Apocynum
''Apocynum'', commonly known as dogbane or Indian hemp, is a small genus of the flowering plant family Apocynaceae. Its name comes from Ancient Greek , from "away" and "dog", referring to dogbane (''Cionura erecta''), which was used to poison dogs. The genus is native to North America, temperate Asia, and southeastern Europe. ''Apocynum'' species are used as food plants by the larvae of some Lepidoptera species, including the mouse moth and the queen butterfly. Uses ''Apocynum cannabinum'' was used as a source of fiber by Native Americans. ''Apocynum venetum'' () is used as an herbal tea in China. Dogbane contains cymarin, a cardiotonic agent formerly used to treat cardiac arrhythmia in humans. Species Almost 300 names have been proposed in the genus for species, subspecies, and forms. , only the following five species and hybrids are currently recognized, with several subspecies and varieties accepted for '' A. androsaemifolium'' and '' A. venetum'' (see their respective ...

Apocynum Venetum
''Apocynum venetum'', commonly known as sword-leaf dogbane, is a plant species in the dogbane family, poisonous but used as a source of fiber, medicine, and nectar for production of honey. Distribution and habitat ''Apocynum venetum'' is considered to be native to a wide range in northern Asia and SE Europe: Italy, Bulgaria, Romania, Ex/Yugoslavia, Turkey, Ukraine, Russia, Siberia, Central Asia, Iran, Iraq, Cyprus, Pakistan, Afghanistan, China, and Japan. It grows in swamps, wet places, and maritime sands.

Apocynaceae Genera
Apocynaceae (from ''Apocynum'', Greek for "dog-away") is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae (now known as Asclepiadoideae) is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here. Many species are tall trees found in tropical forests, but some grow in tropical dry ( xeric) environments. Also perennial herbs from temperate zones occur. Many of these plants have milky latex, and many species are poisonous if ingested, the family being rich in genera containing alkaloids and cardiac glycosides, those containing the latter often finding use as arrow poisons.

Queen Butterfly
The queen butterfly (''Danaus gilippus'') is a North and South American butterfly in the family Nymphalidae with a wingspan of . It is orange or brown with black wing borders and small white forewing spots on its dorsal wing surface, and reddish ventral wing surface fairly similar to the dorsal surface. The ventral hindwings have black veins and small white spots in a black border. The male has a black androconial scent patch on its dorsal hindwings. It can be found in meadows, fields, marshes, deserts, and at the edges of forests. This species is possibly a close relative to the similarly colored soldier butterfly (or tropical queen, '' D. eresimus''), in any case, it is not close to the plain tiger ('' D. chrysippus'', African queen) as was long believed. There are seven subspecies. Females lay one egg at a time on larval host plants. Larvae use these plants as a food source, whereas adult butterflies feed mainly on nectar from flowers. Unpalatability to avian predators is a f ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mouse Moth
The mouse moth (''Amphipyra tragopoginis'') is a moth of the family Noctuidae. It is a widespread species with a Holarctic distribution. Distribution Europe (except the extreme north, and not occurring in the south of Spain, Sicily, or the Balkans); also in Armenia, Asia Minor, Syria, Iran, Western Siberia, Kashmir (extending thence into Punjab). Recently introduced in Canada and North America. This is a rather drab but distinctive species. The forewings are uniform dark brown with three blackish spots arranged in a triangle. The hindwings are buffish, darker towards the margins. The wingspan is 32–40 mm. The common name derives from the species' habit of scuttling away on foot when disturbed rather than flying. Despite this, it can fly strongly and is attracted to light, sugar and nectar-rich flowers. In the British Isles, the adult is active from July to September.
