Schwarziana quadripunctata is a small, stingless bee found in a stretch of the South American Amazon[dubious – discuss] from Goiás, Brazil, through Paraguay, to Misiones, Argentina.[1] This highly eusocial insect constructs earthen nests in the subterranean level of the subtropical environment, an unusual feature among other stingless bees. The species ranges in sizes from 6.0 to 7.5 millimetres (1⁄4 to 9⁄32 in) and feeds on a diverse diet of flowering plants found abundantly on the forest floor, including guacatonga (Casearia sylvestris) and the mistletoe species Struthanthus concinnus.[2]
