Deroceras laeve, Filicaulis bleekeri and Meghimatium bilineatum are members of Gastropoda (Mollusca) that live as pest. However they are potential for protein source of animal livestock. Mating behavior and reproductive cycle of those were inspected for 42 days. The mating phase of F. bleekeri and M. bilineatum started from touching each other with tentacle or touching another slug’s body or tail with tentacle, slug come closer to other which will be the partner, stuck each other position, and withdrawal. The mating phase of D. laeve investigated slug touched body or tail another slug with tentacle. Mating behavior of M. bilineatum and F.bleekeri which stick each other position was the longest mating duration (average 281,4 second and 561,9 second respectly) during 42 days observation. D. laeve produced 264 eggs, took average incubation period for 14 days and had hatching percentage 60.98%. The fecundity per individual is 0.31/day.
