Cetonia aurata, called the rose chafer or the green rose chafer, is a beetle, 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. Cetonia aurata should not be confused with the North American rose chafer, Macrodactylus subspinosus, or with the rarely seen noble chafer, Gnorimus nobilis, which is very similar to the rose chafer.

Cetonia is a genus of beetles in family Scarabaeidae. One of the most familiar species is the rose chafer (C. aurata).

Dichelonyx backii, known generally as the green pine chafer or green rose chafer, is a species of scarab beetle in the family Scarabaeidae.

Macrodactylus uniformis, the western rose chafer, is a species of May beetle or junebug in the family Scarabaeidae. It is found in Central America and North America.

Macrodactylus subspinosus is a North American beetle of the family Scarabaeidae. The members of this genus are known as "rose chafers", not to be confused with the European "rose chafer", Cetonia aurata. M. subspinosus occurs from Eastern Canada to Colorado and is considered a pest of many crops and flowers. It is given its common name of rose chafer because it eats the leaves of roses, although it also feeds on many other plants.

One way to identify Cetonia aurata is to look at its scutellum; on the noble chafer the scutellum is an equilateral triangle, but on the rose chafer it is an isosceles triangle.

Strigoderma arbicola, known generally as sand chafer, is a species of shining leaf chafer in the family of beetles known as Scarabaeidae. Other common names include the spring rose beetle, false Japanese beetle, and rose chafer.

2,652 insect species/subspecies are recorded from Rhodes. Commonly seen insects in Rhodes are the sail swallowtail, the scarlet dragonfly, Cleopatra butterfly, European praying mantis, cicada, glow-worm, hummingbird hawk-moth, firebug, field cricket, European tree cricket, European hornet, cuckoo wasp, carpenter bee and the rose chafer.

They especially prey on hermit beetle (Osmoderma eremita) and rose chafer (Cetonia aurata). When male E. ferrugineus are attracted to a female, they release compounds that attract other males to the site. These compounds include geranyl, nerylacetone and 6-methyl-5-heptene-2-one. Attraction of males only occurs in the presence of females, ensuring increased mating opportunities.

The Guldbagge Awards (, ) is an official and annual Swedish film awards ceremony honoring achievements in the Swedish film industry. Winners are awarded a statuette depicting a rose chafer, better known by the name Guldbaggen. The awards, first presented in 1964 at the Grand Hôtel in Stockholm, are overseen by the Swedish Film Institute. It is described as the Swedish equivalent of the Academy Awards.

As a member of the order Coleoptera, the rose chafer undergoes complete metamorphosis during its development. In late May, white-bodied larvae, about long, pupate after having overwintered deep in the soil. Once they have emerged from their pupal case, adults live for 3–6 weeks, during which time they will feed on plant material and mate. Their eggs are laid in sandy soils, deep, and hatch in 1–3 weeks.

It is thus possible to distinguish between older and younger beetles, as older beetles will have fewer hairs and thus be darker in colour. Females tend to lose more hairs, especially on the thorax due to the mating process, and can also appear darker in colour. Females also tend to be more robust than the male. The eggs of the rose chafer are about 1 mm in length and are oval, white and shiny.

The leaves provide food for some animals, including Lepidoptera such as the case-bearer moth Coleophora anatipennella and North American rose chafer Macrodactylus subspinosus. The two major fungal pathogens of the sweet chestnut are the chestnut blight (Cryphonectria parasitica) and the ink disease caused by Phytophthora cambivora and Phytophthora cinnamomi. In North America as well as in Southern Europe Cryphonectria parasitica destroyed most of the chestnut population in the 20th century. With biological control, the population of the sweet chestnut is not threatened anymore by the chestnut blight and is regenerating.

Eupoecila australasiae, commonly known as the fiddler beetle or rose chafer, is a colourful green- or yellow-and-black member of the scarab beetle family from eastern Australia. The fiddler beetle was originally described by Anglo Irish naturalist Edward Donovan as Cetonia australasiae in his 1805 work An Epitome of the Natural History of the Insects of New Holland, New Zealand, New Guinea, Otaheite, and other Islands in the Indian, Southern, and Pacific Oceans. It was reclassified in and became the type species of the new genus Eupoecila by German entomologist Hermann Burmeister in 1842.Burmeister, H.C.C. 1842.

The rose chafer has a yellowish-tan coloured body that is about in length, with wings that do not completely cover the abdomen. The beetle has six long, spiny, reddish-brown legs that gradually become darker towards the end of the appendage. It has two short lamellate antennae that end in a club of flat plates and it has chewing mouthparts. Rose chafers are covered in dull yellow hairs which give the body its characteristic colour, however with age and with normal activity the hairs are worn off the head and thorax revealing a black colour.

After adult rose chafers emerge in late May to mid-June, they aggregate on leaves, buds, flowers, and fruit, in order to feed and mate. By chewing on plant tissues, the rose chafer induces the release of volatile compounds from the plant. Using their antennae, rose chafers can detect the plant compounds in the air and orient themselves in the direction of the feeding conspecific, leading to an aggregation of the beetles. Male rose chafers also orient themselves preferentially toward virgin females as opposed to mated females, though it is unknown whether they are detecting pheromones released by virgin females, or the release of plant volatiles induced by the feeding virgin females.

Insects foraging among the flowerheads The dwarf apple regenerates from bushfire by resprouting from its woody base, known as a lignotuber, or epicormic shoots. It can flower within a year of being burnt and plays an important role as a food source for nectar-eating insects after bushfire. The flowers attract birds such as the noisy miner and wattlebirds and a wide variety of insects, including honeybees, native bees, flies, moths and butterflies, and a wide array of beetles, including the rose chafer (Eupoecila australasiae), green- velvet flower chafer (Glycyphana brunnipes), the variable jewel beetle (Temognatha variabilis), the cowboy beetle (Chondropyga dorsalis), and a scarab beetle Bisallardiana gymnopleura, as well as members of the scarab genus Phyllotocus and soldier beetle genus Telephorus. The dwarf apple is a host for larvae of froghoppers, known as spittlebugs.
