Provide artificial nest sites for solitary bees Bee Conservation

Klein et al. (2006) found 25 species of natural enemy attacking 14 bee and wasp species nesting in nest boxes in shade coffee and cacao plantations in central Sulawesi, Indonesia. 2.1% of bee brood cells were attacked in this study, although no predators or parasitoids were recorded for the most commonly found bee, the megachilid Heriades fulvescens, which made up 20% of all brood cells.
