	Ant - Search View - MSN Encarta
		The ant body consists of head, thorax, and abdomen, with the abdomen articulated to the thorax by means of an abdominal pedicel, or stalk.
		Typically a “finder” ant, which forages for food, arouses the colony, and excited nestmates may be influenced in their direction of progress from the nest by one means or another, according to species.
		Ants, particularly certain aphid-tending species, are frequent pests around lawns and gardens; however, the great benefit of these and other ants in aerating and mixing the soil must also be considered.

	Harvester Ants
		The main sources of food for harvester ants are seeds of different types of grasses and the bodies of insects and spiders (arthropods).
		Harvester ants are very aggressive, but one reptile has the perfect defense: the armor of the horned lizard or "horny toad." Horned lizards feed almost exclusively on harvester ants.
		The ants were part of an experiment to observe and study the effects of space flight and a weightless environment on the tunneling behavior of ants during a 16-day space shuttle flight.

	Harvester ants
		Western harvester ant mounds may be 1-4 ft. across, and 2-10 in.
		Red harvester ants start out from the nest on main routes on which they have left a scent; where these routes stop they go forth individually.
		Harvester ants remove growing plants from around their nests, which causes large bare spots in lawns and fields.

	Ant Movies
		Ant colonies are eusocial, and are very much like those found in other such Hymenopterans, though the various groups of these probably developed sociality independently through convergent evolution.
		Ant communication is primarily through chemicals called pheromones, which, because most ants spend their time in direct contact with the ground, are more developed than in other Hymenopterans.
		A crushed ant will emit an alarm pheromone that in high concentration sends other ants nearby into an attack frenzy, and in lower concentration attracts them, while a few ants use what are called propaganda pheromones to confuse their enemies.

	Red harvester ant - Wikipedia, the free encyclopedia
		Red Harvester Ants can be aggressive and have a painful sting that spreads through the lymph nodes, sometimes causing reactions, especially in those allergic to their venom.
		Their decline has affected many native species, as the red harvester ant is a chief source of food for certain animals such as the Texas horned lizard.

	Urban IPM: Insects: Ants: Harvester Ants
		Harvester ants are so called due to their tendency to collect and harvest seeds. There are 22 species found in the United States. Workers are between ¼ and ½ inch (4.7-11.5 mm) in length.
		Swarmers are seen in the summer. Young queens mate with ants from nearby colonies in a mating flight.
		Due to their large structure and surrounding defoliation, nests are easy to locate. During the hottest part of the day, worker ants rest inside the nest. Nests need to be treated with a pesticide bait suitable for harvester ants.

	Red Imported Fire Ant Management Guidelines--UC IPM
		Red imported fire ant workers are variable in size (1/16 to 1/5 inch long) and dark reddish brown.
		Nests of the native southern fire ant, for instance, are usually irregular and consist of scattered soil with multiple obscure entrances.
		Because red imported fire ants often build their nests in turfgrass areas in California, frequently the mounds have been mowed and are nearly flat, appearing as soft, loose dirt that obscures the grass and looks like a bald spot in the turf.

	RedAntsFinalDraft
		The research question is to determine how individual, dim-witted ants are able to build complex nests and maintain their colonies, using a new generation of ants each year, for the twenty-year life span of their colonies.
		The results of their studies were surprising; by observing individual ants and ant colonies over years, the researchers found that although the nests are very similar, the individual ants are not specialized and the colonies do not have leaders.
		She concluded that ants do not have inherited abilities or task orientations, but rather an ability to switch tasks and be flexible, based on their interactive patterns.

	Imported Fire Ant - FAQ

		Imported fire ants are often the worst where native ants have been disrupted by soil disturbances that accompany home and road construction, or exterminated by broad spectrum pesticides.
		Ant pieces are tossed on ant trash piles or middens and adult flies emerge from pupae about 45 days after the original attack.

		She measures the area and the paths each colony uses for gathering seeds; she counts the ants; she marks them with distinctive colors, to figure out whether (for example) the middens ever become foragers.
		If a small number of the patrolling ants are plucked up and spirited away, the colony will continue as before; but there is a crucial number that causes the whole colony to shut down.
		Strange ants plopped down in the middle of the colony may be ignored, unless they are from nearby colonies.
