“…Many insects show intrinsic visuomotor response, i.e., they show fixed motor behaviors in response to specific visual input. Wood ant foragers show an innate attraction to large and conspicuous objects (Buehlmann et al, 2020a; Buehlmann et al, 2020c; Graham et al, 2003; Voss, 1967), whereas foragers from other ant species with different foraging ecologies show innate attractions different to wood ants (e.g. (Collett, 2010; Heusser and Wehner, 2002)).…”

“…Conspicuous objects initiate innate behavior in many insects, including ants (fruit flies: (Gotz, 1987; Strauss and Pichler, 1998; Wehner, 1972), locusts: (Wallace, 1962), ladybirds: (Collett, 1988), mantids: (Poteser and Kral, 1995), leaf hoppers: (Brackenbury, 1996), ants: (Buehlmann et al, 2020a; Buehlmann et al, 2020c; Collett, 2010; Graham et al, 2003; Heusser and Wehner, 2002; Voss, 1967)), with many of these innate behaviors being ecologically tuned (e.g. prey detection, predator avoidance or landing site detection).…”

Wood ant foragers show an innate attraction to conspicuous visual cues. These foragers inhabit cluttered woodland habitat and feed on honeydew from aphids on trees, hence, the attraction to ‘tree-like’ objects might be an ecologically relevant behaviour that is tailored to wood ant foraging ecology. Foragers from other ant species with different foraging ecologies show innate attractions different to wood ants. What we do not know, however, is whether these innate visual responses vary with the ants’ motivational states or caste. We thus recorded the innate visual response of wood ant foragers with different motivational states, i.e. unfed or fed, as well as males that have a short life span and show no foraging activity. Our results show that ants from all three groups orient towards the visual cue, i.e. the wood ants’ innate visual attraction is not context dependent, but a hardwired behaviour seen across different motivational and ecological contexts.

Ants are expert navigators combining innate and learnt navigational strategies. Whereas we know that the ants’ feeding state segregates visual–navigational memories in ants navigating along a learnt route, it is an open question if the motivational state also affects the ants’ innate visual preferences. Wood ant foragers show an innate attraction to conspicuous visual cues. These foragers inhabit cluttered woodland habitat and feed on honeydew from aphids on trees. Hence, the attraction to ‘tree-like’ objects might be an ecologically relevant behavior that is tailored to the wood ants’ foraging ecology. Foragers from other ant species with different foraging ecologies show very different innate attractions. We investigated here the innate visual response of wood ant foragers with different motivational states, i.e., unfed or fed, as well as males that show no foraging activity. Our results show that ants from all three groups orient toward a prominent visual cue, i.e., this intrinsic visuomotor response is not context-dependent, but a hardwired behavior seen across different motivational and ecological contexts.

Ants in general are primarily olfactory animals, but many species also express visual behaviors. We analyze in 14 species, which range from purely olfactory to predominantly visually behaving ants, how the brains are equipped to control such behavior. We take the size and manifestation of the eyes as an indicator for the prevalence of vision in a given species, and we correlate it with the size of particular brain regions. Our morphometric data show that the size of the eyes generally correlates well with that of the optic lobes. The antennal lobes and the mushroom bodies have a surprisingly constant relative volume whereas, as expected, the relative size of the optic lobes varies strongly across species. Males of different species are more similar. Compared with workers, they all have large eyes, relatively larger optic lobes, smaller mushroom bodies, and similarly sized antennal lobes. The input regions of the mushroom bodies, the lip and the collar, generally correlate with the size of the optic and antennal lobe, respectively. Accordingly, the composition of the calyx reflects the importance of vision for the animal. We present data supporting the view that the mushroom bodies may participate in spatial orientation, landmark recognition, and visual information storage. J. Comp.
