The predatory behavior of the ant lion larvae, Myrmeleon immaculatus was investigated using three different sizes of prey. Relationships between ant lion body size and pit structure, capture success and prey size, and capture time and prey size were investigated. A statistically significant relationship exists between ant lion body size and pit structure. In addition, small ant lions and large ant lions were found to differ signficantly in the sizes of prey they captured. However, the amount of time small and large ant lions spent capturing similar size prey did not differ. The results of this study indicate that although small and large ant lions invest the same amount of effort into prey capture, they do not receive equal energy return.http://deepblue.lib.umich.edu/bitstream/2027.42/54799/1/3240.pdfDescription of 3240.pdf : Access restricted to on-site users at the U-M Biological Station
