Boloria Dia
''Boloria dia'', the Weaver's fritillary or violet fritillary, is a butterfly in the family Nymphalidae. The name Weaver's fritillary is in honor of Richard Weaver (entomologist), Richard Weaver, an English insect collector who claimed to have obtained the specimen within ten miles of Birmingham around 1820. However, ''B. dia'' is uncommon in England and the few specimens known from there are thought to be from possibly accidental introductions. Description The adult is a small fritillary with typically chequered orange-brown upperside and a submarginal row of triangles and dots. The forewing is 16–17 mm long. The underside of the hindwing has a distinctive purplish band. ''B. dia'' differs from the pearl-bordered fritillary in having a sharp angle to its hindwing (readily seen from underside when perched with wings closed). The similar Titania's fritillary has a less sharply-angled hindwing and only occurs at high altitude. In Europe the larvae feed on ''Viola (plant), ...

Butterflies Of Asia
Butterflies are insects in the macrolepidopteran clade Rhopalocera from the order Lepidoptera, which also includes moths. Adult butterflies have large, often brightly coloured wings, and conspicuous, fluttering flight. The group comprises the large superfamily Papilionoidea, which contains at least one former group, the skippers (formerly the superfamily "Hesperioidea"), and the most recent analyses suggest it also contains the moth-butterflies (formerly the superfamily "Hedyloidea"). Butterfly fossils date to the Paleocene, about 56 million years ago. Butterflies have a four-stage life cycle, as like most insects they undergo complete metamorphosis. Winged adults lay eggs on the food plant on which their larvae, known as caterpillars, will feed. The caterpillars grow, sometimes very rapidly, and when fully developed, pupate in a chrysalis. When metamorphosis is complete, the pupal skin splits, the adult insect climbs out, and after its wings have expanded and dried, it fli ...

Rhododendron Lapponicum
''Rhododendron lapponicum'' (高山杜鹃), the Lapland rosebay, is a dwarf rhododendron species found in subarctic regions of North America, Europe and Asia, where it grows at altitudes ranging from sea level to . It is an evergreen prostrate shrub growing to in height, with leaves that are oblong-elliptic or ovate-elliptic to oblong-obovate The following is a list of terms which are used to describe leaf morphology in the description and taxonomy of plants. Leaves may be simple (a single leaf blade or lamina) or compound (with several leaflets). The edge of the leaf may be regular ..., 0.4–1.5 by 0.2–0.5 cm in size. The flowers are reddish or purple. Despite numerous attempts, this dwarf species has proved difficult to cultivate, possibly because it requires very cool, moist conditions and snow cover for part of the year.

Empetrum Nigrum
''Empetrum nigrum'', crowberry, black crowberry, or, in western Alaska, blackberry, is a flowering plant species in the heather family Ericaceae with a near circumboreal distribution in the Northern Hemisphere. It is usually dioecious, but there is a bisexual tetraploid subspecies, ''Empetrum nigrum'' subsp. ''hermaphroditum'', which occurs in more northerly locations and at higher altitude.

Dryas (plant)
''Dryas'' is a genus of perennial cushion-forming evergreen dwarf shrubs in the family Rosaceae, native to the arctic and alpine regions of Europe, Asia and North America. The genus is named after the dryads, the tree nymphs of ancient Greek mythology. The classification of ''Dryas'' within the Rosaceae has been unclear. The genus was formerly placed in the subfamily Rosoideae, but is now placed in subfamily Dryadoideae. The species are superficially similar to ''Geum'' (with which they share the common name avens), ''Potentilla'', and ''Fragaria'' (strawberry). However, ''Dryas'' are distinct in having flowers with ''eight'' petals (rarely seven or up to ten), instead of the five petals found in most other genera in the Rosaceae. The flowers are erect and white with a yellow centre (''Dryas integrifolia'', ''Dryas octopetala'') or pendulous and all-yellow ('' Dryas drummondii''), and held conspicuously above the small plants. This makes them very popular in rockeries and alpine ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
