Epeolus
variegated cuckoo-bees, cellophane-cuckoo bees
Epeolus is a genus of medium-sized cleptoparasitic bees comprising approximately 100 described species worldwide. All known species are obligate nest parasites (kleptoparasites) of mining bees in the genus Colletes. Females lack the branched pollen-collecting hairs typical of most bees and instead possess specialized abdominal spines used to pierce the cellophane-like nest linings of their hosts. The genus is distinguished by striking black-and-white or black-white-red-yellow integumental patterns formed by short, fat hairs lying flush against the body surface.
Epeolus australus
Epeolus australus is a cleptoparasitic (cuckoo) bee in the genus Epeolus, a group of bees that do not construct their own nests or collect pollen. Like other members of its genus, this species invades the nests of host bees, primarily those in the genus Colletes (polyester bees), where it lays eggs that hatch into larvae that consume the host's provisions and offspring. The species is one of approximately 43 known Epeolus species in North America, with new species in this genus continuing to be described due to their small size, rarity relative to their hosts, and wasp-like appearance that makes them difficult to detect.
Epeolus barberiellus
Barber's Cellophane-cuckoo Bee
Epeolus barberiellus is a species of cuckoo bee in the family Apidae, first described by Cockerell in 1907. As a member of the genus Epeolus, it is a cleptoparasite that lays its eggs in the nests of host bees, primarily species in the genus Colletes (cellophane bees). The species is known from North America, though specific details about its distribution, abundance, and ecological relationships remain poorly documented compared to better-studied congeners.
Epeolus bifasciatus
Two-banded Cellophane-cuckoo Bee
Epeolus bifasciatus is a cleptoparasitic bee in the family Apidae, commonly known as the Two-banded Cellophane-cuckoo Bee. As a member of the genus Epeolus, it parasitizes nests of polyester bees in the genus Colletes, specifically targeting Colletes latitarsis. The species is distributed across Central America and North America.
Epeolus carolinus
Carolina Cellophane-cuckoo Bee
Epeolus carolinus is a species of cuckoo bee in the family Apidae, first described by Mitchell in 1962. As a cleptoparasitic bee, it lays eggs in the nests of host bee species rather than constructing its own nests or collecting pollen. The species is native to North America and is one of approximately 43 recognized Epeolus species on the continent. Like other members of its genus, it is associated with polyester bees (Colletes) as hosts.
Epeolus flavofasciatus
Yellow-banded Cellophane-cuckoo Bee
Epeolus flavofasciatus is a cleptoparasitic (cuckoo) bee in the family Apidae, first described by Smith in 1879. Like other members of the genus Epeolus, this species does not construct its own nests or collect pollen, instead laying eggs in the nests of host bees, primarily those in the genus Colletes (polyester bees). The species is characterized by its distinctive yellow-banded coloration and relatively small size. It occurs in North and Middle America, with records from the United States, Mexico, and Guatemala.
Epeolus interruptus
Interrupted Cellophane-cuckoo Bee
Epeolus interruptus is a cleptoparasitic (cuckoo) bee in the family Apidae, native to North America. First described by Robertson in 1900, this species invades the nests of polyester bees (genus Colletes) to lay its eggs. Like other cuckoo bees, females lack the branched body hairs used for pollen collection and instead rely on host bees to provision their offspring. The species exhibits reduced pilosity compared to non-parasitic bees, giving it a wasp-like appearance.
Epeolus lectoides
Sumac Cellophane-Cuckoo, cuckoo bee
Epeolus lectoides is a species of cuckoo bee in the family Apidae. It is a cleptoparasite that lays its eggs in the nests of host bees rather than building its own nest or collecting pollen. The species is found in North America and has been documented using Colletes latitarsis and Colletes nudus as hosts.
Epeolus mesillae
Mesilla Cellophane Bee
Epeolus mesillae is a species of cuckoo bee in the family Apidae, first described by Cockerell in 1895. As a kleptoparasite, it invades the nests of host bees to lay its eggs, with its offspring consuming the host's provisions. The species is recorded from North America and Middle America. Like other Epeolus species, it lacks the branched body hairs typical of pollen-collecting bees and instead exhibits color patterns of short black, white, red, and yellow hairs.
Epeolus minimus
Least Cellophane-cuckoo Bee
Epeolus minimus is a small cleptoparasitic bee in the family Apidae, commonly known as the Least Cellophane-cuckoo Bee. As a member of the cuckoo bee genus Epeolus, it invades the nests of host bees to lay its eggs, relying on host-collected pollen provisions rather than gathering its own. The species is native to North America and has been documented in the northeastern United States, including Vermont. Like other Epeolus species, it lacks the branched body hairs typical of pollen-collecting bees, giving it a wasp-like appearance.
Epeolus olympiellus
Olympia Cellophane-cuckoo Bee
Epeolus olympiellus is a cleptoparasitic (cuckoo) bee in the family Apidae. Like other members of its genus, it invades the nests of polyester bees (genus Colletes) to lay its eggs, with the resulting larvae killing the host's offspring and consuming the stored pollen. The species is found in North America and was described by Cockerell in 1904.
Epeolus scutellaris
red-chested cuckoo nomad bee, Notch-backed Cellophane-cuckoo Bee
Epeolus scutellaris is a cleptoparasitic bee in the family Apidae. As a cuckoo bee, it does not construct nests or collect pollen, instead laying eggs in the nests of host bees. The species occurs in North America and Mexico. It is one of approximately 43 Epeolus species recognized in North America.
Epeolus splendidus
Splendid Cellophane-cuckoo Bee
Epeolus splendidus is a cleptoparasitic (cuckoo) bee species described by Onuferko in 2018. As a member of the genus Epeolus, it invades the nests of polyester bees in the genus Colletes, where females lay eggs that hatch into larvae that kill the host egg or larva and consume the stored pollen. The species name 'splendidus' refers to its attractive appearance, characterized by short black, white, red, and yellow hairs forming distinctive patterns. Like other Epeolus species, it lacks the branched hairs typical of pollen-collecting bees due to its parasitic lifestyle.
