Distribution
Solenopsis geminata and Solenopsis xyloni, the tropical and the southern fire ants, respectively, are native to the southeast region of Texas. The tropical fire ant ranges across most of the eastern part of the state. The southern fire ant ranges across the east and some of southwest Texas as well. If southern fire ants are present in a given area, it is extremely unlikely any other species of fire ants also live in that area.
Identification
The tropical fire ant is a red-brown color, with a larger head than the southern. The southern ants closely resemble the red imported ants and are often mistaken for them. Southern fire ants are medium-sized ants. Most of their bodies are amber, with a black end segment. Both species have small hairs covering their bodies.
Food and Homes
Fire ants usually eat foods rich in proteins and oils. Fruit, and live and dead animals, are the major food sources. Seeds are also a major component of a fire ant's diet, particularly tropical ants. Both species make their homes in soil, and usually have multiple entrances consisting of small mounds. They are often found around farmland or in neighborhood areas.
Dangers
Fire ants as a whole are aggressive. Both the tropical and the southern species have stingers, which they do not hesitate to use. They readily sting animal and human alike if they feel threatened. The stings are painful and are often caused by more than one ant. Medical care is sometimes required.
