sentences:  The adaptive foraging hypothesis has been criticized because males are considered poor meals when compared to crickets; however, recent findings discovered "Hogna helluo" males have nutrients crickets lack, including various proteins and lipids.In "H. helluo", females have a higher protein diet when cannibalizing males than when consuming only house crickets.Further studies show that "Argiope keyserlingi" females with high-protein/low-lipid diets resulting from sexual cannibalism may produce eggs of greater egg energy density (yolk investment).
