1) At HortPark, a female Euaspis polynesia was observed entering multiple nests built by Megachile fulvipennis and transferring resinous material from one nest to another. The Euaspis had likely bored into the nests and was now reconstructing the cell partitions after removing the host egg, and laying her own egg within it. These nests were made in a bee hotel comprising wood blocks with drilled holes and situated along the HortPark’s Bee Trail (NParks, 2020). 2. At Tampines Street 22, a female Euaspis polynesia was observed chewing through the resinous plug of a nest made by a Megachile fulvipennis and subsequently entering the nest. The host bee returned subsequently, and was observed re-building this nest. After about one and a half months, three adult Euaspis polynesia were observed emerging from the nest cell. At a separate nest, a host Megachile fulvipennis was observed attempting to fend off an invading Euaspis polynesia, (see video at https://youtu.be/SJlykYx-3P0). These nests were made in a bee hotel located beside a community garden, and comprised of hollow bamboo internodes. 3) At Elias Road, a female Euaspis polynesia was observed chewing nest plugs and entering multiple nests made byMegachile disjuncta. The nests were made in drill holes of a shelf located in a balcony of a residential apartment on the 8th floor.

The house wolf snake is a common reptile in suburban and rural habitats in Singapore, and feeds mainly on geckos (Baker & Lim, 2012: 104). As shown in the attached photographs (Figs. 1-5), the prey is seized by the head and held in the snake’s coils until it is subdued (Lim & Lee, 1989: 54). It appears that the snake constricts its prey to prevent it from escaping, and does not seem to suffocate it like a python does.
