29. Homotrigona (Tetrigona) apicalis ( Smith, 1857) , Milkytipped Stingless Bee

Modern records of this species were from sites at or near to remnant dipterocarp forests, including Bukit Timah and Dairy Farm, and also Singapore Botanic Gardens. Like many stingless bees, it relies on large, mature trees with cavities for nesting sites. A relatively large number of observations (30) on iNaturalist (2021) suggest that conspicuous stingless bees, when present, can be effectively monitored by the public.
