Larvae are up to 30mm long, they feed on plant roots and can remain until next spring in the soil.
The adults appear early in the spring, they grow up to 8–12 millimetres (0.31–0.47in) and can mostly be encountered from May through July. They are considered an insect pest that do not just feed on pollen, but rode the floral organs, especially damaging light in color buds and flowers.
Their colour is black, more or less bronzed. Most of the specimens show six white spots in two longitudinal rows on the pronotum and many others on the elytra. They are completely covered with white pubescence (easily visible in profile). Older specimens usually have no hairs, as they are rubbed off with time.
Cetonia aurata, called the rose chafer or the green rose chafer, is a beetle, 20 millimetres long, that has a metallic structurally coloured green and a distinct V-shaped scutellum. The scutellum is the small V-shaped area between the wing cases; it may show several small, irregular, white lines and marks. The underside of the beetle has a coppery colour, and its upper side is sometimes bronze, copper, violet, blue/black, or grey.
The Colorado potato beetle is a beetle known for being a major pest of potato crops. It is about 10 mm long, with a bright yellow/orange body and five bold brown stripes along the length of each of its elytra. Native to the Rocky Mountains, it spread rapidly in potato crops across America and then Europe from 1859 onwards.
The telephone-pole beetle is a beetle native to the eastern United States and the only known living representative of the otherwise extinct family Micromalthidae. Larvae of the beetle live in decaying wood and can be pests to wooden structures, lending them their common name, the 'telephone-pole beetle.'
The common cockchafer, also colloquially known as the Maybug, Maybeetle, or doodlebug, is a species of scarab beetle belonging to the genus Melolontha. It is native to Europe, and it is one of several closely-related and morphologically similar species of Melolontha called cockchafers, alongside Melolontha hippocastani.
The deathwatch beetle is a species of woodboring beetle that sometimes infests the structural timbers of old buildings. The adult beetle is brown and measures on average 7 mm (0.3 in) long. Eggs are laid in dark crevices in old wood inside buildings, trees, and inside tunnels left behind by previous larvae. The larvae bore into the timber, feeding for up to ten years before pupating, and later emerging from the wood as adult beetles. Timber that has been damp and is affected by fungal decay is soft enough for the larvae to chew through. They obtain nourishment by using enzymes present in their gut to digest the cellulose and hemicellulose in the wood.
The varied carpet beetle is a 3 mm-long beetle belonging to the family Dermestidae, positioned in subgenus Nathrenus. They are a common species, often considered a pest of domestic houses and, particularly, natural history museums, where the larvae may damage natural fibers and can damage carpets, furniture, clothing, and insect collections. A. verbasci was also the first insect to be shown to have an annual behavioral rhythm and to date remains a classic example of circannual cycles in animals.
The noble chafer is a species of beetles belonging to the family Scarabaeidae, subfamily Cetoniinae.
Trichius fasciatus, the Eurasian bee beetle, is a beetle species belonging to the family Scarabaeidae, subfamily Cetoniinae.
Ulmus changii, occasionally known as the Hangzhou elm, is a small deciduous tree found across much of China in forests at elevations of up to 1800 m. Owing to its increasing scarcity, U. changii was added to the Hainan Province Protected Plants List in 2006.
Cotinis nitida, commonly known as the green June beetle, June bug or June beetle, is a beetle of the family Scarabaeidae. It is found in the eastern United States and Canada, where it is most abundant in the South. It is sometimes confused with the related southwestern species figeater beetle Cotinis mutabilis, which is less destructive.
The American Elm cultivar Ulmus americana 'Littleford' was cloned from a tree in Hinsdale, Illinois, circa 1915 by Littleford Nurseries of Downers Grove, Illinois, and first released in 1927. It was marketed in the 1930s by nearby Hinsdale Nurseries, successor to Littleford Nurseries, as 'Littlefordii'. In their 1925 catalogue Littleford Nurseries had written of their selection: "The growing of the American elm is a specialty with us; we consider it the leading shade and ornamental tree. Our trees are a selected strain of the V-shaped type, a stock of 15 to 20 thousand, all 2 ins. and up in size, transplanted twice and in splendid vigor for planting".
Dolycoris baccarum, the sloe bug or hairy shieldbug, is a species of shield bug in the family Pentatomidae.
Clytus arietis, the wasp beetle, is a wasp-mimicking longhorn beetle species in the genus Clytus.
Anthrenus (Anthrenus) scrophulariae, also known as the common carpet beetle or buffalo carpet beetle, is a species of beetle originally found in Europe, the Middle East and the Nearctic, which has now spread to most of the world. Adult beetles feed on pollen and nectar, but the larvae feed on animal fibres and can be damaging pests to carpets, fabrics and museum specimens.
Stenopterus rufus is a beetle species of round-necked longhorns belonging to the family Cerambycidae, subfamily Cerambycinae.
Stenurella melanura is a flower longhorn beetle species of the family Cerambycidae, subfamily Lepturinae.
Anoplotrupes stercorosus, the dor beetle, is a species of earth-boring dung beetle belonging to the family Geotrupidae, subfamily Geotrupinae.
Hoplia argentea is a species of scarabaeid beetle belonging to the subfamily Melolonthinae.
Chlorophorus varius, the grape wood borer, is a species of beetle in the family Cerambycidae.
Phyllopertha horticola, the garden chafer or garden foliage beetle, is a beetle from the family Scarabaeidae. Phyllopertha horticola was described by Carl Linnaeus in his landmark 1758 10th edition of Systema Naturae.
