The ants clean each other's exoskeletons to decrease the presence of spores attached. [11] Also, ants can sense that a member of the colony is infected; healthy ants carry the O. unilateralis-infected individual far away from the colony to avoid exposure to spores. There are also reports that most worker ants remain inside the nest boundaries ...
[32] 51% of people who relocated themselves to infested areas report getting stung within three weeks after arrival. [33] In a survey conducted in South Carolina, 33,000 people (or 94 per 10,000 population) received medical attention due to red imported fire ants, and 660 people (1.9 per 10 000 population) were treated for anaphylaxis.

In the 1930s, colonies were accidentally introduced into the United States through the seaport of Mobile, Alabama.Despite earlier views that cargo ships from Brazil docking at Mobile unloaded goods infested with the ants, [1] recent DNA research confirmed that the likely source population for all invasive S. invicta in the United States occurred at or near Formosa, Argentina, and virtually ...
Dasymutilla occidentalis (red velvet ant, eastern velvet ant, cow ant or cow killer) [2] [3] [4] is a species of parasitoid wasp that ranges from Connecticut to Kansas in the north and Florida to Texas in the south. Adults are mostly seen in the summer months.
The toxicity of the venom of the Maricopa harvester ant is well known. Its LD 50 value is 0.12 mg/kg (injected intravenously in mice); 12 stings can kill a 2-kg rat. In comparison, the LD 50 of the honey bee is 2.8 mg/kg—less than one-twentieth as strong. In humans, a Pogonomyrmex sting produces intense pain that can last up to four hours. [3 ...
In ants, social conflicts, sex conflicts, or caste conflicts can exist. These conflicts occur within the same colony or supercolony at various levels: on an individual scale, between two or more specific ants; on the scale of sex, between males and females; or on the scale of different castes, between queens and workers.
Crematogaster ants "are able to raise their abdomens forward and over their thoraces and heads, which allow them to point their abdominal tips in nearly all directions", [11] "as if they were performing a balancing act", [12] thus they are colloquially known as cocktail ants or acrobat ants.
The type species of genus Formica is the European red wood ant Formica rufa. [1] Ants of this genus tend to be between 4 and 8 mm long. [4] Ants belonging to the Formica genus possess a single knob or bump located between their thorax and abdomen. These ants primarily feed on honeydew, a sugary liquid produced by aphids.
