Eastern Missouri, 38.5 deg. N., USA. Lasius neoniger flew 28 October 2014, in calm, sunny weather with temperature in the low 80's F (upper 20's C). This is the "Labor Day Ant" (flies around the first Monday in September) in the north, but in peninsular Florida, it could be called the "Thanksgiving Day Ant" (last Thursday in November) (James Trager).
