 The majority of limia species rely on forced copulation, in which the male thrusts his gonopodium into the female's genital pore without a prior display.The consequence of this system of mating can be the undermining of female choice, halting the progression of sexual selection on male traits and in some cases inhibiting speciation.Fertile hybrids have been obtained between "L. melanogaster" and both "L. nigrofasciata" and "L. vittata".
