The pupal case of the Palearctic robber fly Andrenosoma atrum (Linnaeus) is described, illustrated, and compared with those of Andrenosoma albopilosum Villeneuve and Andrenosoma bayardi Séguy. A key to the pupal cases of these three species is provided. Source

Proctacanthus fulviventris Macquart, 1850 (during 214 hours of observation) foraged primarily from the ground, capturing and immobilizing prey in flight. Identified prey came from two insect orders (Diptera and Hymenoptera), with Hymenoptera making up 88%. Mating occurred in the male over female position and oviposition was in the ground, typically in the shade of vegetation or a shaded depression in the ground when the sun was shining. This species exhibited a distinct daily rhythm of activity for feeding, mating, and oviposition. Grooming behavior resembled that described for other species of Asilidae. Habitats, resting behavior, and predators and parasites also are discussed. Source

The oviposition, eggs, emergence of first instar larvae, and larvae of Mallophora orcina (Wiedemann, 1828) are described and compared with those of Mallophora spp., Megaphorus spp., and other species of robber flies. Oviposition occurred on vegetation 1-3 m above the ground with approximately 188-323 eggs deposited in layers in a chalky-white albumin. The eggs are elongate and initially glistening white. They turn a dark metallic color on the end where larvae emerge from. Upon emergence the larvae drop to the ground where they bury themselves in the soil. Larvae are shiny white, dorsoventrally flattened, tapering at each end, with a distinct head, 3 thoracic segments, and 9 abdominal segments. The separation between most segments is not visible or clearly delineated. Source

Diogmites crudelis Bromley, 1936 (during 106 hours of observation) foraged from the ground and vegetation, capturing and immobilizing prey in flight. Identified prey came from three insect orders (Diptera, Hemiptera, and Hymenoptera), with Hymenoptera making up 81.7%. Mating occurred in the tail-to-tail position and oviposition was in the ground, typically in the shade of vegetation when the sun was shining. This species exhibited a distinct daily rhythm of activity for feeding from 10:00 AM to 3:00 PM and oviposition from 10:00 AM to 1:00 PM. Habitats, resting behavior, grooming behavior, and predators and parasites also are discussed. Source

Stichopogon trifasciatus (Say, 1823) foraged from the ground, and rocks and small sticks on the ground. Most prey were captured and immobilized in flight. Prey came from the orders Araneae (1.4%), Coleóptera (1.4%), Diptera (26.1%), Hymenoptera (2.9%), Lepidoptera (1.4%), and Orthoptera (66.7%). Mating was generally preceded by male courtship and occurred in the male over female position. Eggs were laid in the soil. The daily rhythm of activity consisted of peaks for both mating and feeding in the morning and afternoon, although after the morning peak these behaviors steadily decreased. Grooming behavior was similar to that described for other species of Asilidae. Habitat, resting behavior, and predators and parasites also are discussed. Source
