Pyrgus Centaureae
The northern grizzled skipper (''Pyrgus centaureae'') is a species of skipper butterfly (family Hesperiidae) with a range in North America from the subarctic to the north, New Mexico to the south, and the Appalachian Mountains to the east. While generally similar to most other ''Pyrgus'' species, this species has a greyer brown background colour with bold white spots on both the forewing and hindwing. Unlike most other ''Pyrgus'' species, the veins on the underside are obviously lined white. Wingspan is 25 to 33 mm. One generation is produced per year in its southern range from March to May. Two years are required for each brood in the subarctic. Larval food plants include cloudberry ''Rubus chamaemorus'' is a species of flowering plant in the rose family Rosaceae, native to cool temperate regions, alpine and arctic tundra and boreal forest. This herbaceous perennial produces amber-colored edible fruit similar to the blackbe ... (''Rubus chamaemorus''), wild strawberry ...

Insect Wing
Insect wings are adult outgrowths of the insect exoskeleton that enable insects to fly. They are found on the second and third thoracic segments (the mesothorax and metathorax), and the two pairs are often referred to as the forewings and hindwings, respectively, though a few insects lack hindwings, even rudiments. The wings are strengthened by a number of longitudinal veins, which often have cross-connections that form closed "cells" in the membrane (extreme examples include the dragonflies and lacewings). The patterns resulting from the fusion and cross-connection of the wing veins are often diagnostic for different evolutionary lineages and can be used for identification to the family or even genus level in many orders of insects. Physically, some insects move their flight muscles directly, others indirectly. In insects with direct flight, the wing muscles directly attach to the wing base, so that a small downward movement of the wing base lifts the wing itself upward. Those i ...

Pyrgus Centaureae Wyandot
''Pyrgus centaureae wyandot'', the Appalachian grizzled skipper, is a small, brown, gray and white butterfly known to inhabit parts of the Appalachian highlands and Northern Michigan. It can be identified by its characteristic checkered wing pattern formed by the scales on the fore- and hindwings. The butterflies are known to prefer sites with minimal vegetation, such as open areas in hardwood forests, as well as sites of recent disturbance. The skipper's main larval food plants include Canada cinquefoil (''Potentilla canadensis'') and wild strawberry (''Fragaria virginiana'') depending on the specific population's range. The butterfly is listed as a federal species of concern and holds a stated-endangered title in Ohio and New Jersey. Description The Appalachian grizzled skipper butterfly is a subspecies of the butterfly ''Pyrgus centaureae'' or northern grizzled skipper. The Appalachian skipper is characterized by its gray and brown top color, distinctive white checkered mar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varileaf Cinquefoil
''Potentilla diversifolia'' or ''Potentilla × diversifolia'' is a species of flowering plant in the Rose Family (Rosaceae) known by the common names varileaf cinquefoil, different-leaved cinquefoil, and mountain meadow cinquefoil.Great Basin Wildflowers, Laird R. Blackwell, 2006, p. 167 Distribution and habitat It is native to North America, where it grows in moist habitat in many regions, in Alaska to Greenland, the Pacific Northwest and the Rocky Mountains, and from California to New Mexico. Festuca association This cinquefoil is a dominant plant in association with the grass ''Festuca idahoensis'' on the alpine slopes of mountainous western Montana and central Idaho. Description ''Potentilla diversifolia'' has gray-green leaves divided into usually five leaflets, which are mostly hairless and are deeply lobed or have teeth along their distal margins. Most of the leaves are low on the stem, with smaller ones occurring above. The inflorescence is a cyme of several flowers. E ...

Potentilla Canadensis
Potentilla canadensis, the dwarf cinquefoil, is a species of cinquefoil (genus ''Potentilla'') native to North America. The Iroquois take a pounded infusion of the roots as an antidiarrheal. The Natchez give the plant as a drug for those believed to be bewitched. Along with ''Potentilla simplex'', the plant is an indicator of impoverished soil as well as the host species for the cinquefoil bud gall wasp ''Diastrophus potentillae ''Diastrophus potentillae'', also known as the cinquefoil bud gall wasp, is a species of gall wasp in the family Cynipidae.

Fragaria Virginiana
''Fragaria virginiana'', known as Virginia strawberry, wild strawberry, common strawberry, or mountain strawberry, is a North American strawberry that grows across much of the United States and southern Canada. It is one of the two species of wild strawberry that were hybridized to create the modern domesticated garden strawberry (''Fragaria'' × ''ananassa''). Subspecies There are four recognized subspecies: :*''Fragaria virginiana'' subsp. ' (formerly known as ''F. ovalis'') :*''Fragaria virginiana'' subsp. ''grayana'' :*''Fragaria virginiana'' subsp. ''platypetala'' :*''Fragaria virginiana'' subsp. ''virginiana'' Cytology All strawberries have a base haploid count of 7 chromosomes. ''Fragaria virginiana'' is octoploid, having eight sets of these chromosomes for a total of 56. These eight genomes pair as four distinct sets, of two different types, with little or no pairing between sets. The genome composition of the octoploid strawberry species has generally been indicated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cloudberry
''Rubus chamaemorus'' is a species of flowering plant in the rose family Rosaceae, native to cool temperate regions, alpine and arctic tundra and boreal forest. This herbaceous perennial produces amber-colored edible fruit similar to the blackberry. English common names include cloudberry, nordic berry, bakeapple (in Newfoundland and Labrador), knotberry and knoutberry (in England), aqpik or low-bush salmonberry (in Alaska – not to be confused with salmonberry, ''Rubus spectabilis''), and averin or evron (in Scotland). Description Unlike most ''Rubus'' species, the cloudberry is dioecious, and fruit production by a female plant requires pollination from a male plant. The cloudberry grows to high. The leaves alternate between having 5 and 7 soft, handlike lobes on straight, branchless stalks. After pollination, the white (sometimes reddish-tipped) flowers form raspberry-sized aggregate fruits which are more plentiful in wooded rather than sun-exposed habitats. Consisting of ...

Larva
A larva (; plural larvae ) is a distinct juvenile form many animals undergo before metamorphosis into adults. Animals with indirect development such as insects, amphibians, or cnidarians typically have a larval phase of their life cycle. The larva's appearance is generally very different from the adult form (''e.g.'' caterpillars and butterflies) including different unique structures and organs that do not occur in the adult form. Their diet may also be considerably different. Larvae are frequently adapted to different environments than adults. For example, some larvae such as tadpoles live almost exclusively in aquatic environments, but can live outside water as adult frogs. By living in a distinct environment, larvae may be given shelter from predators and reduce competition for resources with the adult population. Animals in the larval stage will consume food to fuel their transition into the adult form. In some organisms like polychaetes and barnacles, adults are immobil ...

Skipper (butterfly)
Skippers are a family of the Lepidoptera (moths and butterflies) named the Hesperiidae. Being diurnal, they are generally called butterflies. They were previously placed in a separate superfamily, Hesperioidea; however, the most recent taxonomy places the family in the superfamily Papilionoidea, the butterflies. They are named for their quick, darting flight habits. Most have their antenna tips modified into narrow, hook-like projections. Moreover, skippers mostly have an absence of wing-coupling structure available in most moths. More than 3500 species of skippers are recognized, and they occur worldwide, but with the greatest diversity in the Neotropical regions of Central and South America.Ackery et al. (1999) Description and systematics Traditionally, the Hesperiidae were placed in a monotypic superfamily Hesperioidea, because they are morphologically distinct from other Rhopalocera (butterflies), which mostly belong to the typical butterfly superfamily Papilionoidea.

Pyrgus
''Pyrgus'' is a genus in the skippers butterfly family, Hesperiidae, known as the grizzled skippers. The name "checkered" or "chequered skipper" may also be applied to some species, but also refers to species in the genera '' Burnsius'' and '' Carterocephalus''. They occur in the Holarctic with an additional group of species extending to the Neotropic. In 2019, most of the species of ''Pyrgus'' found in the North, Central, or South America were moved to the genera '' Burnsius'', ''Chirgus'', and '' Heliopetes''. The remaining ''Pyrgus'' species found in the New World are ''Pyrgus centaureae'', ''ruralis'', ''scriptura'', and ''xanthus''. Species These species belong to the genus ''Pyrgus'': * '' Pyrgus accretus'' (Verity, 1925) * '' Pyrgus alpinus'' Erschoff, 1874 * '' Pyrgus alveus'' (Hübner, 1803) (large grizzled skipper) * '' Pyrgus andromedae'' (Wallengren, 1853) (Alpine grizzled skipper) * '' Pyrgus armoricanus'' (Oberthur, 1910) (oberthür's grizzled skipper) * ''Pyrgu ...
