Halictus poeyi

Lepeletier, 1841

Poey's Furrow Bee

Halictus poeyi is a primitively sweat in the , commonly known as Poey's furrow bee. The exhibits notable geographic variation in colony cycle : northern and central Florida are with annually brooded colonies, while southern Florida and Florida populations are with continuously brooded colonies. This plasticity appears driven by environmental conditions rather than genetic differentiation. Males form nighttime roosting clusters on vegetation, showing area fidelity within approximately 1.5 meters. The species is morphologically indistinguishable from Halictus ligatus, requiring genetic or detailed behavioral analysis for separation.

Habitat

Found in areas supporting Bidens pilosa and Emilia sonchifolia vegetation for male roosting; nests in soil. Northern and central Florida occupy regions with seasonal conditions favoring cycles; southern Florida and Florida populations occur in environments supporting continuous .

Distribution

Southeastern United States (Florida: northern, central, and southern regions including Florida ); Jamaica, Antilles; Caribbean region.

Host Associations

Bidens pilosa - Male roosting siteUsed for nighttime sleeping , not confirmed as pollen or nectar source
Emilia sonchifolia - Male roosting siteUsed for nighttime sleeping , not confirmed as pollen or nectar source

Life Cycle

Primitively with two distinct colony cycle phenotypes: (1) with annually brooded colony cycle in northern and central Florida; (2) with continuously brooded colony cycle in southern Florida and Florida . Colonies founded in spring by overwintered females.

Behavior

Males form nighttime roosting clusters on floral plants, exhibiting area fidelity within approximately 1.5 meter rather than fidelity to specific individuals or . Roost site selection influenced by microhabitat structure, sunlight exposure, weather conditions, and plant structural characteristics. Primitively social structure with and daughters.

Similar Taxa

Behavioral plasticity

The expression of versus colony cycles in Halictus poeyi is influenced by environmental conditions (temperature, food availability) rather than genetic isolation between . Genetic differentiation (FST) between populations with different phenotypes was not significantly higher than between populations with similar phenotypes.

Male roosting observations

In Jamaica, male roosting clusters were observed over approximately 50 days with no emerging or nesting females found near the roosting sites, suggesting spatial separation between male roosting areas and female nesting activity.
