Rhopalus subrufus is a species of scentless plant bugs belonging to the family Rhopalidae, subfamily Rhopalinae. Length is about 7 millimetres (0.28 in). It can be distinguished for its membranous forewings and the connexivum with dark and light stripes. It mainly feeds on Hypericum species, but also on many other plants. It is found in most of Europe.
The marsh rhopalid is a striking organism with a shield-shaped exoskeleton, marked by a distinctive pattern of spots and lines that serve as a form of camouflage among the foliage where it resides. Primarily herbivorous, this species has a rostrum that pierces plant tissues to access sap, a feeding behavior that begins at a very young stage and continues throughout its life cycle. The adaptability in its diet reflects an evolutionary specialization to survive in various ecological niches.
Stictopleurus punctatonervosus can reach a length of 0.26–0.35 in. These bugs have a regularly punctuated pronotum, a banded connexivum and a rounded tip of the scutellum. The body is gray-brown to black, while the abdomen is often greenish. In the anterior margin of the pronotum there are quite difficult to discern dark marks similar to two half circles or to reading glasses.
With a life cycle including eggs that overwinter, knapweed rhopalid transforms from flightless nymphs to winged adults, capable of flight. Feasting mainly on plant juices, these insects harbor symbiotic bacteria within specialized cells known as bacteriocytes, which aid in nutrient absorption from their diet. They exhibit various shades and patterns across their exoskeleton, which acts as effective camouflage amidst vegetation.
With an elongated body elegantly adorned in mottled brown and tan, stictopleurus minutus thrives in a variety of environments, from grasslands to human-inhabited areas. This adept insect feeds primarily on plant juices, extracted with piercing mouthparts designed to penetrate stem and leaf tissues. Remarkably, stictopleurus minutus can emit a pungent odor as a defense mechanism when threatened, warding off would-be predators with a display of chemical ingenuity.
The female red-Shouldered Bug( Jadera haematoloma), is known for the red eyes and red "shoulders". This bug lives throughout the United States and is usually considered a nuisance pest indoors. They do not bite people but can leave fecal matter which may stain walls, upholstery, and furniture.
The eastern Boxelder Bug (Boisea trivittata) pierces and feeds on maple seeds. They are not generally considered pests unless they invade homes or destroy fruit in the process. If they do invade homes, their excrement can stain the upholstery. They are also known as the boxelder bug.
Western honey bee（Apis mellifera） is the most common species of honeybee in the world. Among the first domesticated insects, its cultural and economic impact on humanity has been vast and far-reaching, providing honey, wax and its services as a pollinator. Western honey bee faces challenges worldwide, such as colony collapse disorder, and populations are thought to be decreasing.
The monarch butterfly (Danaus plexippus) is the most recognizable butterfly in North America. It is best known for its appearance, but should be better known for the fact that it has a 3000-mile migration that takes the butterfly 4 generations to complete. Their diet is also a natural deterrent for predators, as they eat milkweed, a poison that induces vomiting.
The japanese rhinoceros beetle (Trypoxylus dichotomus) is a massive beetle about the size of the palm of a hand. It's distinguished by its long Y-shaped horn, which it uses to fight other males with. It's a nocturnal bug that feeds on sap and sweet fruits. This species is sometimes kept as a pet due to its unique appearance and simple care requirements.
The silken threads produced by silkworm during its larval stage have been highly coveted for millennia, manifesting as a luxurious fabric in human society. Remarkably, this creature has a singular diet, feeding exclusively on the leaves of its primary host plant from which it extracts the necessary nutrients to facilitate its transition into a non-feeding, winged adult.
Menelaus blue morpho (Morpho menelaus) is a gorgeous butterfly with large, royal blue wings. Linnaeus named the genus Morpho the Aphrodite-Ancient Greek goddess of love and beauty for its extreme beauty. It is native to tropical rainforests. Though many butterfly gardens now cultivate them in captivity, there are still many people who never get a chance to see them.
While the atlas moth (Attacus atlas) can't tell you where to find your country on the map, it does earn its name through other means. It is one of the largest moths in the world, with a wingspan that is far larger than its body, creating an abnormal comparison. In India, their silk is gathered in a non-commercial capacity and is considered to be more durable than the domestic silkworm.
Both sexes reach about 5 mm in body length. Females and immatures of both sexes are brown but have color patterns by which they can be distinguished from related species. Also, the males dance to attract females.
Often confused for the ladybug, multicolored asian ladybeetle (Harmonia axyridis) is a separate species that, unlike the ladybug, is a household pest. It is considered particularly annoying for its habit of returning to places from which it is removed. One of the most variable species in the world, there are many different colors and patterns multicolored asian ladybeetle may display, making identification potentially difficult.
