Nylanderia fulva, also known as the Rasberry Ant or Crazy Tawny Ant is an emerging pest species in the Southern United States. It is a small, dull brown ant with abundant long acuminate hairs and plentiful pubescence. Morphologically, the worker caste is indistinguishable from N. pubens. The species was referred to as Nylanderia cf. pubens until molecular work determined its true identity. For a recent study of this species, see Gotzek et al. (2012).
