Sphaeroderma testaceum, the artichoke beetle, is a species of flea beetles in the family Chrysomelidae. [1] [2]
This species is present in most of Europe, [3] North Africa and Israel. [4] It is adventive in Northern America (Atlantic Canada), [5] [6]
These beetles mainly inhabit wasteland, woodland, roadsides and other areas where host plants occur. [7]
Sphaeroderma testaceum can reach a size of 3.5–4 millimetres (0.14–0.16 in). [5] These tiny beetles have a wide head, large eyes and the filiform antennae are close together between the eyes. Elytra are convex and slightly elongate and hind femora are rather enlarged. The pronotum shows coarse puncturation basally, prominent anterior corners, a well defined basal groove and two lateral notches. [8] Elytra and pronotum are shiny light brown-orange. [4]
This species is very similar to Sphaeroderma rubidum (Graëlls, 1853). It can be distinguished from the previous one on the basis of a smaller size and quadrate elytra, [8] but especially with a close study of the genitalia.
Adults can be found from May/June to September. Pupation occurs in the spring and new adults may be seen from May. Overwintering occurs as 3rd (final) instar larvae, sometimes as imago. [9]
Both larvae and adults feed on leaves, especially on various species of Thistle ( Carduus , Carlina , Cirsium , Onopordum and Cynara species), on Common Knapweed ( Centaurea nigra ), on Serratula species and on Cirsium arvense (in Canada). [6] [7]
The tansy beetle is a species of leaf beetle. The common name derives from its main foodplant, Tansy, but it can also use other wetland plants such as Gypsywort and Water Mint. It measures 7.7–10.5 mm in length and has a characteristic bright metallic green colouration, with pitted elytra and a coppery tinge. In addition to the nominotypical subspecies, which repeats the specific name, C. graminis graminis, there are five further distinct subspecies of Tansy beetle, which, collectively, have a Palearctic distribution, although in the majority of countries where it is found the species is declining. In the United Kingdom it is designated as 'Nationally Rare'. The stronghold population here is located along the banks of the river Ouse in York, North Yorkshire. Other, small, fenland populations exist at Woodwalton Fen and at Welney Wildfowl and Wetlands Trust (WWT) reserve.
The bloody-nosed beetle, also called blood spewer or blood-spewing beetle, is a leaf beetle native to Europe.
The scarlet lily beetle, red lily beetle, or lily leaf beetle, is a leaf beetle that eats the leaves, stem, buds, and flowers, of lilies, fritillaries and other members of the family Liliaceae. It lays its eggs most often on Lilium and Fritillaria species. In the absence of Lilium and Fritillaria species, there are fewer eggs laid and the survival rate of eggs and larvae is reduced. It is now a pest in most temperate climates where lilies are cultivated.
Chrysolopus spectabilis is a species of weevil found in south-eastern Australia. It was discovered during James Cook's first voyage, and became one of the first insects to be described from Australia. The weevil measures up to 25 mm (1.0 in) long and includes distinctive metallic green and black scales. It is found only on 28 species of the plant genus Acacia.
The Cassidinae are a subfamily of the leaf beetles, or Chrysomelidae. The antennae arise close to each other and some members have the pronotal and elytral edges extended to the side and covering the legs so as to give them the common name of tortoise beetles. Some members, such as in the tribe Hispini, are notable for the spiny outgrowths to the pronotum and elytra.
Chrysolina cerealis, the rainbow leaf beetle or Snowdon beetle, is a beetle belonging to the family Chrysomelidae.
Larinus is a genus of true weevils, comprising about 180 species, mostly in the Palaearctic region with some species introduced to North America. Turkey appears to have a significant diversity of the group, with more than 50 species recorded in the eastern part of the country.
Oiceoptoma noveboracense is a member of the family Silphidae, or carrion beetles, which feed on decaying organic matter such as dead animals. Its common name is the margined carrion beetle, from the orange-red margins on the pronotum, which are helpful when identifying this species. The larva is typically light brown to red and also has vertical ridges on its thorax like the adult. This diurnal beetle can be found mainly in the spring into the fall, and it has a strong preference towards a deciduous forest habitat. The primary forensic importance of this beetle is its ability to use the succession of insect fauna to provide confirmation of postmortem intervals.
Galeruca tanaceti is a species of leaf beetle found in the Palearctic realm, and is the type species of the genus Galeruca. It feeds on various plants in both its adult and larval stages. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Chrysomela populi is a species of broad-shouldered leaf beetle belonging to the family Chrysomelidae, subfamily Chrysomelinae.
Lilioceris merdigera is a species of beetle belonging to the family Chrysomelidae, subfamily Criocerinae.
Galerucella lineola is a species of leaf beetle in the family Chrysomelidae.
Pyropterus nigroruber is a species of net-winged beetles belonging to the family Lycidae.
Alurnus ornatus is a species of beetle in the family Chrysomelidae that can grow 19–27 millimeters in length. It is found in Colombia, Costa Rica, Nicaragua, and Panamá.
Sphaeroderma is a large genus of flea beetles in the family Chrysomelidae, with some 250 species from the Old World.
Zygogramma suturalis, commonly known as the ragweed leaf beetle, is a species of leaf beetle belonging to the genus Zygogramma. Native to North America, it has been introduced into Russia and China for the biological pest control of ragweed.
Anisodactylus binotatus is a species of ground beetle native to Europe. It was discovered as being introduced to Canterbury, New Zealand in 1938. Anisodactylus binotatus is a species of Carabidae, also known as the ground beetle family. Although this species of beetle has no official recorded common names, literature from England refers to it as the common shortspur beetle.
Lamprolina is an Australian genus of leaf beetles (Chrysomelidae) found in Victoria, New South Wales, and Queensland.
Heliocopris bucephalus, commonly known as Elephant dung beetle, is a species of dung beetle found in India, Sri Lanka, Bangladesh, Myanmar, Malay Peninsula, Java, Vietnam, Laos, and Cambodia.
Illeis cincta, is a species of lady beetle native to India, Sri Lanka and Indonesia.
