Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs (because they fly to lights in large numbers), alligator ticks, or alligator fleas (in Florida). They are the largest insects in the order Hemiptera. [1]
The largest of the earwigs is the Saint Helena earwig (Labidura herculeana), which is up to 8.4 cm (3.3 in) in length. There are no recent records of this species and it is generally considered extinct. [12] The largest certainly living species is the Australian giant earwig (Titanolabis colossea), which is about 5 cm (2.0 in) long. [7]
The giant cicada is the only species of the genus Quesada found in North America. The species feeds off of a wide variety of plant families. The species feeds off of a wide variety of plant families. As an endothermic species, it has the ability to live in a wide range of environments. [ 5 ]
The insects eat the foliage of these plants, and use camouflage to blend into the woody parts of their habitat. [14] Unusually large groups of this species were observed in June 1981 and June 2000 in Texas, though an exact cause of these groupings has not been determined.
[11] [16] Like most insects, communication within the species is a mix of chemoreception, sight, and mechanical perception. Experiments on D. hercules have shown that a male placed in the vicinity of a female will immediately orient towards her and seek her out, suggesting chemical communication through strong sexual pheromones.
Lethocerus sp. with wings open. Unlike giant water bugs in the subfamily Belostomatinae, females do not lay the eggs on the backs of males. [4] Instead, after copulation (often multiple sessions [5]) the eggs are laid on emergent vegetation (rarely on man-made structures) high enough above the waterline that the eggs will not be permanently submerged.
Abedus is a genus of giant water bugs (family Belostomatidae) found in freshwater habitats in southern United States, Mexico and Central America. [1] [2] Sometimes called ferocious water bugs, [3] these brown insects typically are between 2.3 and 4 cm (0.9–1.6 in) long, [1] [4] although A. immaculatus only is about 1.3–1.4 cm (0.51–0.55 in), making it the smallest North American ...
Arilus cristatus, also known as the North American wheel bug or simply wheel bug, [1] is a species of large assassin bug in the family Reduviidae and the only species of wheel bug found in the United States. [2] [3] It is one of the largest terrestrial true bugs in North America, reaching up to 1.5 inches (38 mm) in length in its adult stage. [4]
