Hamadryas feronia, the blue cracker or variable cracker, is a species of cracker butterfly in the family Nymphalidae. It is found in the southern parts of North America and South America and southwards Brazil.
Hamadryas feronia is similar in appearance to Hamadryas guatemalena and Hamadryas iphthime . The upperside of the fore wing is a mosaic pattern of white, brown and bluish-grey, with a row of small eyespots parallel with the outer margin; a small red bar occupies the discal cell. The upperside of the hind wing is similar but has few white patches and larger more distinct eyespots. The underside of the fore wing is white or whitish-tan with dark markings, a small red bar and a black submarginal eyespot, and the under hind wing is white or whitish-tan, with dark markings and blue rings containing larger eyespots near the rear margin. [1]
The larva has two colour morphs; it is either bluish-black above with brownish-white speckles and reddish spots on the side, or it is greyish-green with a pale-coloured longitudinal line on the side. It has dorsal spines on the second and third thoracic segments and on the seventh and eighth abdominal segments. The pupa has two long processes on its anterior end. [1]
Two subspecies are recognised; H. feronia feronia occurs in Brazil, Paraguay and Peru, and H. feronia farinulenta occurs in Mexico, Honduras, Venezuela, Colombia and Trinidad. This butterfly is found in open areas with trees. [1]
In Mexico, the adults are on the wing all year, but are most common between June and September. [1] The larvae feed on vines in the family Euphorbiaceae; in South America, Dalechampia triphylla is often the host plant. The adult butterflies feed on rotting fruit. They often perch head-down, flattened against the surface of tree trunks; their colouring makes them well-camouflaged against the bark. When a butterfly approaches, a male will fly out, making a characteristic cracking sound, probably by means of a pair of rods on the abdomen. If the new arrival is a male it will click in response, while if a female, it will remain silent. [1] Females also perch on tree trunks, but in an experiment it was found that when offered perching places that were black, grey or white, males showed a preference for white while females preferred grey. [2]
The meadow brown is a butterfly found in the Palearctic realm. Its range includes Europe south of 62°N, Russia eastwards to the Urals, Asia Minor, Iraq, Iran, North Africa and the Canary Islands. The larvae feed on grasses.
Pareronia valeria, the common wanderer or Malayan wanderer, is a medium-sized butterfly of the family Pieridae, that is, the yellows and whites, and is found in India and Southeast Asia. The butterfly found in India is sometimes considered as a separate species, Pareronia hippia.

Dodona ouida, the mixed Punch, is a small but striking butterfly found in the Indomalayan realm in West China, Himalayas, Northeast India (hills) and Burma that belongs to the Punches and Judies, that is, the family Riodinidae.
Cepora nadina, the lesser gull, is a small to medium-sized butterfly of the family Pieridae, that is, the yellows and whites. The species was first described by Hippolyte Lucas in 1852. It is native to Sri Lanka, India, Myanmar, Hainan, and southeast Asia.

Cracker butterflies are a Neotropical group of medium-sized brush-footed butterfly species of the genus Hamadryas. They acquired their common name due to the unusual way that males produce a "cracking" sound as part of their territorial displays. The most comprehensive work about their ecology and behavior is that of Julian Monge Najera et al. (1998). The genus was erected by Jacob Hübner in 1806.
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.
Celastrina iynteana, the Jyntea hedge blue, is a small butterfly found in India that belongs to the lycaenids or blues family.
Kaniska canace, the blue admiral, is a nymphalid butterfly, the only species of the genus Kaniska. It is found in south and southeast Asia.
Junonia almana, the peacock pansy, is a species of nymphalid butterfly found in Cambodia and South Asia. It exists in two distinct adult forms, which differ chiefly in the patterns on the underside of the wings; the dry-season form has few markings, while the wet-season form has additional eyespots and lines. It is listed as Least Concern in the IUCN Red List.
Prepona is a genus of Neotropical charaxine butterflies in the family Nymphalidae. They are strong fliers in tropical forests where they feed on fermenting fruits and animal dung. The underside of the wings is pale greyish or brownish, while the upperside is dark with distinct iridescent blue markings. A few species also have orange markings on the upperside of the wings. They are popular among butterfly collectors.
Arhopala amantes, the large oakblue, is a species of lycaenid or blue butterfly found in Asia.
Lycaena epixanthe, also known as the bog copper or cranberry-bog copper, is a North American species of butterfly in the family Lycaenidae. Adults like to sip drops of dew clinging to leaves and almost exclusively nectar on their host plant, cranberries. Because of this, bog coppers will spend their entire lives within the area of a single acid bog. Even though their flight is weak and close to the ground, bog coppers are hard to catch because of the habitat in which they live. Also, 85% of the bog coppers life span is spent in the egg. It is listed as a species of special concern in the US state of Connecticut.
Erebia pandrose, the dewy ringlet, is a member of the subfamily Satyrinae of the family Nymphalidae. It is found from the Arctic areas of northern Europe, the Pyrenees, Alps, the Apennine Mountains, the Carpathian Mountains, Kola Peninsula and Kanin Peninsula, part of the Ural and the Altai and Sayan Mountains up to Mongolia.
Acraea encedon, the common acraea, white-barred acraea or encedon acraea, is a butterfly of the family Nymphalidae. It is found in sub-Saharan Africa and south-western Arabia. It is one of the species of Acraea sometimes separated in Telchinia.
Hamadryas iphthime, the ringless blue cracker or brownish cracker, is a species of cracker butterfly in the family Nymphalidae. It was first described by Henry Walter Bates in 1864. It is found in Mexico, Central America and parts of northern South America.
Hamadryas glauconome, the pale cracker or glaucous cracker, is a species of cracker butterfly in the family Nymphalidae. It was described by Henry Walter Bates in 1864 and is found in Mexico, Central America and south to Peru. It has been recorded as an unexpected vagrant in the United States in southern Florida, Arizona and Texas.
