X. nasalis is a common carpenter bee found in Southeast Asia, predominantly in tropic and subtropic regions such as Thailand, Vietnam, West Malaysia, and Singapore.
Nest Nests of Xylocopa nasalis are strictly unbranched and the provisioned cells are separated by distinct partitions made from bamboo shreds excavated by the founding female. Usually, the nest entrances are located mainly at the end of the bamboo culms, but there can be excavation from the underside for an entrance.
The average total nest length is 38.35 cm and the average nest length (from the nest entrance to the end of the innermost partitioned cell) is about 25.40 cm. The number of cells partitioned per nest is between zero and eight cells, with an average of about three per nest.
Nest population On average, there can be anywhere from 1 to 7 individual adult bees in an X. nasalis nest, with a female-biased sex-ratio of 8:1. In a given nest, sister bees can tolerate and live inside the same nest with up to 7 individuals along with their mother.
