Taxonomic History (provided by Barry Bolton, 2014)

Formica prociliata Kennedy & Dennis, 1937 PDF: 531, figs. 1-9 (w.q.m.) U.S.A. Nearctic. AntCat AntWiki




Habitat: Well-drained brushy prairie and open oak savanna. Originally reported from an oak woodland with a carpet of so-called bluegrass, I suspect the groundlayer may in fact have been the common oak-savanna sedge Carex pennsylvanica, as this ant is not likely to be a species of the sort of disturbed areas where lawn grasses would dominate.

Natural History: Long trails of F. prociliata workers interconnected several different, well-populated, thatched mounds at the Lamoni, Iowa site where I found this ant, a couple of miles north of the Missouri line. The mounds had twiggy thatch, and were similar in appearance to mounds of F. obscuripes. When disturbed, workers were quite aggressive, swarming over my hands and spraying quantities of pungent formic acid. Numerous workers were also seen tending aphids on nearby prairie willows Salix humilis. The smooth, reddish queens, with flattened, curly golden hairs are reputed to be temporary social parasites of other Formica, with subsericea, pallidefulva the most likely candidates in the habitat where I observed them.


Not yet collected in Missouri, but a population of F. prociliata exists just a few miles away, southeast of Lamoni, Iowa, within view of the Missouri state line.
