Egg placement —We recorded the area of egg placement on the prey 
larvae for 28 of the 31 unhatched eggs excavated from nests at 
Cornish. Four eggs were placed on the thorax (two between the first 
and second segments and one each on the first prothoracic segment 
and between the first and second segments); 24 eggs were placed on 
the abdomen (seven each on the first and second segments, two on the 
third segment, three on the fourth segment, and five on the first 
proleg; two eggs were laid in one cell). 
Cleptoparasitism and prey stealing —In some species of aculeate 
Hymenoptera, females no longer build nests or forage for food for 
their offspring. Instead, the nests of females of other species are 
located and the food stored by these hosts is utilized to rear the
