The small tortoiseshell is a colourful Eurasian butterfly in the family Nymphalidae. Adults feed on nectar and may hibernate over winter; in warmer climates they may have two broods in a season. While the dorsal surface of the wings is vividly marked, the ventral surface is drab, providing camouflage. Eggs are laid on the common nettle, on which the larvae feed.
Urtica dioica, often known as common nettle, stinging nettle or nettle leaf, or just a nettle or stinger, is a herbaceous perennial flowering plant in the family Urticaceae. Originally native to Europe, much of temperate Asia and western North Africa, it is now found worldwide, including New Zealand and North America. The species is divided into six subspecies, five of which have many hollow stinging hairs called trichomes on the leaves and stems, which act like hypodermic needles, injecting histamine and other chemicals that produce a stinging sensation upon contact. The plant has a long history of use as a source for traditional medicine, food, tea, and textile raw material in ancient societies such as the Saxons.
Urtica is a genus of flowering plants in the family Urticaceae. Many species have stinging hairs and may be called nettles or stinging nettles, although the latter name applies particularly to Urtica dioica.
Lamium (dead-nettles) is a genus of about 40–50 species of flowering plants in the family Lamiaceae, of which it is the type genus. They are all herbaceous plants native to Europe, Asia, and northern Africa, but several have become very successful weeds of crop fields and are now widely naturalised across much of the temperate world.
Lamium purpureum, known as red dead-nettle, purple dead-nettle, or purple archangel, is a herbaceous flowering plant native to Europe and Asia.
Urticating hairs or urticating bristles are one of the primary defense mechanisms used by numerous plants, almost all New World tarantulas, and various lepidopteran caterpillars. Urtica is Latin for "nettle", and bristles that urticate are characteristic of this type of plant, and many other plants in several families. This term also refers to certain types of barbed bristles that cover the dorsal and posterior surface of a tarantula's or caterpillar's abdomen. Many tarantula species eject bristles from their abdomens, directing them toward potential attackers. These bristles can embed themselves in the other animal's skin or eyes, causing physical irritation, usually to great discomfort. The term urticating hairs is a misnomer, as technically only mammals possess true hairs.
Urtica ferox or ongaonga, also known as tree nettle, taraonga, taraongaonga, оr okaoka. is a nettle that is endemic to New Zealand. Unlike other herbaceous species in the genus Urtica, ongaonga is a large woody shrub that can grow to a height of 3 m (9.8 ft), with the base of the stem reaching 12 cm (4.7 in) in thickness. It has large spines that can result in a painful sting that lasts several days.
Lamium album, commonly called white nettle or white dead-nettle, is a flowering plant in the family Lamiaceae. It is native throughout Europe and Asia, growing in a variety of habitats from open grassland to woodland, generally on moist, fertile soils.
Pilea pumila, commonly known as clearweed, is an edible herbaceous plant in the nettle family (Urticaceae). It is native to Asia and eastern North America, where it is broadly distributed.
Urtica urens, commonly known as annual nettle, dwarf nettle, small nettle, dog nettle, or burning nettle, is a herbaceous annual flowering plant species in the nettle family Urticaceae. It is native to Eurasia and it can be found in North America, New Zealand and South Africa as an introduced species. It is reputed to sting more strongly than common nettle.
Urtica incisa, commonly called scrub nettle, stinging nettle, and tall nettle, is an upright perennial herb native to streams and rainforest of eastern and southern Australia, from the north–east southwards through the east, of Queensland and New South Wales, then across the south, through Victoria, Tasmania, south-eastern South Australia and parts of southern Western Australia. Also widespread in the North and South Island of New Zealand.
Aglais milberti, the fire-rim tortoiseshell or Milbert's tortoiseshell, is considered the only species of the proposed Aglais genus that occurs in North America.
Urtica dioica subsp. galeopsifolia, the fen nettle or stingless nettle, is a herbaceous perennial plant found in Europe. It is considered to be either a subspecies of stinging nettle, or a species in its own right: Urtica galeopsifolia.
3,4-Divanillyltetrahydrofuran is a lignan found in an Urtica dioica subspecies. This same compound may also be found in other lignan-containing plant sources such as Linum usitatissimum.
Urtica massaica is a species of flowering plant in the Urticaceae known by many English names, including Maasai stinging nettle and forest nettle. It is native to Africa, where it can be found in Congo, Burundi, Rwanda, Kenya, Uganda, and Tanzania.
A stinging plant or a plant with stinging hairs is a plant with hairs (trichomes) on its leaves or stems that are capable of injecting substances that cause pain or irritation.
Urtica dioica subsp. gracilis, the California nettle or American stinging nettle, is a herbaceous perennial plant native to most of the United States and Canada. It is either considered to be a subspecies of stinging nettle, or a species in its own right: Urtica gracilis.
Urtica pilulifera, also known as the Roman nettle, is a herbaceous annual flowering plant in the family Urticaceae.
Nettle tree or tree nettle can refer to:
