Aphelocheirus aestivalis is a Palearctic species of true bug. [1] [2] [3] It is aquatic and wingless, covered in microscopic hairs that form a physical gill when underwater. [4]
Hemiptera is an order of insects, commonly called true bugs, comprising over 80,000 species within groups such as the cicadas, aphids, planthoppers, leafhoppers, assassin bugs, bed bugs, and shield bugs. They range in size from 1 mm (0.04 in) to around 15 cm (6 in), and share a common arrangement of piercing-sucking mouthparts. The name "true bugs" is often limited to the suborder Heteroptera.
The Heteroptera are a group of about 40,000 species of insects in the order Hemiptera. They are sometimes called "true bugs", though that name more commonly refers to the Hemiptera as a whole. "Typical bugs" might be used as a more unequivocal alternative, since the heteropterans are most consistently and universally termed "bugs" among the Hemiptera. "Heteroptera" is Greek for "different wings": most species have forewings with both membranous and hardened portions ; members of the primitive sub-group Enicocephalomorpha have completely membranous wings.
Nepidae is a family of exclusively aquatic Heteropteran insects in the order Hemiptera. 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. There are 14 genera in the family, in two subfamilies, Nepinae and Ranatrinae. Members of the genus Ranatra, the most widespread and species-rich genus, are sometimes called needle bugs or water stick insects as they are slenderer than Nepa.
Notonectidae is a cosmopolitan family of aquatic insects in the order Hemiptera, commonly called backswimmers because they swim "upside down" (inverted). They are all predators and typically range from 0.5 to 1.5 cm (0.2–0.6 in) in length. They are similar in appearance to Corixidae, but can be separated by differences in their dorsal-ventral coloration, front legs, and predatory behavior. Their dorsum is convex, lightly colored without cross striations. Their front tarsi are not scoop-shaped and their hind legs are fringed for swimming. There are about 350 species in two subfamilies: Notonectinae with seven genera, and Anisopinae with four genera. Members in the former subfamily are often larger than those in the latter.
Belostomatidae is a family of freshwater hemipteran insects known as giant water bugs or colloquially as toe-biters, Indian toe-biters, electric-light bugs, alligator ticks, or alligator fleas. They are the largest insects in the order Hemiptera. There are about 170 species found in freshwater habitats worldwide, with more than 110 in the Neotropics, more than 20 in Africa, almost as many in the Nearctic, and far fewer elsewhere. These predators are typically encountered in freshwater ponds, marshes and slow-flowing streams. Most species are at least 2 cm (0.8 in) long, although smaller species, down to 0.9 cm (0.35 in), also exist. The largest are members of the genus Lethocerus, which can exceed 12 cm (4.5 in) and nearly reach the length of some of the largest beetles in the world. Giant water bugs are a popular food in parts of Asia.
Ranunculus acris is a species of flowering plant in the family Ranunculaceae, and is one of the more common buttercups across Europe and temperate Eurasia. Common names include meadow buttercup, tall buttercup, common buttercup and giant buttercup.
Adonis aestivalis, the summer pheasant's-eye, is a medicinal and ornamental plant. It is native to Europe but has been introduced elsewhere, such as the western and eastern parts of the United States. The specific epithet, aestivalis, is derived from Latin and means "pertaining to the summer". It is an annual herb.
Water treaders, the superfamily Mesovelioidea, are insects in the order Hemiptera, the true bugs. They are semiaquatic insects that live in moist and wet habitat and on wet plant matter in several types of aquatic habitat.
Sigara fallenoidea is a species of water boatman in the family Corixidae in the order Hemiptera.It was described by Hungerford and the type locality is in Canada. In Ireland Walton discovered a 'new' species of corixidae which he named Sigara pearcei. This was synonymised by Hungerford in 1950. The distribution of S. fallenoidea is therefore an extraordinary one including Canada, Ireland, Norway, Finland, Sweden, Ukraine and Russia. In Ireland, Sigara fallenoidea is found in all the large lakes on the island. There are confirmed records from Loughs Neagh, Beg and Portmore Lough; Upper and Lower Lough Erne; Lough Melvin; Loughs Ree, Derg and Key on the Shannon; and Lough Corrib.
The blueback herring or blueback shad or summer shad is an anadromous species of herring from the east coast of North America, with a range from Nova Scotia to Florida. Blueback herring form schools and are believed to migrate offshore to overwinter near the bottom.
Hebrus is a genus of velvet water bugs in the family Hebridae. There are at least 160 described species in Hebrus.
Hermatobates is a genus of wingless marine bugs placed as the sole genus in the family Hermatobatidae that are sometimes known as coral-treaders. They are quite rare and known only from coral reefs in the Indo-Pacific region. During low tide, they move over the water surface not unlike the more familiar water-striders around coral atolls and reefs and stay submerged in reef crevices during high tide.
Gerris argentatus is a Palearctic species of true bug. It is aquatic.
Gerris thoracicus is a Palearctic species of true bug.
Gerris lateralis is a Palearctic species of true bug. It is aquatic.
Velia saulii is a Palearctic species of true bug. It is aquatic.
Microvelia reticulata is a Palearctic species of true bug. It is aquatic.
