Young at The University of Tennessee Forestry Experiment Station and Arboretum, Oak Ridge, Tennessee for their assistance in establishing the research sites, and to the formicid
Bacteria related to Blochmannia infect the formicid
genera Formica, in which the presence of symbionts varies among species, and Plagiolepis, which is poorly studied to date (reviewed in Dasch et al.
Thus small size, one of the most distinctive traits of formicid
inquilines, may have been selected not for its own sake, but rather as a mechanism to insure that larvae become queens.

Our results are based on ant specimens collected in 2002 in the course of investigations on the eucharitid fauna associated with formicids

The ant subfamily Pseudomyrmecinae (Hymenoptera: Formicidae): generic revision and relationship to other formicids
Pitfall traps are efficient and cost effective for passively capturing insects for many ecological studies, and have been used extensively for population studies of numerous ground-dwelling arthropods, including arachnids, formicids
, Coleoptera and most notably carabids (Southwood 1978; Post et al.
Formicids and coleopterans were consistently abundant in stomachs (Table 1).
jarrovii abruptly shifted in autumn, with considerable increase in isopterans and decrease in formicids (Tables 1 and 2).
jarrovii abruptly shifted in autumn, with isopterans increasing considerably and formicids decreasing.
Diets switched apparently from a majority of ants and coleoptera (42% and 18% by biomass respectively) (Davidson, 1956) to diplopods and coleoptera (55% and 8% by biomass) at one site and diplopods, formicids
and chilopods (31%, 10%, and 9% by biomass) at yet another (Powders and Tietjen, 1974).
