english: The males are very picky about who they mate with, because they not only transfer sperm during mating, they also give the female something called a nuptial gift.
non_english: Samčekovia si veľmi vyberajú,  s kým sa budú páriť, pretože pri párení dávajú  samičke nielen svoje spermie, ale aj niečo, čo by sme mohli  nazvať svadobným darom.
