28. Megachile (Callomegachile s.l.) tuberculata Smith, 1857 , Tuberculate Resin Bee

This large-bodied species is known from a limited number of records from forest sites such as Bukit Timah, Dairy Farm, and Nee Soon Swamp Forest ( Ascher et al., 2016b), but has recently been found in a community garden outside but near to forest ( Soh et al., 2017) and at HortPark, a semi-urban park near secondary forest, in 2020. Thus, the large-sized M. tuberculata is evidently able to disperse to floral resources located a considerable distance from forest sites.
