I saved this colony from a neighbor's spray-poison the other day, but I am not sure what species it is. Based on preliminary research using AntWeb.org and Google Earth, I have a few contenders (C. discolor, C. floridanus, C. tortuganus); however, I would like to be certain before I get them settled and begin a feeding regimen. I have posted pictures and answered some preliminary questions below. I hope this is enough to lead you experts to the answer.
Thank you in advance for any help.
Miami, FL USA 33138 (07/01/2012)
SECOND-Habitat of collection, including nesting medium (wood, soil, leaves tied together with silk, etc.) and type of vegetation (forest, grassland, park/lawn/garden, desert).
In a wooden birdhouse on a fence post surrounded by a Passiflora vine.
THIRD-Coloration, hue and pattern? Uniform?, Head darker?, Gaster darker?, Legs lighter or darker?, Any spots? Also, shininess, dullness.
[See images for better description.] Head and thorax the color of Chicago brick (red/orange). The gaster is black. Legs appear the same color as the thorax. They are neither shiny nor dull.
FOURTH-Distinguishing characteristics, such as one or two segments in waist; location, length and orientation of any spines or bumps on the mid portion of the body or waist; head shape, etc.
One segment in waist. The mid portion of the body seems smooth except for the lines where the exoskeleton meets. The head is smooth and rounded at the top when viewed from the side, but the head is more triangular in shape, the hypotenuse of which forms the top of the head opposite the mandibles.
FIFTH-Length in millimeters. (Width is also helpful.) NO guessing! Stretch out a dead or chilled individual or several individuals of different sizes along a millimeter rule. 16ths of an inch will do as a poor second to millimeters.
It is 12 mm stretched out when dead. The one in the picture “camponotus id 5” is 10 mm non-stretched. I have not measured one live.
SIXTH-Anything else distinctive, such as odor, behavior, etc.
They are nocturnal. They appeared to have been sharing a nest with a very big colony (at least 5,000) of Tapinoma melanocephalus. They love honey.
