Cybister chinensis

The great diving beetle gets its name from its large size and aquatic nature, where it preys on a variety of insects and even small fish. Before diving for prey or shelter, the beetle collects air bubbles underneath its wings. The great diving beetle is often found in slow-moving bodies of fresh water.

Acilius sulcatus is a species of water beetle in family Dytiscidae.It is fairly large (14.4 – 18.2 mm), with color variation shown throughout its range. Typically it is yellow and black.

Acilius mediatus is a species of predaceous diving beetle in the family Dytiscidae. It is found in North America.

With streamlined bodies adept for underwater navigation, scarce lesser diving beetle are known for their remarkable diving skills, using their hind legs as oars to propel them through freshwater habitats. As both larvae and adults, they are formidable predators, preying on a variety of aquatic life. The development from voracious larvae to adept swimmers in adulthood showcases a complex life cycle reliant on aquatic environments.

Ilybius quadriguttatus is a species of beetle native to Europe and Near East. In Europe, it is found in Austria, Belarus, Belgium, Bulgaria, Croatia, the Czech Republic, mainland Denmark, Estonia, Finland, mainland France, Germany, Great Britain including the Isle of Man, Hungary, mainland Italy, Kaliningrad, Latvia, Liechtenstein, Lithuania, mainland Norway, Poland, Romania, Russia, Slovakia, Slovenia, mainland Spain, Sweden, Switzerland, the Netherlands, Ukraine and Yugoslavia.

Ilybius fenestratus is a species of beetle found in many countries in Europe. It was first described by Johan Christian Fabricius in 1781. The scent gland of this species of beetle is natural source for the anabolic steroid boldenone (Δ-testosterone).

The sooty mud dweller is a masterful aquatic predator, with a sleek, streamlined body adapted for a life submerged in freshwater habitats. As a larva, it exhibits a voracious appetite, feeding on other aquatic invertebrates, while adults often hunt smaller prey such as tadpoles. This species has developed a specialized method of respiration, carrying a bubble of air beneath its wing cases, which allows it to extract oxygen while submerged, embodying an elegant synthesis of form and function.

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.
