Book Description

Excerpt from Journal of the New York Entomological Society, Vol. 25: Devoted to Entomology in General; 1917 In the literature dealing with Aquatic Hemiptera, we are informed that there are some ten or eleven families of the higher Heteroptera that dwell in or upon the water, where they maintain themselves by preying upon other living forms. An examination of the external structure of the majority of them substantiates this view. For whether we examine the slender Hydrometra that stalks its prey upon the water, or the Naucorid that lies in wait in the tangled vegetation of the pool, we find a sharp beak, and, in the latter case, rapacious forelegs. These are the two extremes to be sure. The foreleg of Hydrometra is but slightly modified if at all, but the beak is sharp and the stylets, though flexible, are strongly and retrorsely barbed-; while the foreleg of the Naucorid is greatly modified into a most efficient grasping device (Plate II, figs. 3 and 6).
