Abstract. Here we report on the nocturnal bull ant Myrmecia pyriformis, a species whose activity to and from the nest is mainly restricted to the dawn and dusk twilight respectively. Recent research on M. pyriformis has focussed on its visual system, the timing of activity patterns, and the navigational strategies employed by individuals while foraging. There is, however, a lack of basic ecological information about this species. The present study describes the behaviour and foraging ecology… 

The View from the Trees: Nocturnal Bull Ants, Myrmecia midas, Use the Surrounding Panorama While Descending from Trees

It is shown that views acquired at the base of the foraging tree nest can provide reliable nest-ward orientation up to 1.75 m above the ground, and how animals descending from trees compare their current scene to a memorised scene is discussed and the similarities in visually guided behaviour while navigating on the ground and descend from trees are reported.

Polarized light use in the nocturnal bull ant, Myrmecia midas

The use of polarized light during outbound and inbound journeys and with different home vectors in the nocturnal bull ant, Myrmecia midas, is explored and why weighting on polarization cues change in different contexts is discussed.

Compass cues used by a nocturnal bull ant, Myrmecia midas

The nocturnal bull ant, Myrmecia midas, uses multiple cues to navigate and appears to rely heavily on landmark information for navigation.

Evidence for the Absence of Worker Behavioral Subcastes in the Sociobiologically Primitive Australian Ant Nothomyrmecia macrops Clark (Hymenoptera: Formicidae: Myrmeciinae)

Activity in three colonies of the nocturnally foraging Australian ant Nothomyrmecia macrops is investigated, and Behavioral subcastes comprising “domestic” versus “foraging” workers were not indicated, evidencing absence of worker caste polyethism in N. macrops.

Light and dark adaptation mechanisms in the compound eyes of Myrmecia ants that occupy discrete temporal niches

The histological techniques used to study the light and dark adaptation mechanisms in the compound eyes of diurnal, crepuscular and nocturnal Myrmecia ants found that, except in the day-active species, all ants have a variable primary pigment cell pupil that constricts the crystalline cone in bright light to control for light flux.

Colony structure, population structure, and sharing of foraging trees in the ant Myrmecia nigriceps (Hymenoptera: Formicidae)

A significant correlation between tree sharing and geographical distance between nests is revealed and the colony structure of M. nigriceps is investigated, which is found to be monodomous and to have no correlation between internest relatedness and tree sharing.

Microhabitat Characteristics of Myopopone Castanea (Hymenoptera: Formicidae) in Oil Palm Plantation

The results showed that the colonies of M. castanea in both of plantations vary greatly in the size of the number and stage of the ant development stage, which indicates that a suitable abiotic environment will support life and mass rearing of the M.Castanea ant colonies.

Subtle changes in the landmark panorama disrupt visual navigation in a nocturnal bull ant

It is found that immediately after the trees were removed, ants walked slower and were less directed, their foraging success decreased and they looked around more, including turning back to look towards the nest.

Different effects of temperature on foraging activity schedules in sympatric Myrmecia ants

It is concluded that temperature determines the timing of foraging as well as the daily and seasonal foraging activity in M. croslandi, but has less obvious effects on M. pyriformis.

Navigational Efficiency of Nocturnal Myrmecia Ants Suffers at Low Light Levels

Investigation of the navigational efficiency of a nocturnal ant, Myrmecia pyriformis, at different light levels found that in both bright and dark conditions ants relied predominantly on visual landmark information for navigation and that landmark guidance became less reliable at low light conditions.

Notes on the field behaviour of two ant speciesMyrmecia desertorum Wheeler andMyrmecia dispar (Clark) (Hymenoptera: Formicidæ)

Field observations on orientation suggest that the workers memorize the position of trees on which to forage and that visual stimuli are important for capturing prey.

Nocturnal orientation in the black carpenter antCamponotus pennsylvanicus (DeGeer) (Hymenoptera: Formicidae)

The black carpenter ant, a predominantly nocturnal Formicine ant, responds to a hierarchy of visual and tactile cues when orienting along odor trails at night, and the hierachical organization of these diverse cues in a foraging strategy is discussed.

SummaryThe queen makes a very simple nest structure which appears to be a common design for mostMyrmecia species. However, after the appearance of the first workers the nest structure changes slowly

Notes on female and worker survivorship in the archaic ant genus myrmecia

The evidence seems good that, even at the primitive grade of social development of the archaic ant genusMyrmecia, survivorship capacities of fertilized brood females are comparable with those of many higher ants.

The twilight zone: ambient light levels trigger activity in primitive ants

It is suggested that the reason for restricting the foraging onset to twilight and measuring light intensity to trigger activity is to optimize the trade-off between predation risk and ease of navigation.

Comparative data on phylogenetically "primitive" ants can help understand the selective forces promoting the production of multiple worker castes as well as the morphological divergence between queens and workers in Myrmecia gulosa.

Note on the exchange of ingluvial food in the genusMyrmecia

The last worker extended the general theory of the exchange of ingluvial nutriment to other social insects, called it oecotrophobiosis, and predicted that it would be found of great importance in maintaining colonial solidarity among the social insects in general.

Gamergates in the Australian ant subfamily Myrmeciinae

The first occurrence of gamergates (i.e. mated reproductive workers) in a myrmeciomorph subfamily is reported, in a colony of Myrmecia pyriformis that was collected without a queen and indicated that three workers were mated and produced the diploid offspring.
