISBAENIAN BLANUS-CINEREUS IN SOUTH-WESTERN SPAIN

The main activity period of Blanus cinereus occurred from March to Jul y, and a second period with lower activity was detected in autumn. Ind ividuals were mainly diurnal, but they also exhibited nocturnal activi ty in April, June and especially in July. Daily activity appeared to b e related to air and surface temperatures, while the annual variation in activity was also related to underground temperature. Recaptured in dividuals showed little mobility, frequently persisting at the same lo cation. The recapture rate between years was low.
