A. fraterculus has a lek mating system. Males of A. fraterculus emit a sexual pheromone to attract females. Females choose with whom to mate exerting sexual selection. Pheromone composition is variable among morphotypes of this cryptic species. The A. sp. 1 aff. fraterculus morphotype has at least 30 compounds. Females displayed strong electroantennographic (EAG) responses to five of them. The objective of this work was to test if some of these compounds (presented alone or in a blend) elicit a behavioral response in A. fraterculus females.
