I performed about 2,000 measurements of head widths and leg lenghts in order to provide a large enough sample size for data analysis purposes. I completed a thesis that concluded that time of day of forage directly correlates with ant body size. Overall, larger species of ants forage at night, and larger members of a species forage during the day.
My thesis can be found by following the link below.
