Biology
Rosumek (2017) assessed trophic resource use and period of activity within the ant community in a southern Brazil Atlantic forest. He found a number of Linepithema, reporting "None of these species showed statistically significant preferences, due to low number of records and use of several resources. Linepithema micans and Linepithema pulex seem to use resources more broadly than Linepithema iniquum, which might descend to the ground mostly to scavenge animal resources. The small L. pulex may have stronger carnivorous tendencies and, in fact, twice they were able to recruit a few dozens of workers and predate crickets just by themselves, a remarkable feat considering its size. Linepithema pulexwas found to mostly be a diurnal forager.
