Lasius minutus

Emery, 1893

Mound-building Swamp Ant

Lasius minutus is a of in the Lasius, commonly known as the Mound-building Swamp Ant. It is a small formicine ant that constructs mounds in wetland . The species has been studied using radioactive phosphorus tracing to understand colony distribution and spatial organization. It belongs to a genus known for citronella-scented defensive compounds and -tending behaviors, though species-specific traits for L. minutus require direct observation.

Identification

Lasius minutus can be distinguished from by its , narrow waist between and , and larger than in winged forms. Within the Lasius, identification to level requires examination of morphological characters such as size, pilosity, and structure; specific diagnostic features for L. minutus versus like L. alienus or L. neoniger are not provided in available sources.

Appearance

Small typical of the Lasius. are likely pale to brownish in coloration, consistent with related in the genus. As with all Lasius, possesses elbowed () , a narrow (-waist) between and , and a compact body form. Winged reproductive forms, when present, have larger than with few prominent .

Habitat

Wetland and swamp environments, as indicated by the 'Mound-building Swamp '. Constructs mounds in moist, poorly drained soils. Specific microhabitat preferences within wetlands (e.g., hummocks, edges, saturated soils) are not documented in available sources.

Distribution

Recorded from Vermont, United States based on distribution data. Broader North range not specified in available sources; likely occurs in northeastern United States and possibly adjacent Canada given preferences and related distributions.

Behavior

Colony distribution and spatial organization have been studied using radioactive phosphorus as a tracer, indicating movement patterns and territorial structure. Specific behaviors such as foraging, nesting, or defensive responses are not documented in available sources.
