24. Amegilla (Glossamegilla) insularis ( Smith, 1857) , Island Forest-Digger

This bee is forest-associated, with scattered specimen and image records available from forested sites such as Bukit Timah, Dairy Farm, Bukit Batok, Lower Peirce, and Upper Seletar. It is also known from Sungei Buloh Wetland Reserve. Most records involve single individuals, suggesting a low population size. This species is the only plausible local host of Thyreus abdominalis rostratus ( Friese, 1905) , classified above as EN.
