Insect
American Winter Ant
Prenolepis imparisAlso known as False Honey Ant, Winter Ant, False Honeypot Ant
American winter ants defy typical insect biology by thriving in near-freezing temperatures and retreating underground to aestivate through the warm summer months. Workers forage on tree trunks and forest floors in late autumn, winter, and early spring, gathering nectar, sap, and insect secretions while competing species remain dormant. Inside the deep subterranean nest, certain workers act as living food storage vessels, their abdomens swelling dramatically with stored liquid carbohydrates.

Responsible observation
- Observation Timing: Look for them foraging on tree trunks and sidewalks on mild winter days when other insects are absent.
- Baiting Trails: Place a drop of diluted honey or sugar water on bark to observe their abdomen-distending feeding behavior.
- Gentle Watching: Avoid digging into soil nests, as their subterranean galleries can plunge more than a meter deep.
