Specimen labels


This species was found in Hawaiʻi in 1967 and is now widespread in mesic to wet forest ecosystems across at least several islands (Huddleston and Fluker, 1968; Gillespie and Reimer, 1993; Reimer, 1994). In these ecosystems S. papuana is generally rare on vegetation distant from the ground (Krushelnycky, 2015), but has occasionally been observed foraging up to a height of at least two meters on tree trunks. More commonly, it attains high densities and is most active in the soil and leaf litter (Ogura-Yamada and Krushelnycky, 2016, unpub. data). Krushelnycky et al (2017) performed a field experiment to determine potential effects of these ants on populations of picture wing flies. Suppression of S. papuana in field plots resulted in a 2.4-fold increase, on average, in the rate of successful development from egg to adult in the Hawaiian picture-winged Drosophila fly D. crucigera. Six species of endangered picture-winged Drosophila species occur or were historically collected in the Waiʻanae Mountains of Oʻahu in the same or similar habitats represented by the field sites, and were therefore considered potentially threatened by S. papuana.
