Boloria eunomia, the bog fritillary or ocellate bog fritillary is a butterfly of the family Nymphalidae.
The length of the forewings is 20–24 mm. The wings are orange brown with dark markings. The color of the hindwings are orangish brown with a tan postmedian band followed by a row of round silver spots. Seitz- A. aphirape Hbn. (= eunomia Esp., tomyris Hbst.) (67f). Above pale reddish yellow, with a narrow black margin and small black submarginal lunules; the basal area separated from the central area by a black dentate line and bearing heavy markings. The median area with but one very regular row of dots in the middle, at the proximal side of which there are often feeble shadows in the female. Hindwing proximally dull ochreous, with yellowish macular bands near the base and in the middle. The distal area of the hindwing beneath light yellow, with a row of small white-centred ocelli and thin hastate markings before the margin. [2]
The butterfly may be threatened by bog hydrology. [3] The males search for females in wet areas. [4] The butterfly has the subspecies triclaris (from Newfoundland to Alberta), nichollae (Alberta), and denali (Alaska and northern Yukon). The butterfly flies close to the ground. [5] The species is listed as vulnerable. [6] They eat nectar from flowers including Labrador tea and goldenrod. [4] The species flies from the end of May till the beginning of August. [6] The butterfly can be distinguished from similar species by looking on the hindwing underside; this species is the only one with a row of silvery submarginal spots. [7]
It is found throughout the north-temperate region of the Northern Hemisphere [7] including the Balkan Mountains of Bulgaria and one isolated population in Serbia. [8] The species is not mentioned in the Red Data Book of Serbian butterflies because it was not known to be in the country at the time of it being published. [8] The species is commonly found in open acid bogs in areas that are moist. [3] It can also be found in moist tundra and willow seeps. [4]
The eggs are laid in groups of 2 to 4 under the host plant leaves. [4] The eggs hatch in 7 to 8 days and after hatching, they feed on the underside of the leaves on the host plant. Caterpillars in Colorado and Wyoming are reddish brown with red spines, with third or fourth instars hibernating. The caterpillars feed on Viola species and willows. [7] The caterpillars can be found from April to June. [9] The caterpillars are silver gray with white dots. [5]
Proclossiana eunomia exhibits a polygynous mating system which is quite common in butterflies with short breeding periods. [10] With breeding periods of 5 and 7 days, respectively for males and females, there is little time to maximize matings. The butterfly Proclossiana eunomia wants to pass on as many genes as it can in its short lifespan and thus males do not discriminate, trying to court all females they encounter. On the other hand, females are a bit more selective and have been observed to refuse incoming males either by displaying a mate-refusal posture or by simply fleeing away. [10]
This pattern of mating affects the migratory behavior of Proclossiana eunomia . This physical moving of individual of a species is dependent on the density of the population. At high male densities females are harassed by willing males, resulting in female-biased emigration where females leave the imminent area. At low male densities, females are not bothered and are safe to stay in their local environment. In addition, at low female densities males might begin to emigrate out of the area in search for new unmated females whereas at high female density males already enjoy a wide selection of females without a need to migrate. The polygynous mating system of the bog fritillary whereby males freely pursue females induces a change in migratory behavior. [10]
The silver-washed fritillary is a common and variable butterfly found over much of the Palearctic realm – Algeria, Europe and across the Palearctic to Japan.
Boloria selene, known in Europe as the small pearl-bordered fritillary and in North America as the silver-bordered fritillary, is a species of butterfly of the family Nymphalidae. It is found across Europe, Asia and North America, and feeds exclusively on violets in its larval stages. This species prefers wet grassland habitats, where its larval food source, violets, are found. It overwinters in its larval stage, and eggs hatch in the late summer to early autumn. Members of this species are prey for multiple types of birds and other insects.
The pearl-bordered fritillary is a butterfly of the family Nymphalidae found in Europe and through Russia across the Palearctic to the north of Kazakhstan.
The dark green fritillary is a species of butterfly in the family Nymphalidae. The insect has a wide range in the Palearctic realm - Europe, Morocco, Iran, Siberia, Central Asia, China, Korea, and Japan.
The Niobe fritillary is a species of butterfly in the family Nymphalidae.
The Glanville fritillary is a butterfly of the family Nymphalidae. It is named for the naturalist who discovered it and the checkerboard pattern on its wings. These butterflies live in almost all of Europe, especially Finland, and in parts of northwest Africa. They are absent from the far north of Europe and parts of the Iberian Peninsula. To the east they are found across the Palearctic.
Apatura ilia, the lesser purple emperor, is a species of butterfly native to most of Europe and east across the Palearctic. It is named for its similarity to the purple emperor butterfly.
Melitaea diamina, the false heath fritillary, is a butterfly of the family Nymphalidae.
Boloria is a brush-footed butterfly (Nymphalidae) genus. Clossiana is usually included with it nowadays, though some authors still consider it distinct and it seems to warrant recognition as a subgenus at least.
The scarce fritillary is a species of butterfly in the family Nymphalidae. It is found in Austria, Bulgaria, Czech Republic, Finland, France, Germany, Greece, Hungary, Kazakhstan, Lithuania, Luxembourg, Poland, Romania, Russia, Serbia and Montenegro, and Sweden. and East across the Palearctic to Mongolia.
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, an English insect collector who claimed to have obtained the specimen within ten miles of Birmingham around 1820. However, B. dia is very rare in England and the few specimens known from there are thought to be from possibly accidental introductions.
Boloria titania, the Titania's fritillary or purple bog fritillary, is a butterfly of the subfamily Heliconiinae of the family Nymphalidae.
Melitaea didyma, the spotted fritillary or red-band fritillary, is a Palearctic butterfly of the family Nymphalidae.
Melitaea phoebe, also known as the knapweed fritillary, is a butterfly of the family Nymphalidae. It is found in the Palearctic realm, including most of Europe and North Africa, excluding the United Kingdom and Scandinavia. Previously, it also included Melitaea telona, which was recently revalidated as a distinct cryptic species.
Boloria bellona, the meadow fritillary, is a North American butterfly in the brushfoot family, Nymphalidae. The common name, meadow fritillary, is also used for a European butterfly species, Melitaea parthenoides.
Boloria frigga, the Frigga fritillary, is a butterfly of the family Nymphalidae with a circumboreal distribution. It occurs in bogs and tundra in Northern Europe to the north of 60° N, very locally in more southern locations, as well as in the Urals, Siberia, Northern Mongolia, the Russian Far East, western parts of the United States and Canada.
Boloria freija, the Freija fritillary, is a butterfly of the family Nymphalidae with a circumboreal distribution. It occurs in bogs and tundra. Its range includes Northern Europe to the north of 60° N, occasionally more southern locations, the Urals, Siberia, the Russian Far East, mountains of northern Mongolia and Hokkaido, as well as North America, extending in the Rocky Mountains to 35° N.
Euptoieta claudia, the variegated fritillary, is a North and South American butterfly in the family Nymphalidae. Even though the variegated fritillary has some very different characteristics from the Speyeria fritillaries, it is still closely related to them. Some of the differences are: variegated fritillaries have two or three broods per year vs. one per year in Speyeria; they are nomadic vs. sedentary; and they use a wide range of host plants vs. just violets. And because of their use of passionflowers as a host plant, variegated fritillaries also have taxonomic links to the heliconians. Their flight is low and swift, but even when resting or nectaring, this species is extremely difficult to approach, and, because of this, its genus name was taken from the Greek word euptoietos meaning "easily scared".
Boloria polaris, the Polaris fritillary, is a butterfly of the family Nymphalidae. It is found in northernmost Scandinavia, North America and in Greenland. It is also found in northeastern Russia and across the Palearctic to Chukotka. It is one of only six butterfly species found on Canada's Ellesmere Island.
Boloria pales, the shepherd's fritillary, is a butterfly of the family Nymphalidae. It is found from the Cantabrian Mountains and the Pyrenees through the Alps and Apennine Mountains east to the Balkan, Carpathian Mountains, the Caucasus and central Asia up to western China.
