Phimodera Humeralis
''Phimodera humeralis'' is a small mostly European shield-backed bug in the tribe Phimoderini. Although occasionally seen in northern Europe, its primary range is southern Europe. Description The imago stage measures and ranges in colour from sandy ochre to pale brown. ''Phimodera humeralis'' is found in sparsely vegetated dune terrain on heaths and sandy hills, living on and especially in the sand around ''Carex arenaria ''Carex arenaria'', or sand sedge, is a species of perennial sedge of the genus ''Carex'' which is commonly found growing in dunes and other sandy habitats, as the species epithet suggests (Latin , "sandy"). It grows by long stolons under the so ...'', a 10–40 cm-high grass. ''P. humeralis'' is difficult to see, as from a distance they look like small light gray stones. Adult (imago) ''P. humeralis'' hibernate through winter and mate in the spring. The mating takes about 10–15 minutes. The nymphs are and are usually found on the ''C. arenar ...

Johan Wilhelm Dalman
Johan Wilhelm Dalman (November 4, 1787 in Hinseberg, Västmanland – July 11, 1828 in Stockholm) was a Swedish physician and a naturalist. He first studied at Christiansfeld in Schleswig-Holstein then at the University of Lund and the University of Uppsala. He was mainly interested in entomology and botany. He received his degree in 1816 then his doctorate in 1817 from the University of Uppsala. Dalman became librarian of the Royal Swedish Academy of Sciences, a member of the Academy in 1821, then director of the zoological garden, then demonstrator in botany at the Karolinska Institutet of Stockholm. Dalman's main interest lay in entomology and botany, but he also became involved in the systematics and taxonomy of trilobites. In 1771 Johann Ernst Immanuel Walch (1725-1778) first used the term trilobite. Researchers had tried to link trilobites to extant groups such as chitons and various arthropods. Before Walch’s work this had led to great confusion. By 1820 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Scutelleridae
Scutelleridae is a family of true bugs. They are commonly known as jewel bugs or metallic shield bugs due to their often brilliant coloration. They are also known as shield-backed bugs due to the enlargement of the thoracic scutellum into a continuous shield over the abdomen and wings. This latter characteristic distinguishes them from most other families within Heteroptera, and may lead to misidentification as a beetle rather than a bug. These insects feed on plant juices from a variety of different species, including some commercial crops. Closely related to stink bugs, they may also produce an offensive odour when disturbed. There are around 450 species worldwide. Description Jewel bugs are small to medium-sized oval-shaped bugs with a body length averaging at . They can easily be distinguished from stink bugs (Pentatomidae) because the shield-like enlarged last section of their thorax (known as the scutellum, Latin for "little shield") completely covers the abdomen and the w ...

Imago
In biology, the imago (Latin for "image") is the last stage an insect attains during its metamorphosis, its process of growth and development; it is also called the imaginal stage, the stage in which the insect attains maturity. It follows the final ecdysis of the immature instars.Carpenter, Geo. H., The Life-Story of Insects. Cambridge University Press 1913. May be downloaded from: https://www.gutenberg.org/ebooks/16410 or https://archive.org/details/thelifestoryofin16410gut In a member of the Ametabola or Hemimetabola, in which metamorphosis is "incomplete", the final ecdysis follows the last immature or '' nymphal'' stage. In members of the Holometabola, in which there is a pupal stage, the final ecdysis follows emergence from the pupa, after which the metamorphosis is complete, although there is a prolonged period of maturation in some species. The imago is the only stage during which the insect is sexually mature and, if it is a winged species, has functional wings. The i ...

Insects Described In 1823
Insects (from Latin ') are pancrustacean hexapod invertebrates of the class Insecta. They are the largest group within the arthropod phylum. Insects have a chitinous exoskeleton, a three-part body (head, thorax and abdomen), three pairs of jointed legs, compound eyes and one pair of antennae. Their blood is not totally contained in vessels; some circulates in an open cavity known as the haemocoel. Insects are the most diverse group of animals; they include more than a million described species and represent more than half of all known living organisms. The total number of extant species is estimated at between six and ten million; In: potentially over 90% of the animal life forms on Earth are insects. Insects may be found in nearly all environments, although only a small number of species reside in the oceans, which are dominated by another arthropod group, crustaceans, which recent research has indicated insects are nested within. Nearly all insects hatch from eggs. Insect ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
