Biology

Five nests of Myrmecia froggatti were dug out in dry Eucalyptus woodland in Queensland, northern Australia. Nest structure was simple; a single, vertical unbranched shaft that connected 6-12 chambers down to 80-145 cm. Colonies were monogynous and of small size; each contained one ergatoid queen, an average of 38 workers, and several brood (Ito et al. 1994).

Castes

Ergatoid queens had a sperm-filled spermatheca and between 15-18 ovarioles, whereas workers had an empty spermatheca and 4-15 ovarioles. Pronotum width and head width of workers showed isometric growth. However, allometric growth was observed between the width of the pronotum and the width of the fourth segment of the abdomen. Number of ovarioles was positively correlated with abdomen width. Thus, large sized workers have a disproportionally larger number of ovarioles than smaller sized workers, and may have a trophic function (Ito et al. 1994).
