Specimen Label

Synonyms

A New World subterranean army ant with an extensive geographic range. The range of L. coecus appears to be essentially continuous, from Buenos Aires, Argentina in the south (~34.6°S) to Delaware County, Oklahoma in the north (~36.6°N). The three West Indian islands with L. coecus populations are all continental shelf islands that were connected to South America during periods of lower sea levels a few thousand years ago, so L. coecus populations on these islands have only recently become isolated. Labidus coecus commonly nests in caves, a microhabitat that may allow it to live in regions with otherwise inhospitable climates. Although recent papers listed L. coecus as an exotic species in North America, we found no evidence that L. coecus is exotic to any part of its known range. (Wetterer and Snelling 2015)

Identification

Distribution

Wetterer and Snelling (2015) - L. coecus has been reported from 20 countries in Central and South America (all except Chile), three West Indian islands (Margarita, Trinidad, and Tobago), and four US states (Arkansas, Louisiana, Oklahoma, and Texas). The range of L. coecus appears to be essentially continuous, from Buenos Aires, Argentina in the south (~34.6°S) to Delaware County, Oklahoma in the north (~36.6°N).

Biology

Baudier et al. (2015) studied thermal tolerances of a variety of army ant workers. Labidus coecus was one of two army ant species sampled that are strictly subterranean, i.e. both bivouac and raid underground.
