Abstract

Hooking Up in Water Striders The male water strider Rheumatobates rileyi has an extensively modified antenna that is used for forced copulations with females. Khila et al. (p. 585 ) describe several microscopic antenna attributes that make the antenna fit perfectly with the female head when the male grasps the female. The features depend upon the expression of the gene distal-less ( dll ) during antenna development. Reducing the expression of dll compromised male grasping traits, while female antennae were unaffected.
