Dipalta serpentina Osten Sacken (Diptera: Bombyliidae) as a predator on pupae of the antlion
Myrmeleon immaculatus DeGeer (Neuroptera: Myrmeleontidae) in California.
Two surface behaviors were described in the larva of the antlion
Griffiths (1985) observed that the maintenance of traps constructed by antlion
larvae of the species Myrmeleon quinquemaculatus Hagen, 1853 required a high energy cost and larvae that had their funnel destroyed had a 50[degrees] o lower growth rate compared to larvae whose funnel suffered no disturbance.
The prey was only offered on the first and fifth day of the experiments due to the fact that the prey capture rate of antlion
larvae is low in the natural environment (Hauber, 1999).

Predatory interactions between ants and antlions
(Hymenoptera: Formicidae and Neuroptera: Myrmeleontidae).
Up from any well-trodden pathway might come giant antlion
jaws, and then we are gone.
There are creatures never illustrated before, such as the giant West African antlion
and the Fruhstorfer's giant dobsonfly.
kicked dirt out of the cave further loosening the dirt under the ant's feet.
That's a hungry antlion
that is just about to latch on to its prey: an ant.
Well-studied examples include web-weaving spiders (e.g., Riechert and Gillespie 1986, Wise 1993), net-spinning caddisfly larvae (e.g., Hildrew and Townsend 1980, Richardson 1984, Malmqvist and Bronmark 1985), and pit-building antlion
larvae (e.g., Wheeler 1930, Lucas 1982, Heinrich and Heinrich 1984).
Like something from a horror movie, the antlion
lies in wait at the bottom of the trap, ready to grab the prey in hook-like mandibles and drain its bodily fluids.
foraging: tracking prey across space and time.

has been uncovered.)
Arthropod predators (commonly encountered taxa included sunscorpions [Solifugae], spiders [Araneae], centipedes [Scolopendridae], certain katydids [Tettigoniidae], praying mantids [Mantidae], lacewings [Hemerobiidae and Chrysopidae], antlions
[Myrmeleontidae], robber flies [Asilidae], certain ants [Formicidae], and many bugs [Hemiptera] and beetles [Coleoptera]) and parasitoids (mainly wasps [Hymenoptera]) were hand picked or aspirated from the six creosotebushes per site that were assigned to the arthropod predator-removal treatment.
