入侵的花园蚂蚁，Lasius疏忽在欧洲和亚洲的扩张过程中描述：a）通过殖民地增长测量的四个超级殖民地（塞瓦，德布勒森，布达城堡和Budateteny）从两个遥远的和气候不同的国家（西班牙，匈牙利），和B）区域扩张，使用数据从所有公布的和几个新的非本地的地方。短的局部距离过程（几米到89米年-（1）），如殖民地萌芽，比长的区域距离（10公里到> 1000公里）小2到5个数量级。这表明人类直接干预了入侵性传播。区域趋势还表明，在过去的30年里，入侵花园蚂蚁已经迅速而稳定地增加了非本土地区（77个）和国家（14个）的数量。
The expansion process of the invasive garden ant, Lasius neglectus in Europe and Asia is described in terms of: a) local expansion through colony growing measured on four supercolonies (Seva, Debrecen, Buda Castle and Budateteny) from two distant and climatically different countries (Spain, Hungary), and b) regional expansion, using data from all published and several new non-native localities. Short, local distance processes (few meters to 89 m year-(1)), as colony budding, are two to five orders of magnitude smaller than long regional distances (ten km to > 1000 km). This suggests direct human intervention in the invasive spread. The regional trend also shows that the invasive garden ant has been quickly and steadily increasing the number of non native localities (77) and countries (14) it has reached during the last 30 years.
