Eurydema ventralis is a shield bug of the family Pentatomidae, subfamily Pentatominae. The species was first described by Friedrich August Rudolph Kolenati in 1846.
Eurydema ventralis has a length of about 10 millimetres (0.39 in). It typically has a two-tone coloration, yellow or red with black markings. The body is flattened, the head is rounded and the cheeks are sinuous with narrow edges. When the adults come out from the last instar they are white or ivory with black spots. They slowly reach the final red coloration, at first becoming yellow, then orange and finally red. The specimens completely white and black are immature.
This species can damage the cultivations of crucifers (family Brassicaceae) and sometimes also of potatoes and cereals.
Adults overwinter, reappear in spring and attack the cabbages. In the first half of April mating begins, followed by the laying of eggs. At mid-May the nymphs hatch, reaching the maturity in June.
In summer, females lay the eggs of the second generation, this time both on crucifers and on other plants (rose, alfalfa). In July the eggs hatch and the larvae become mature in August. Adults of the second generation return on crucifers and remain there until September. At the first cold days of the autumn the adults take refuge in winter shelters.
This species can be found in most of Europe.
Pentatomidae is a family of insects belonging to the order Hemiptera, generally called shield bugs or stink bugs. Pentatomidae is the largest family in the superfamily Pentatomoidea, and contains around 900 genera and over 4700 species. As hemipterans, the pentatomids have piercing sucking mouthparts, and most are phytophagous, including several species which are severe pests on agricultural crops. However, some species, particularly in the subfamily Asopinae, are predatory and may be considered beneficial.
Anthocharis cardamines, the orange tip, is a butterfly in the family Pieridae, which contains about 1,100 species. A. cardamines is mainly found throughout Europe and temperate Asia (Palearctic) The males feature wings with a signature orange pigmentation, which is the origin of A. cardamines' common name.
Hyalophora cecropia, the cecropia moth, is North America's largest native moth. It is a member of the family Saturniidae, or giant silk moths. Females have been documented with a wingspan of five to seven inches or more. These moths can be found all across North America as far west as Washington and north into the majority of Canadian provinces. Cecropia moth larvae are most commonly found on maple trees, but they have also been found on cherry and birch trees among many others. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
Dryocampa rubicunda, the rosy maple moth, is a small North American moth in the family Saturniidae, also known as the great silk moths. It was first described by Johan Christian Fabricius in 1793. The species is known for its wooly body and pink and yellow coloration, which varies from cream or white to bright pink or yellow. Males have bushier antennae than females, which allow them to sense female pheromones for mating.
Papilio demodocus, the citrus swallowtail or Christmas butterfly, is a swallowtail butterfly which commonly occurs over the entirety of sub-Saharan Africa, including Madagascar, besides the southern Arabian Peninsula. The caterpillars feed on various native plants of especially the family Rutaceae, but have also taken to the leaves of cultivated citrus trees.
The green stink bug or green soldier bug is a stink bug of the family Pentatomidae.
Hemaris thysbe, the hummingbird clearwing, is a moth of the family Sphingidae (hawkmoths). Coloration varies between individuals, but typically the moth is olive green and burgundy on its back, and white or yellow and burgundy on the underside. Its wings are transparent with a reddish-brown border. It has light-colored legs, which combined with the lack of striping on the underside is diagnostic. Beating its wings rapidly, H. thysbe hovers to collect nectar from a variety of flowers. The combination of its appearance and its behavior commonly leads to it being confused with a hummingbird or bumblebee.
The harlequin cabbage bug, also known as calico bug, fire bug or harlequin bug, is a black stinkbug of the family Pentatomidae, brilliantly marked with red, orange, yellow and white markings. It is a major pest of cabbage and related crops in the Brassicaceae, as well as the ornamental flower cleome throughout tropical and North America, especially the warmer parts of the United States. Nymphs are active during the summer and in the tropics the bug can achieve three to six generations a year. In the northern range there is only one generation annually and the insects overwinter as adults in crop residues or field edges. Organic control involves hand-picking the insects off the plants and being especially careful to remove and destroy all the eggs, which are black-and-white striped, laid in clutches of twelve.
Papilio xuthus, the Asian swallowtail, Chinese yellow swallowtail or Xuthus swallowtail, is a yellow-colored, medium to large sized swallowtail butterfly found in northeast Asia, northern Myanmar, southern China, Taiwan, the Korean Peninsula, Japan, Siberia and the Hawaiian Islands. It was also recorded in the state of Arunachal Pradesh, India, in 2014.
Rhaphigaster nebulosa, common name mottled shieldbug, is a species of stink bug in the family Pentatomidae.
Eurydema ornata is a species of shield bug in the family Pentatomidae.
Dolycoris baccarum, the sloe bug or hairy shieldbug, is a species of shield bug in the family Pentatomidae.
Eurydema oleracea is a species of shield bug in the family Pentatomidae and is commonly known as the rape bug, the crucifer shield bug, the cabbage bug or the brassica bug.
Nezara viridula, commonly known as the southern green stink bug (USA), southern green shield bug (UK) or green vegetable bug, is a plant-feeding stink bug. Believed to have originated in Ethiopia, it can now be found across the world. Because of its preference for certain species of legumes, such as beans and soybeans, it is an economically important pest on such crops.
Bagrada hilaris is a species of shield bug known by the common names bagrada bug and painted bug. It could be mistaken for or erroneously referred to as harlequin bug. It is native to southeastern Africa. It is known elsewhere as an introduced species, including California and Arizona, where it was first reported in 2008. It is a major pest insect of Brassica oleracea crops, and related crucifers such as turnips, rape, and mustard. The adult and nymph of the species suck sap from the leaves of the plants, causing wilting, yellowing, and stunting of growth. Besides crucifers, the bugs are known on papaya, sorghum, maize, potato, cotton, caper, pearl millet, and some legumes. Large numbers of the bug congregate on the plants and cause extensive damage.
Trichopoda pennipes is a species of feather-legged fly in the dipteran family Tachinidae.
Apodiphus amygdali is a species of shield bug belonging to the family Pentatomidae, subfamily Pentatominae.
Carpocoris purpureipennis is a species of shield bug of the family Pentatomidae, subfamily Pentatominae.
Piezodorus lituratus, the gorse shield bug, is a species of Pentatomidae, a family of shield bugs.
Euthyrhynchus floridanus, the Florida predatory stink bug, is a species of carnivorous shield bug in the family Pentatomidae, the only species in the genus Euthyrhynchus. It is native to the hottest parts of the southeastern United States and is considered beneficial because it feeds on many species of pest insects. They also feed on things such as grasshoppers and other small insects. This species also hunts in a pack, with up to twelve.
