Bug FAQBig-eyed Toad Bug
Gelastocoris oculatus · Order: Hemiptera · Family: Gelastocoridae
Also called: toad bug
The big-eyed toad bug lives near freshwater shores and prefers damp sand or mud, where it blends in with the substrate. Adults and nymphs catch smaller insects by jumping on them and feeding with piercing-sucking mouthparts; they lay eggs under rocks or in sand and have five nymphal stages.
