The tarantula hawk wasp Hemipepsis ustulata is a lek-forming insect whose males defend certain conspicuous shrubs and trees growing on mountain ridges in Arizona, even though these plants provide no resources of utility to males or females (Alcock, 1979, 1981).

Hilltopping behaviour and mating success of the tarantula hawk wasp, Hemipepsis ustulata (Hymenoptera: Pompilidae), at a high elevation peak.
Although in 1 y (1998) all figures were higher (except for the average tenure of resident males), in the other 5 y of the study the population of tarantula hawk wasps behaved very similarly, such that the various parameters measured were highly similar from year to year.
Similarity in the distribution of male sizes probably stems from a similar distribution in prey sizes selected by female tarantula hawk wasps from year to year, as the weight of the offspring is almost certainly largely a function of the amount of provisions provided by its mother (Dow, 1942; Klostermeyer et al.
