'''Paratrechina''' is an ant genus from the [[subfamily]] [[Formicinae]] ([[Tribe (biology)|Tribe]] [[Plagiolepidini]]).
There are over 150 described species and subspecies, some of which occur on every continent (except [[Antarctica]]). They form large colonies in open soil or under rocks or other objects, or in rotten wood on the ground.
Specifically ''[[Paratrechina longicornis]]'' occurs around the world, involuntarily transferred by humans, and is a common house pest in tropical climates. It is commonly called the '''crazy ant''', for its erratic movement. The ants' were included in [[Biosphere 2]],<ref>{{cite web
