Hylaeus affinis
eastern masked bee
Hylaeus affinis, commonly known as the eastern masked bee, is a small solitary bee in the family Colletidae. It is native to North America and belongs to the genus Hylaeus, whose members are often called masked bees or yellow-faced bees due to their distinctive facial markings. Like other Hylaeus species, it is nearly hairless and resembles small wasps in appearance. The species nests in pre-existing cavities and transports pollen and nectar internally rather than on body hairs.
Hylaeus basalis
Cinquefoil Masked Bee
Hylaeus basalis is a solitary bee species in the family Colletidae, commonly known as the Cinquefoil Masked Bee. It is native to North America and belongs to the genus Hylaeus, a group of nearly hairless bees often mistaken for wasps. Like other masked bees, females lack pollen-carrying structures and instead transport nectar and pollen internally in a crop, regurgitating food stores at the nest. The species has been documented in Colorado and Vermont.
Hylaeus communis
Common Masked Bee
Hylaeus communis is a small, nearly hairless solitary bee native to the Palearctic region and recently introduced to North America. It is one of the most common and adaptable species in its genus, exhibiting extreme generalism in habitat use and floral visitation. Females transport nectar and pollen internally in a crop, rather than on body hairs, and nest in pre-existing cavities. The species is partially bivoltine with flight activity from late May through September.
Hylaeus episcopalis
Episcopal Masked Bee
Hylaeus episcopalis is a species of masked bee in the family Colletidae, first described by Cockerell in 1896. Like other members of its genus, it is a solitary, nearly hairless bee that transports pollen and nectar internally rather than on body hairs. The species occurs in North America and is one of approximately 50 Hylaeus species on the continent. Four subspecies have been described: H. e. coquilletti, H. e. episcopalis, H. e. giffardiellus, and H. e. metzi.
Hylaeus episcopalis coquilletti
Hylaeus episcopalis coquilletti is a subspecies of yellow-faced bee in the family Colletidae. As with other members of the genus Hylaeus, this bee is nearly hairless and wasp-like in appearance, lacking the dense hair typical of most bees. Females have distinctive yellow or white markings on the inner margin of each eye, while males have the entire face colored yellow or white. These solitary bees nest in pre-existing cavities such as hollow stems or twigs, lining cells with a natural polymer secretion. The subspecies epithet "coquilletti" honors the entomologist James Charles Coquillett.
Hylaeus euxanthus
Yellow-collared Masked Bee
A small, nearly hairless bee in the family Colletidae, native to Australia and introduced to Argentina. First described by Cockerell in 1910, it was originally named Prosopis xanthopoda but renamed due to preoccupation. It belongs to the subgenus Gnathoprosopis and exhibits typical masked bee characteristics including reduced pilosity and internal pollen transport.
Hylaeus fedorica
Hylaeus fedorica is a species of masked bee (yellow-faced bee) in the family Colletidae. The species was described by Cockerell in 1909.

The species is poorly known due to its restricted range and limited study.
Hylaeus hyalinatus
Hairy masked bee
Hylaeus hyalinatus is a species of masked bee in the family Colletidae. It is native to Europe, including Great Britain, and has been introduced to North America where it is considered invasive. Like other members of genus Hylaeus, it is nearly hairless and wasp-like in appearance, with females transporting pollen and nectar internally rather than on body hairs.
Hylaeus leptocephalus
Slender-faced Masked Bee
Hylaeus leptocephalus is a small solitary bee in the family Colletidae, commonly known as the Slender-faced Masked Bee. Native to the Palearctic region, it has been established in North America since 1912. Like other masked bees, it is nearly hairless and transports pollen and nectar internally rather than on body hairs. The species nests in pre-existing cavities such as hollow stems and twigs.
Hylaeus mesillae
Mesilla Masked Bee
Hylaeus mesillae, commonly known as the Mesilla Masked Bee, is a solitary bee species in the family Colletidae. It is distributed across Central America and North America. Like other members of the genus Hylaeus, it is nearly hairless and often mistaken for small wasps. The species was first described by Cockerell in 1896 and includes three recognized subspecies.
Hylaeus mesillae cressoni
Cresson's Masked Bee
Hylaeus mesillae cressoni is a subspecies of masked bee in the family Colletidae. Like other members of the genus Hylaeus, it is nearly hairless and often mistaken for a small wasp. The species is distributed in North America and Middle America. As a solitary bee, each female constructs her own nest in pre-existing cavities such as hollow stems or twigs.
Hylaeus modestus
modest masked bee, yellow-faced bee
A small, nearly hairless solitary bee in the family Colletidae, native to North America. Females transport pollen and nectar internally in a crop, then regurgitate it into brood cells lined with a secreted polymer. The species has been observed visiting annual flowers in garden settings and is a generalist forager. A gynandromorph specimen with bilaterally asymmetric male and female characteristics was documented from Ontario, Canada.
Hylaeus modestus citrinifrons
