Mate recognition differences among allopatric populations of the scarab Canthon cyanellus cyanellus (Coleoptera: Scarabaeidae)

We analyzed mate recognition and the cooperative behavior of maleÐfemale pairs in Canthon cyanellus cyanellus LeConte (Coleoptera: Scarabaeidae), a carrion-feeding scarab, during food ball rolling among Þve populations found in tropical forest fragments on the eastern coastal plains of Mexico. Sexual recognition in this species is mostly mediated by chemical cues. Intrapopulation and maleÐfemale pairs formed with individual from populations
