One of their characteristics is being able to choose a certain diet (not that they dont already swarm any figure of food left out) that they might need.

If its winter they might choose a complex moolah for energy, or a more(prenominal) convenient sheath of food that is easier to carry to the nest. If its warmer weather they can choose more of a protein type of food. (Stephens, D. W. and Krebs) Foragers of the ant tend to return to antecedently rewarding sites to search for food. The search tactic depends on the type of food contracted during the previous foraging trip: a carbohydrate-stimulated local search is of the greater duration and is more spatially concentrated in the vicinity of the site of the prior note than a protein-stimulated local search. (Fourcassie&Traniello) I wanted to filtrate something different from peanut butter and jelly, a different outset of protein and carbohydrate. I decided to use broken up frankfurter portions and saltine crackers.
First, the hotdogs cave in not only protein, but they also have lipids and the saltine crackers have a higher concentrate of calories per grand than normal breads do, as well as salt. The type of ant that I chose to do this project on the is the imported fervency ant (Solenopsis invicta.) The Fire Ants (Solenopsis invicta) habitats are in fields, woodlands, and open areas, in dry to moist soil. Their Range is Florida and Gulf states to Pacific Coast, coupling to British Columbia.(...
