Butterfly: It’s an insect of the Order Lepidoptera, and belongs to one of the superfamilies Hesperioidea (the skippers) or Papilionoidea (all other butterflies). Some authors would include also members of the superfamily Hedyloidea, the American butterfly moths. They are notable for their usual life cycle—proceeding from the larval stage as caterpillars through a pupic metamorphisis into their winged adult form. The patterns formed by their brightly coloured wings and their erratic-yet-graceful flight has made
butterfly watching a popular hobby.

Insect: It’s an invertebrate that is taxonomically referred to as the class Insecta. They are the most numerous and most widespread terrestrial taxon within the phylum Arthropoda, and indeed the most diverse group of animals on the earth, with around 925,000 species described—more than all other animal groups combined. Insects may be found in nearly all environments on the planet, although only a small number of species have adapted to life in
the oceans where crustaceans tend to predominate.

Lepidoptera: It’s the second largest order in the class insecta and includes the butterflies, skippers, and moths. Members of the order are referred to as lepidopterans. A person who collects or studies this order is referred to as a Lepidopterist. This order has more than 180,000 species in 127 families and 46 superfamilies. It is second only to the Coleoptera (the beetles) in number of described species. The name is derived from Greek "scaly-wing"
(lepido-pteron).

Morpho: They are neotropical butterflies found mostly in South America. Morphos range in wingspan from the 7.5 cm (3 inch). The name Morpho
derives from its use as an epithet of Venus.
Many Morpho butterflies are coloured in metallic, shimmering shades of blue and green. These colours are not a result of pigmentation but rather are an example of iridescence: the extremely fine lamellated 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 colours 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 called a photonic crystal. The iridescent lamellae are present on the dorsal side of their wings only, leaving the ventral side a drab brown. The ventral side is decorated with ocelli or eyespots. While not all Morphos have iridescent coloration, they all have ocelli. In most species only the males are colourful, a fact 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 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 Peruvian species are reportedly visible by the human eye
up to one kilometre away.

Moth: It’s an insect closely related to the butterfly. Both are of the order Lepidoptera. Most species of moth are nocturnal, but there are crepuscular and diurnal species. They can be distinguished from butterflies in several ways. Moths, and more particularly their caterpillars, are a major agricultural pest in many parts of the world. In temperate climates, the codling moth
causes extensive damage, especially to fruit farms.

Nymphalidae: It’s a family of about 5,000 species of butterflies. These are typically fairly large butterflies, such as the emperor, admirals, tortoiseshells and fritillaries, which have very colourful wings. However, the underwings are dull and often look like dead leaves, which produces a cryptic effect that helps the butterfly disappear in its surroundings. The front two legs are small, so these butterflies are effectively four-legged. The caterpillars are hairy or
spiky, and the chrysalids have shiny spots.
The current classification of Nymphalidae includes the following subfamilies:
• Apaturinae
• Biblidinae
• Calinaginae
• Charaxinae
• Cyrestinae
• Danainae
• Heliconiinae
• Libytheinae
• Limenitidinae
• Morphinae
• Nymphalinae
• Satyrinae

Papilionoidea: The superfamily Papilionoidea contains all the butterflies except for the skippers. The members of the Papilionoidea may be
distinguished by the following combination of characters :

• the body is smaller and less moth-like.
• the wings are larger.
• the antennae are straight and clubbed (rather than hooked as in the skippers).
• the caterpillars do not spin cocoons to pupate in.
• the pupae are angular rather than rounded.

Skipper: A group of insects in the order Lepidoptera. The skippers are usually counted as butterflies, but they are somewhat intermediate between the rest of the butterflies and the remaining Lepidoptera, the moths.
Skippers are classified in the superfamily Hesperioidea, which includes only one family, the Hesperiidae. They differ in several important ways from the remaining butterflies, which are classified in superfamily Papilionoidea. Skippers have the antennae clubs hooked backward, have stocky bodies, and possess stronger wing muscles and better eyes. Nonetheless, the two superfamilies are regarded as sister taxa, so the butterflies collectively form a true clade. In fact, some taxonomists place the family Hesperiidae within
the superfamily Papilionoidea.

Tarantula: True tarantulas are spiders belonging to the family Theraphosidae (Greek for thera "wild animal, beast" + phos "light"). They are characterized by having tarsi (feet) with two claws and claw tufts, called scopulae. Related families include the funnel-web spiders and the trap door spiders, which sometimes are also called tarantulas. The family Theraphosidae includes over 800 different species of tarantulas, divided over 12 subfamilies (formerly 13) and 113 genera.
Tarantulas are long-legged, long-living spiders, whose entire body is covered with short glittery hairs called setae. Tarantulas inhabit tropical to temperate regions in South America and Central America, Asia, Southern Europe, Africa and Australia.
