Nesting Habits

The nests of H. saltator are exceptionally complex by ponerine standards (Peeters et al. 1994). In a mature colony the nest consists of a series of stacked chambers forming a nearly spherical structure, surmounted by a thick vaulted roof and separated from the surrounding soil by a hollow space. A tunnel leads down to a separate refuse chamber. Peeters & Hölldobler (1995) hypothesized that this nest design is an adaptation to survive periodic flooding. In addition, H. saltator “wallpapers” inner surfaces of its nests with discarded cocoons. This wallpaper is glued down and may help to keep the chambers dry. See Ant Nests

Queens and workers are morphologically similar (except for wings) and gamergates reproduce once the founding queen has died. In these two categories of egg-layers, the proportions of Cuticular Hydrocarbons change in a similar way with the onset of ovarian activity, while young virgin queens resemble infertile workers (Liebig et al. 2000). Thus the hydrocarbons are not related to morphological caste but to reproductive physiology.

Genetics

Harpegnathos saltator has had their entire genome sequenced.

Palomeque et al. (2015) found class II mariner elements, a form of transposable elements, in the genome of this ant.
