Because there are no loose pit walls, striking prey with sand cannot have the dislodging effect that Myrmeleon rely upon to bring prey within striking distance.
The pit-trapping foraging strategy of the ant lion, Myrmeleon immaculatus DeGeer (Neuroptera: Myrmeleontidae).
Given that the larvae Myrmeleon brasiliensis (Navas, 1914) select protected sites to build their traps and that trap maintenance has a high energy cost (Lima and Faria, 2007), we expected that constant maintenance and reconstruction of the trap would negatively affect larval development and the adult emergency conditions since the larvae would cease to accumulate the energy resources required for their full development.
Myrmeleon brasilienses larvae were collected in Aquidauana, Mato Grosso do Sul, Brazil, in an Area of Permanent Protection (APA) (20, 26'25"S, 55, 39'21"W) belonging to the State University of Mato Grosso do Sul.
Day and Zalucki (2000) found that the minimum distance between Myrmeleon acer Walker larvae under conditions of high density was similar to the distance that grains of sand reached during the building of a funnel trap (30 mm).
Effect of density on spatial distribution, pit formation and pit diameter of Myrmeleon acer Walker, (Neuroptera: Myrmeleontidae): patterns and processes.
Key words: Antlion behaviour, Myrmeleon formicarius, pit size, Neuroptera.
Antlions of the species Myrmeleon formicarius are best known for the ability of their larvae to build inverted conical pits in dry, loose, fine grained soil.
Abstract: Myrmeleon brasiliensis larvae are predators that use the sit-and-wait tactic to catch their prey, and to fulfill this pit-making funnel traps in the sandy soil and remain buried waiting for prey to slip.
Predation behavior of the Myrmeleon brasiliensis (Neuroptera: Myrmeleontidae) larval instars
Combining the development of a predictive model with a laboratory experiment, we recently addressed the issue of foraging through space and time in a study of Myrmeleon immaculatus (Linton et al.
At SBD-NL, the locations of antlion pits are not significantly correlated with prey abundance, as measured by unfiltered pitfall trap data (Linton 1995); larvae of Myrmeleon immaculatus actually seem to track sources of shade or cover more strongly than sources of food (Klein 1982, Lucas 1989, Linton 1995).
