Gelastocoridae
The Gelastocoridae (toad bugs) is a family of about 100 species of insects in the suborder Heteroptera. They are reminiscent of toads both in the warty appearance and hopping movements of some species.
==Biology==
Gelastocoridae are riparian insects, generally found at the margins of streams and ponds, where they are predators of small insects. Gelastocoridae catch their prey by leaping on top of them and grasping them with their modified front legs.〔Borror DJ, Tripplehorn CA, Johnson NF (1989) An Introduction to the Study of Insects, 6th edition. Harcourt Brace College Publishers. New York. pg 213〕 Members of the family are found throughout the world, but their highest diversity is in the tropics.〔Resh VH, Cardé RT (2003) Encyclopedia of Insects. Academic Press, Amsterdam, pg 956〕〔(【引用サイトリンク】url=http://www.bedbugguide.com/how-to-get-rid-of-bed-bugs-control-the-spread/ )〕
Nymphs of many species cover themselves with a layer of sand grains. Apart from the no doubt considerable physical protection that the armour affords them, the layer of sand renders them effectively invisible on the ground unless they move at the wrong moment.
