Small honey ant

Definition

A common name for Prenolepis imparis, a North American ant species in the subfamily Formicinae, notable for being among the earliest ants to forage in late winter and early spring. Workers are small, pale yellow to brown, and possess a highly distensible gaster that can swell dramatically when engorged with liquid food, giving the abdomen a translucent, honey-filled appearance. The species is primarily nectarivorous and honeydew-feeding, storing carbohydrates in the crop and regurgitating them to nestmates during periods of dearth.

Etymology

English vernacular; 'honey' refers to the amber, honey-like appearance of the distended gaster when filled with stored liquid food.

Example

In temperate deciduous forests, small honey ant workers emerge from hibernation on the first warm days of February or March, often foraging at temperatures near freezing when other ant species remain dormant; their enlarged gasters allow them to stockpile sufficient reserves to feed the colony until more consistent spring foraging becomes possible.

Synonyms

• winter ant
• false honey ant

Related Terms

• Prenolepis
• Formicinae
• Replete
• crop
• Trophallaxis
• Overwintering
• cold-tolerance foraging

Usage Notes

The common name is somewhat misleading, as the species does not produce true honey; rather, workers store dilute nectar and honeydew. The name 'winter ant' is increasingly preferred in ecological literature to emphasize their unusual phenology. Not to be confused with true honey ants (Melophorus, Myrmecocystus, and other genera) of Australia and western North America, which have specialized replete castes that serve as living storage vessels.
