I have been noticing this species for a while. This solitary ant is known locally as 'tiger ant', is about 13-15 mm long and very active. An image and a few video clips (http://tinyurl.com/TigerAnt). An ID would be highly appreciated. Thanks. Alex Popovkin -12.01 -38.01 http://tinyurl.com/popovkin twitter @popovkin
