Linepithema angulatum

Linepithema angulatum is considered a generalist ant (Calle et al. 2013) that usually inhabits anthropogenic modified ecosystems. It was collected in pine, bean, coffee, and peach crops, mature forest fragments, and home gardens. Interactions with other organisms are recorded from specimens labels, for example, attending aphids, and membracids; commensalism interactions with other insect families such as Curculionidae, Cercopidae, Forficulidae and Dryinidae have been also reported (Mera et al. 2010). Some records showed L. angulatum nesting in Cecropia sp.; this plant, native to the Neotropics, is usually associated with ants of the genus Azteca Forel (Longino 1991). (Escarraga & Guerrero, 2016)
