Apiomerus flaviventris
Yellow-bellied Bee Assassin, bee assassin bug
Apiomerus flaviventris is a predatory assassin bug in the family Reduviidae, commonly known as the yellow-bellied bee assassin. This species is notable for its specialized feeding habits targeting bees and its remarkable use of plant-derived chemical defenses. Females collect resin from brittlebush (Encelia farinosa) and apply it to their eggs as a protective barrier against predation, particularly by ants. The species inhabits arid and semiarid regions of southwestern North America.
Philanthini
Philanthini is a tribe of wasps within the family Crabronidae, established by Latreille in 1802. Members are commonly known as beewolves or bee-killer wasps due to their specialized predatory behavior. The tribe includes genera such as Philanthus, which are notable for their distinctive hunting strategies and, in some species, the use of symbiotic bacteria to protect larval food stores. These wasps are solitary and nest in soil, provisioning their offspring with paralyzed bees.
Philanthus
beewolves, bee-hunters, bee-killer wasps
Philanthus is a genus of solitary predatory wasps commonly known as beewolves. Adult females excavate underground burrows in sandy soils and provision them with paralyzed bees as food for their larvae. Males are highly territorial, marking vegetation with pheromones to defend mating territories. The genus contains approximately 136 species worldwide, with about 30 species occurring in North America. These wasps are important pollinators as adults and serve as population regulators of bee communities.
Philanthus bilunatus
Two Moons Beewolf
Philanthus bilunatus is a solitary wasp in the family Crabronidae, commonly known as the Two Moons Beewolf. Like other beewolves in the genus Philanthus, it is a predator of bees and wasps, which it paralyzes to provision underground nests for its larvae. The species is found in North America, with records from Canada and the United States. As a member of the subfamily Philanthinae, it shares behavioral traits with related beewolves including territorial males and nest excavation in sandy soils.
Philanthus gibbosus
Hump-backed Beewolf, Beewolf
Philanthus gibbosus, commonly known as the hump-backed beewolf, is a solitary bee-hunting wasp and the most common and widespread member of its genus in North America. Females construct underground burrows in sandy soils and provision them with paralyzed bees as food for their larvae. The species exhibits a bivoltine life cycle with two generations per year, and shows a tendency toward temporary communal nesting behavior unusual for solitary wasps.
Philanthus lepidus
Pleasant Beewolf
Philanthus lepidus is a species of beewolf wasp in the family Crabronidae, native to North America. Like other members of the genus Philanthus, females are solitary hunters that provision underground nests with paralyzed bees as food for their larvae. The species has been the subject of limited behavioral study, with at least one published account of its nesting behavior. It is one of approximately 30 Philanthus species occurring in North America.
Philanthus multimaculatus
beewolf, bee-hunting wasp
Philanthus multimaculatus is a common North American beewolf wasp in the family Crabronidae. Females are solitary nesters that excavate burrows in sandy soil, often in aggregations with conspecifics. They provision nest cells with paralyzed bees, primarily sweat bees (Halictidae), and lay a single egg on each prey item. Males exhibit territorial behavior, perching on grass stems near nesting areas to intercept females and chase rival males. Adults visit flowers for nectar and serve as pollinators while also functioning as predators that regulate bee populations.
Philanthus pacificus
Pacific beewolf
Philanthus pacificus is a solitary wasp species in the beewolf genus Philanthus, native to western North America. As a member of the Crabronidae family, females are known to provision underground nests with paralyzed bees as food for their developing larvae. The species occurs from southwestern British Columbia through California to Baja California and Sonora, Mexico. Two subspecies are recognized: P. p. arizonae and the nominate P. p. pacificus.
Philanthus politus
beewolf
Philanthus politus is a species of beewolf wasp in the family Crabronidae, characterized by distinctive white striping. As a solitary hunting wasp, females prey on bees to provision underground nests for their larvae. The species is part of the diverse genus Philanthus, which contains approximately 30 species in North America and about 136 species worldwide.
Philanthus solivagus
Philanthus solivagus is a species of beewolf wasp in the family Crabronidae. It is found in North America, with records from Canada including Alberta. As a member of the genus Philanthus, it shares the characteristic behavior of preying on bees and other hymenopterans to provision nests for its larvae.
Philanthus ventilabris
Flat-collared Beewolf
Philanthus ventilabris is a solitary bee-hunting wasp ("beewolf") in the family Crabronidae. It occurs throughout North America and has been documented visiting flowers for nectar. Like other beewolves, females provision underground nests with paralyzed bees as food for their larvae. The species was first described by Fabricius in 1798.
Saropogon dispar
Saropogon dispar is a robber fly species in the family Asilidae, first described by Coquillett in 1902. It has been documented in Oklahoma and Texas, with observations at Natches Pond, Fort Sill, and Jefferson County. The species is notable for its association with apiaries in Texas, where it has been reported as a significant pest of bees.
