A large-scale evaluation of water traps for their efficiency in trapping male stingless bees was done, which involved 41 locations from 9 states and 88, 7 and 5 stingless bee colonies of Tetragonula, Lepidotrigona and Lisotrigona species respectively. We succeeded in collecting male bees in 82 colonies of Tetragonula spp., five of Lepido­trigona spp. and two of Lisotrigona spp. The male bees were trapped throughout the year with more than 10 males/colony in March, April, July, September, October and December. Males of Tetragonula, Lepidotrigona and Lisotrigona formed 0.17–14.29%, 0.54–21.53% and 12.35–14.21% of the total bees trapped per colony respectively. We conclude that a water trap is the best technique to collect male bees of all three genera (Tetragonula, Lepidotrigona and Lisotrigona) occurring in India within a brief period during any time of the year.
