Lasius is a genus of formicine ants. [2] The type species for this genus is the black garden ant, Lasius niger. Other major members, which live in drier heathland, are the cornfield ant, L. neoniger, and L. alienus. Other species include the temporary social parasites of the L. mixtus group and the hyper-social parasite Lasius fuliginosus.

Mar 28, 2025 · Lasius is one of the most prominent and familiar of the Holarctic ant genera. From the time of Reaumur in the eighteenth century (Wheeler, 1926), European and North American entomologists have focused attention on it in countless general biological and taxonomic investigations which are today part of the classical foundation of myrmecology.

The black garden ant (Lasius niger), also known as the common black ant, is a formicine ant, the type species of the subgenus Lasius, which is found across Europe and in some parts of North America, South America, Asia and Australasia.

Dec 27, 2024 · This species is a host for the temporary parasites Lasius carniolicus, Lasius citrinus, Lasius meridionalis (unconfirmed), Lasius mixtus (unconfirmed), Lasius rabaudi, Lasius sabularum (unconfirmed) and Lasius umbratus.

Lasius fuliginosus, also known as the jet ant or jet black ant, is a species of ant in the subfamily Formicinae.

Mar 4, 2024 · Lasius - 'fuzzy or hairy,' a characteristic of some of the most common species (but many are shiny).

Feb 26, 2024 · This species is replaced in nearly every available habitat except woodland by the equally successful and abundant members of the Lasius neoniger complex. Lasius pallitarsis occupies the same types of nesting sites as americanus and probably limits its northward spread.

Identifying Lasius is surprisingly difficult. Good magnification is key. Species are broken up into four groups. Niger tend to be dark black brown workers and sometimes amber-orange in color. Flavus, Umbratus, and Claviger all have orange workers, …

Aug 30, 2024 · Lasius alienus (Förster) has long been applied to the Nearctic population. Schar, et al 2018 (see print references) at long last elevated this species out of the Eurasian taxon L. alienus.)

Jan 10, 2022 · Here, we integrate morphology and molecular data to holistically address the evolution, classification, and identification of the ant genus Lasius, its tribe Lasiini, and their subfamily Formicinae.
