Proportion of encounters in which insemination and spermatophore deposition occurred. Six D. aff. auriculatus (three males and three females) and ten D. conanti (SL) (six males and four females) were used. The number of inseminations is given first and the number of encounters in which spermatophores were deposited is bracketed. Parentheses enclose the number of encounters of that type (23 homospecific and 23 heterospecific trials in total).
