Though larger males usually produce heavier spermatophores, neither spermatophore weight nor male body weight influence the number of eggs laid or the percentage of eggs hatched. The spermatophore transferred at mating does not constitute as paternal investment, as spermatophore weight has little effect on female reproductive output. In fact, Edith's checkerspot females emerge from eclosion with all oocytes present and a portion already yolked, further limiting the role of the male spermatophore. Most male reproductive effort is devoted not to the production of a spermatophore, but to the acquisition of females, especially virgin females. Males often exhibit indiscriminate mate location behavior, which is characterized by males failing to distinguish between female conspecifics and other objects, frequently resulting in misdirected courtship or attempted copulation. Because the cost of mistakes is low (low investment in spermatophores) and potential reward (location of receptive female) is high, indiscriminate behavior can become advantageous. However, in some cases, males become attracted to spider webs containing dead conspecifics, mistaking the motionless bodies in the webs for teneral females, and attempt copulation. This puts them at risk of death, showing that there is a risk of male mortality associated with indiscriminate mate location behavior. However, the benefit outweighs the cost, and indiscriminate mate location behavior prevails.

Edith's checkerspot males sometimes form aggregations on patches of bare ground like ridges or peaks, and from these perches they dart after passing males and females of both their conspecifics, own species and heterospecifics, other species.
