Abstract：behavior and sexual selection behavior of females of three bushcrichets, Gampsocleis gratiosa, G. sedakovii obscura and Uvarovites inflatus were studied with “Y” puzzle trials. The results showed that the mating behavioral patterns of three species were roughly same, but the temporal distribution of mating was different. Females preferred to larger males. The spermatophore weight was complicatedly correlated to male body weight, in which the cubic function was best fitted with highest value of R2. Percentages of spermatophore in body weight were all more than 10.0%, i.e. G. gratiosa 11.1%, G. sedakovii obscura 125% and U. inflatus 14.9%.
