 A laboratory test showed how males of P. labiata minimise the risk of meeting each other , by recognising fresh pieces with blotting paper , some containing their own silk draglines and some containing another male 's . Males also were attracted by fresh blotting paper containing females ' draglines , while females do not response to fresh blotting paper containing males ' draglines . This suggested that the males usually search for females , rather than vice versa . Neither sex responded to one week @-@ old blotting paper , irrespective of whether it contained males ' or females ' draglines . A similar series of tests showed that P. fimbriata from Queensland showed the same patterns of responses between the sexes .
