Hylaeus floridanus
(Robertson, 1893)
Florida Masked Bee
Hylaeus floridanus is a of masked () in the . Like other members of its , it is nearly hairless and -like in appearance, transporting pollen and nectar internally in a rather than externally on body hairs. Females nest in pre-existing cavities such as hollow stems or twigs, lining with a secreted . The species is to Florida and the southeastern United States.

Identification
Distinguished from by (branched) body hairs visible at 60× magnification or greater, though this requires microscopic examination. Separated from other Hylaeus by geographic range and subtle morphological characters. The nearly hairless, slender body and facial markings are field characters. Males may be confused with wasps due to pale, colored and lack of obvious pollen-carrying structures.

Habitat
Associated with areas providing pre-existing nesting cavities: hollow stems, twigs with pithy centers, or abandoned burrows. Found in natural and semi-natural in Florida, including coastal and subtropical environments.
Distribution
to southeastern United States, with records from Florida. Distribution records indicate presence in North America; specific range appears centered on Florida based on epithet and distribution patterns.
Diet
feed on nectar. provisioned with regurgitated nectar and pollen stored in nest . Specific floral associations for this are not documented; members are generally considered with some species showing preferences for Rosaceae or Asteraceae when available.
Life Cycle
Solitary nesting: each female constructs and provisions her own nest. Nests established in pre-existing cavities (hollow stems, twigs, abandoned burrows). lined with secreted (natural plastic) to prevent spoilage of stored provisions. Single develops per cell, feeding on stored pollen-nectar mass.
Behavior
Females forage for nectar and pollen, which are carried internally and regurgitated into nest . Males may aggregate near nesting sites. Will utilize artificial nest boxes (bundled straws, drilled blocks) if provided. Non-aggressive; lacks functional .
Ecological Role
, though contribution to specific is poorly documented due to internal pollen transport. Provides food source for nest and . Nesting in pre-existing cavities may facilitate in dead plant material.
Human Relevance
Potential beneficiary of efforts and artificial nest box programs. Like other native bees, may contribute to of wild plants and , though specific documentation for this is lacking. Not known to be a pest or nuisance species.

Conservation context
The Hylaeus has experienced significant declines in some regions. Seven Hawaiian Hylaeus are considered critically imperiled and possibly extinct, primarily due to on , , and . While H. floridanus itself has no documented status, this highlights vulnerability of the genus to disturbance and .
Nesting biology
The -lining secretion produced by females is a remarkable example of natural production. This plastic creates a waterproof, antimicrobial barrier that preserves larval food stores, analogous to cellophane or plaster in human materials—hence the '' for the .
