We report on the simultaneous trapping of two fermionic species, {sup 6}Li and {sup 40}K, and a bosonic species, {sup 87}Rb, demonstrating the first three-species magneto-optical trap ('triple MOT'). The apparatus including the atom sources and the three laser systems is described, and the single-species MOTs and the triple MOT are characterized. In triple MOT operation, typical atom numbers of 3.2x10{sup 7} for {sup 6}Li, 1.5x10{sup 7} for {sup 40}K, and 5.4x10{sup 9} for {sup 87}Rb were achieved. Trap loss due to interspecies collisions was observed. We describe our way to optimize the triple MOT and turn it into a suitable source for the goal to achieve quantum degeneracy by evaporative and sympathetic cooling.
