Collectively, these observations suggest that both space and food may be limiting resources for ant lion larvae.
Larvae were held in plastic dishes (12 cm diameter, 2 cm depth) filled with 270 g of oven-dried sand collected from the ant lion zone.
Dishes were randomly placed on the soil surface in the ant lion zone.
Each cup was buried in the ant lion zone with the lip of the cup flush with the adjacent sand surface.
Daily, each ant lion larva with a pit was fed one Tribolium confusum larva.
Effects of year, site, third-instar larvae, and sham ant lion pits on recruitment of first-instar M.
In summary, ecologists and naturalists have long emphasized the unique adaptations of ant lions for capturing prey.
In this study, I examine the distributional and behavioral responses of an assemblage of ground-foraging ants to high-density aggregations of predaceous ant lion larvae (Neuroptera: Myrmeleontidae).
Large and small traps were placed both within and 1 m beyond the ant lion zone [ILLUSTRATION FOR FIGURE 1 OMITTED].
I then rarefied this collection down to an equivalent number of individuals collected from the six stations within the ant lion zone.
During July of 1992, I mapped all nest entrances that could be found within and adjacent to the ant lion zone at each site along a 10-15 m transect parallel to each cliff ledge.
For several ant species at the Pugh Canyon site, I estimated the probability of death by introducing foragers into the ant lion zone.
