Cell size [N = 26] at Base Borden varied regardless of year: length [Range = 14-22 mm, Mean = ± ], width [Range = 13-15 mm, Mean = ± ], height [Range = 12- 15 mm, Mean = ±]. Cell contents From five to nine prey [Mean = ± , N = 18] were stored in fully provisioned cells at Base Borden. Individual prey weight ranged from to mg [Mean = ± , N = 132]. Two wasps from Base Borden [voucher specimens] weighed 147 and 151 mg. One noctuid prey from Fort Drum weighed 93 mg. Ag- gregate prey weight per cell from Base Borden ranged from to mg [Mean = ± , N = 18]. One cocoon from Base Borden, 69 mm deep, was 7 mm wide and 17 mm long, weighed mg, and reared a male wasp. Two cocoons from Base Borden, 72 and 73 mm deep, were each 8 mm wide and 19 mm long, weighed and mg, respectively, and reared female wasps. Of 132 prey in the cells, 78 () were positioned head inward and ventral side upward. Fifty-four () of the prey were placed head inward and on the side. Females preyed on adults of seven species of Noc- tuidae and one species of Hesperiidae. Of 132 prey specimens, 124 () belonged to the family Noc- tuidae and eight () belonged to the family Hes- periidae (Table 2). Some prey species were associated with barren sandy and/or fire- adapted habitats. Prey individuals were probably captured on flowers or low growing herbaceous vegetation. Egg Stictiella emarginata eggs from four females at Base Borden in 1998 were approximately 4 mm long and 1 mm wide [N = 11]. Two recently laid eggs weighed mg while a one day-old wasp larva weighed mg. Eggs or 1st instar larvae were attached to the base of the prey's abdomen near its co
