Brown (1975) - A raid of Zasphinctus steinheili observed by me in Victoria, Australia (Wilson, 1958: 136) was waged against a small Stigmacros (Formicinae) species during the afternoon the Zasphinctus ran over bare soil, but took advantage of cracks in the earth where they could. The Stigmacros workers were seen' scattering and hiding on pieces of eucalypt bark and dead leaves lying on the ground, often carrying their own larvae. Their behavior recalled that of Formica fusca- or pallidefulva group species raided by F. sanguinea-group slavemakers in the Northern Hemisphere, and may imply the use of “propaganda” allomones such as those sprayed by the slavemakers to spread panic in the slave Formica colonies they are attacking (Wilson and Regnier, 1971).

Biology

Castes

A total of 20 ergatoid queens from 3 colonies were dissected mostly soon after collecting, during an egg-laying period (Buschinger et al. 1989). Sixteen females were all mated and fully fertile, having long ovarioles (when straightened out, as long as both gaster and petiole) with developing as well as mature oocytes. Presence of "yellow bodies" in most of the ovarioles indicated previous egg-laying. Colonies are thus polygynous.
