Mate guarding may function to prevent females from prematurely removing the externally attached sperm ampulla, thereby ensuring maximum insemination. This hypothesis was tested in decorated crickets, Gryllodes supplicans, by comparing ampulla retention times of females guar...

One such phytotelm habitat is the fluid-filled pitchers of species of Nepenthes, a carnivorous plant genus widely distributed in the Old World tropics. As in most histiostomatid species, males of Nepenthes-inhabiting mites seek out tritonymphal females and guard ...
