Adult froghoppers jump from plant to plant; some species can jump up to 70 cm (28 in) vertically: a more impressive performance relative to body weight than fleas. The froghopper can accelerate at 4,000 m/s 2 (13,000 ft/s 2 ) over 2 mm (0.079 in) as it jumps (experiencing over 400 gs of acceleration). [ 8 ]
They are sometimes called tube-forming spittle-bugs as the nymphs form a calcareous tube within which they live. These bugs are mainly found in the Old World tropics. The adults of many genera have a long, free and spine-like process originating from the scutellum and thus superficially similar to the tree-hoppers, Membracidae.
Traditionally, most of the superfamily Cercopoidea was considered a single family, the Cercopidae, but this family has been split into three families for many years now: the Aphrophoridae, Cercopidae, and Clastopteridae.
Cercopidae are the largest family of Cercopoidea, a xylem-feeding insect group, commonly called froghoppers. [2] They belong to the hemipteran suborder Auchenorrhyncha.A 2023 phylogenetic study of the family suggested the elevation of the New World subfamily Ischnorhininae to full family status as Ischnorhinidae, leaving a monophyletic Old World Cercopinae.
There are only a few species of spiders in the U.S. that can bite humans. “The truth is that most spiders are too small to bite us, including those adorable jumping spiders,” Jody Gangloff ...
Ranatra is a genus of slender predatory insects of the family Nepidae, known as water scorpions or water stick-insects. [1] There are more than 140 Ranatra species found in freshwater habitats around the world, both in warm and temperate regions, with the highest diversity in South America (almost 50 species) and Asia (about 30 species, reviewed in 1972 [2]).
Nepidae is a family of exclusively aquatic Heteropteran insects in the order Hemiptera. [1] They are commonly called water scorpions for their superficial resemblance to scorpions, due to their raptorial forelegs and the presence of a long slender process at the posterior end of the abdomen, resembling a tail. [2]
They typically spit at prey at a mean angle of about 74° from the horizontal but can still aim accurately when spitting at angles between 45° and 110°. [ 10 ] When an archerfish selects its prey, it rotates its eye so that the image of the prey falls on a particular portion of the eye in the ventral temporal periphery of the retina , [ 11 ...
