Gatekeeper Butterfly

Gatekeeper Butterfly
Gatekeeper Butterfly by billnbenj

The Gatekeeper (Pyronia tithonus) sometimes called the Hedge Brown is a common butterfly in the United Kingdom. It is a member of the subfamily Satyrinae in the family Nymphalidae. A similar species is the Meadow Brown, especially in the female sex, which likes to rest with closed wings however, especially the far less active females.

The name "Gatekeeper" may refer to its frequent occurrence near field gates and to the man who was responsible for the toll gates in the eighteenth and nineteenth centuries when butterflies were more numerous than they are today. As indicated by its alternate name, the gatekeeper butterfly prefers the habitat of meadow margins and hedges; field gates are often in such locations, and thus the Gatekeeper can be found much more frequently in such locations than the Meadow Brown for example.

Regal Fritillary

Regal fritillary (Speyeria idalia)
Regal Fritillary by Matthew Ignoffo

Speyeria idalia, commonly known as the Regal Fritillary, is a striking nymphalid butterfly found among some of the remaining tallgrass and mixed-grass prairies in the east-central United States. This prairie-specialist butterfly has a characteristic deep orange color and unmistakable dark hindwings with two bands of spots (Brock 2003). On the female, both bands of spots are white. However, on the male, the outer band of spots is orange in color.

Females also tend to be slightly larger than males. The ventral surface of the hindwings is olive brown to black in color with bold silvery white spots (Selby 2007). The wingspan of S. idalia usually measures somewhere between 2.69 and 4.13 inches (Selby 2007). Flight is in the summertime from approximately June to September and adults tend to be swift in flight, coasting close to the ground (Brock 2003).

Regal fritillary larvae are approximately 0.08 inches long after they hatch and reach a length of approximately 1.75 inches when fully developed (Edwards 1879). The mature larvae have a black body with yellowish-orange bands and stripes. There are yellowish middorsal and lateral stripes and a number of dorsal, subdorsal, and lateral fleshy spines extending from the body. The head of the mature larvae is rounded and small, orangish-red on top and black underneath (Edwards 1879).

The larval food source for the regal fritillary and all members of the genus Speyeria are violets (Viola spp.) (Selby 2007). The violets are an extremely important component of habitat sustainability for the regal fritillary and there is a correlation between the number of violets present and the number of butterflies found in a given area (Kelly and Debinski 1998). Violet species that the larvae feed on include, Viola pedata (bird’s-foot violet), V. pedatifida (blue prairie violet), V. papilionacea (common blue violet), V. lanceolata (lance-leafed violet), V. nuttallii (Nuttall’s Violet) (Kelly and Debinski 1998), V. sagittata (arrowleaf violet), and V. tricolor (Johnny Jumpup) (Selby 2007). These various violet species are associated with the different areas of the regal fritillary’s range. For example, the bird’s-foot violet and the prairie violet tend to be the preferred larval food source for the regal in the Midwest and Great Plains regions (Selby 2007).

The adult butterflies may feed on a variety of nectar plants and their availability throughout the summer flight time can be as important as the presence of larval food plants in determining whether an area can support populations of butterfly species (Selby 2007). Milkweeds, thistles, coneflowers, blazing-stars, bergamots, clovers, goldenrods, and ironweeds are some of the most important nectar sources for adult regal fritillaries.

Milkweeds and thistles have been observed to be the preferred nectar source throughout the regal fritillary’s range (Selby 2007). These two types of plants provide a constant supply of nectar due to their staggered growth times. Common milkweed starts blooming when male regal fritillaries begin to emerge early in the summer and thistles tend to bloom later in the season which is crucial to females approaching oviposition (Selby 2007).

Small Heath

Small Heath butterfly
Small Heath by Ian-S

The Small Heath Coenonympha pamphilus is a butterfly species belonging to the family Nymphalidae, (subfamily Satyrinae, commonly known as "the Browns"). It is widespread in Eurasia and northwestern Africa, preferring drier habitats than other Coenonymphae. The larval host plants are grasses, notably Sheep's Fescue.

Small Heath Butterfly - (Coenonympha pamphilus)
Small Heath by benwmbc

The butterfly loosely resembles a small Meadow Brown, but the brown colour of the wings appears noticeably paler in flight. Unlike the Meadow Brown and other common members of Satyrinae, the Small Heath is a lateral basker, only ever resting with its wings closed and angled at 90° to the sun.

Small Heath Butterfly

The larvae have lifespans of varying length, even within the same climate, thus the imagines of one generation may be seen over a long period. The butterfly usually has two, occasionally three, broods and is on the wing from mid May until early October (late June to mid August in colder climates). The insect overwinters in its larval stage.

The Small Heath, like its cousin the Wall Brown, has been in serious decline across much of southern England for reasons unclear, and was accordingly designated as a UK BAP Priority Species (research only) by DEFRA in 2007.

Peacock Butterfly by Glockenblume

The European Peacock butterfly (Inachis io), more commonly known simply as the Peacock butterfly, is a well-known colourful butterfly, found in temperate Europe and Asia. It is the only member of the genus Inachis which is sometimes included in Nymphalis. It should not be confused or classified with the "American peacocks" in the genus Anartia; these are not close relatives of the present species. The peacock butterfly is resident in much of its range, often wintering in buildings or trees. It therefore often appears quite early in spring.

Peacock Butterfly

The butterfly hibernates over winter before laying its eggs in early spring, in batches of up to 500 at a time. The caterpillars, which are shiny black with six rows of barbed spikes and a series of white dots on each segment, hatch after about a week and feed on nettles and hops.

The adult butterflies drink nectar from a wide variety of flowering plants, including buddleia, willows, dandelions, wild marjoram, danewort, hemp agrimony, and clover; they also utilize tree sap and rotten fruit.

Common Snout Butterfly by jim_mcculloch

Libytheana carinenta, the American or Common Snout Butterfly, is a member of the Libytheinae subfamily, in the brush-footed butterfly family Nymphalidae. This species is found in both North and South America. The larval host plants are Celtis spp. on which the eggs are laid singly. Massive migrations of this species often attract attention in the Texas and Mexican newspapers.

Common Snout Butterfly
Common Snout Butterfly by Juggler Jim

Snout butterflies have prominent elongated mouthparts (labial palpi) which, in concert with the antennae, give the appearance of the petiole (stem) of a dead leaf. Snouts often take advantage of their brilliant camouflage by hanging upsidedown under a twig, making them nearly invisible. Wings are patterned black-brown with white and orange markings.

The fore wings have a distinctive squared off, hook-like (falcate) tip. Caterpillars appear humpbacked, having a small head, swollen first and second abdominal segments, and a last abdominal segment that is tapered and rounded. They are dark green with yellow stripes along the top and sides of the body, and have two black tubercles on the top of the thorax.

Marsh Fritillary

Marsh Fritillary
Marsh Fritillary by mattberry

The Marsh Fritillary (Euphydryas aurinia) is a butterfly of the Nymphalidae family.

The Marsh Fritillary is in decline in Europe and one of 11 butterflies covered by the United Kingdom Biodiversity Action Plan. The UK distribution can be seen on the National Biodiversity Network.

The adult butterflies are marked in checkered marking of gold and brown with a black background. The underside of the wings is patterned with yellow orange and black without any silver coloration at all. The eggs are yellow identified by being in a large batch,and the larvae are black.

Marsh Fritillary by camerar

The Marsh Fritillary is usually to be found in damp heathy grasslands which are called Rhos Pastures from the Welsh word Rhos meaning Heath. but the species does exist in other types of habitats which are drier, like neutral grasslands or dry calcareous grasslands. Small populations may be seen where there is not a lot of the larval foodplant present. Small populations can be an important element of the ecology because they can produce lots of mobile individuals which can found other populations.

The Marsh Fritillary is protected under British Law. It is listed under Schedule 5 of the Wildlife and Countryside Act, also the EC Habitats and Species Directive (Annex II).

The butterflies fly from the April until July depending on latitude and altitude.

MOURNING CLOAK WITH FRIENDS
Mourning Cloak by TJCLARK

Nymphalis antiopa, known as the Mourning Cloak in North America and the Camberwell Beauty in the British Isles, is a large butterfly native to Eurasia and North America. The immature form of this species is sometimes known as the spiny elm caterpillar. Other older names for this species include Grand Surprise and White Petticoat. A powerful flier, this species is sometimes found in areas far from its usual range during migration. It is also the State Insect of Montana.

California Tortoiseshell

California Tortoiseshell, Nymphalis californica
California Tortoiseshell by Bill Bouton

The California Tortoiseshell (Nymphalis californica) is a butterfly of the Nymphalidae family.

The California Tortoiseshell is known for having population explosions which cause the butterflies to migrate to new areas. The cause of these seemingly random population explosions is unknown. Their larvae eat various species of Ceanothus.

It is recognized for the top of its wings being orange with big black spots (used mainly for camouflage). The underside of its wings look literally like a dead leaf, because when it has its wings up during rest it looks like a dead leaf on the ground. Its wingspan varies from 3.2–7 cm (1¼–2¾ inches).

Morpho Butterfly

Blue Morpho Butterfly
Morpho Butterfly by Sheryl Tollenaar

A Morpho butterfly may be one of over 80 species of the genus Morpho. They are Neotropical butterflies found mostly in South America as well as Mexico and Central America. Morphos range in wingspan from the 7.5 cm (3 inch) M. rhodopteron to the imposing 20 cm (8 inch) Sunset Morpho, M. hecuba. The name Morpho, meaning changed or modified, is also an epithet of Aphrodite and Venus.

Blue Morpho Butterfly
Morpho Butterfly by rich66~

Many Morpho butterflies are colored in metallic, shimmering shades of blue and green. These colors are not a result of pigmentation but are an example of iridescence: the microscopic scales covering the Morpho's wings reflect incident light repeatedly at successive layers, leading to interference effects that depend on both wavelength and angle of incidence/observance. Thus the colors produced vary with viewing angle, however they are actually surprisingly uniform, perhaps due to the tetrahedral (diamond-like) structural arrangement of the scales or diffraction from overlying cell layers. This structure may be likened to a photonic crystal. The lamellate structure of their wing scales has been studied as a model in the development of fabrics, dye-free paints, and anti-counterfeit technology used in currency.

The iridescent lamellae are only present on the dorsal side of their wings, leaving the ventral side brown.

The ventral side is decorated with ocelli or eyespots. In some species, such as M. godarti, the dorsal lamellae are so thin as to allow the ventral ocelli to peek through. While not all Morphos have iridescent coloration, they all have ocelli. In most species only the males are colorful, supporting the theory that the coloration is used for intrasexual communication between males. The lamellae reflect up to 70% of light falling on them, including any ultraviolet (UV). The eyes of Morpho butterflies are thought to be highly sensitive to UV light and therefore the males are able to see each other from great distances. Some South American species are reportedly visible by the human eye up to one kilometre away.

There also exist a number of white Morpho species, principal among these being M. catenarius and M. laertes. An unusual species that is fundamentally white in coloration, but which exhibits a stunning purple iridescence when viewed at certain angles is the rare M. sulkowskyi, while among the metallic blue Morpho species, M. rhetenor stands out as the most iridescence of all, with M. cypris a close second. Indeed, M. cypris is notable in that specimens that are mounted in entomological collections will exhibit color differences across the wings if they are not 'set' perfectly flat.

Comma Butterfly

Comma (Polygonia c-album)
Comma (Polygonia c-album) by William Richardson

The Comma (Polygonia c-album) is a species of butterfly, common in the United Kingdom and with a distribution across Europe and temperate Asia to Japan and south to Morocco. Similar species are found in the United States and Canada. It has a white marking on its underwings resembling a comma. The wings have a distinctive ragged edge, apparently a cryptic form as the butterfly resembles a fallen leaf. The caterpillars are also cryptic, resembling a bird dropping.

In the 19th century the British population of comma butterflies crashed, and by 1920 there were only two sightings. The cause for this decline is unknown, and from about 1930 the population recovered and it is now one of the more familiar butterflies in Southern England, and is now resident in Scotland and in North Wales.

Comma - Nymphalis c-album (Nymphalidae)
Comma (Polygonia c-album) by Rachael Hickling

The caterpillars will feed up on hops, and they will also eat stinging nettle, elm or currant leaves, and in other parts of its distribution (e.g. in Sweden) also sallow and birch leaves.

The species survives the winter in the adult stage, and adults are of two forms. The form that overwinters before reproducing has dark undersides of the wings, whereas the form that develops directly to sexual maturation has lighter colured wing undersides. Both forms can arise from eggs laid by the same female, depending mainly on the photoperiods experienced by the larvae, but also with an influence of host plants, temperature and sex of individuals.

White Admiral

Showoff
White Admiral by BugMan50

The (Eurasian) White Admiral (see also Limenitis arthemis), Limenitis camilla, is a butterfly of the Nymphalidae family. They are found in woodland throughout southern Britain and much of Europe and Asia, extending as far east as Japan.

Adult white admirals have black wings with white bands. The contrasting colours help to break up the outline of the wing, camouflaging it from predators. They have a wing span of approximately 60-65 mm and have a distinctive, elegant flight comprising of short periods of wing beats, followed by long glides.

White Admiral
White Admiral by BugMan50

The white admiral feeds on bramble blossom and honeydew and the female will lay its eggs singly on wisps of honeysuckle growing in dense woodland. The caterpillars are green with red-brown hairs and are camouflaged on a leaf, by a mixture of their own dropping and silk. As autumn approaches it will form a tent-like structure made of leaf tissue known as a hibernaculum which it then secures to the stem with silk before hibernating. The caterpillar will then awaken the following spring and after a brief spell of feeding will moult, revealing a spiny green skin. It will then pupate during the summer, forming a green and gold chrysalis. After approximately two weeks the adult will emerge.

Monarch Butterfly

Monarch Butterfly
Monarch Butterfly by Creativity+ Timothy K Hamilton

The Monarch (Danaus plexippus) is a milkweed butterfly (subfamily Danainae), in the family Nymphalidae. It is perhaps the best known of all North American butterflies. Since the 19th century, it is also found in New Zealand, and since 1871 in Australia, where it is called the Wanderer. In Australia it is also known as the wanderer butterfly.

In Europe it is resident in the Canary Islands the Azores and Madeira, and is found as an occasional migrant in Western Europe. Its wings feature an easily recognizable orange and black pattern, with a wingspan of 8.9–10.2 centimetres (3½–4 in). (The Viceroy butterfly has a similar size, color, and pattern, but can be distinguished by an extra black stripe across the hindwing.) Female Monarchs have darker veins on their wings, and the males have a spot in the center of each hindwing from which pheromones are released. Males are also slightly larger.

Common Buckeye

Common Buckeye Butterfly...
Common Buckeye Butterfly by pieceoflace

Junonia coenia is the Common Buckeye butterfly. It is found in all parts of the United States except the northwest, and is especially common in the South, the California coast, and throughout Central America. Its habitat is open areas with low vegetation and some bare ground. The bold pattern of eyespots and white bars on the upper wing surface is distinctive in much of its range, though compare related species in the same genus.

(These are Mangrove Buckeye, Junonia evarete and Tropical Buckeye, Junonia genoveva, formerly considered one species, the Smoky Buckeye, Junonia evarete.) The eyespots likely serve to startle or distract predators, especially young birds. The species has many flights throughout the year, with mostly northward migrations for the summer. Much of the northern United States is only colonized in the fall from southern populations. Some of the later broods move southwards in the fall. Common buckeyes exhibit seasonal polyphenism, the summer version of the butterfly has light yellowish ventral wings and is called "linea". The Fall morph has pink ventral wings, and is called the "rosa" morph.

A not so Common Buckeye...
Common Buckeye photo by pieceoflace

Adults feed on nectar and also take fluids from mud and damp sand. Males perch on bare ground or low plants, occasionally patrolling in search of females, but they are not territorial. The female lays eggs singly on buds or the upper side of leaves. The caterpillars are solitary and feed on the foliage, flowers, and fruits of the host plant.

A variety of (typically) herbaceous plants are used, including especially plants in the snapdragon family (Scrophulariaceae). These include snapdragon (Antirrhinum), toadflax (Linaria), and Gerardia. Caterpillars also feed on plants of the plantain family, such as Plantago; and the Acanthus family including ruellia (Ruellia nodiflora). Larvae feed singly. Adults and some larvae overwinter in southern areas. The pupa may not have a resting phase (diapause), as in many other butterflies.

This species and its relatives were placed formerly in the genus Precis.

The Common Buckeye was featured on the 2006 United States Postal Service 24-cent postage stamp.
