Lasius neglectus, the invasive garden ant, is a small brown ant, superﬁcially similar in appearance and behaviour to the common black garden ant Lasius niger (L.). Unlike L. niger, which is monogynous (each nest with a single queen) and has adjacent nests that compete with one another, L. neglectus is polygynous (each nest has many queens) and has adjacent nests that do not compete with each other. This ant probably originated from Asia Minor or Turkey (Seifert, 2000) and is thought to have been introduced into Europe with horticultural materials (Espadaler et al., 2007). It was ﬁrst identified in Budapest in 1974 (Van Loon, Boomsma & Andrasfalvy, 1990) and since then it has been found in nineteen European countries including France, Germany, Belgium and The Netherlands (Seifert, 2000; Espadaler & Bernal, 2010).
Lasius neglectus was recognised at the National Trust’s Hidcote Manor in Gloucestershire in 2009 and reported by the BBC and other media as "The Asian Super Ant" in August 2009.
Very localised. Colonies are known in Gloucestershire, Cambridgeshire, London, Yorkshire and East Sussex but could turn up in any suitable habitat.
