Shannon-Wiener Index of Biodiversity:1.46

Distinguishing morphological features of Order: Adults have four membranous wings (rarely wingless); hindwings are usually smaller than forewings, both largely or entirely covered with scales.Wing scales often produce distinctive color patterns that play an important role in courtship and intraspecific recognition Adult mouthparts adapted for sucking, the proboscis is usually in the form of a coiled tube (adults of some species lack mouthparts and do not feed as adults)

Sub-order: Glossata

Order: Lepidoptera

genus and species ?

Geographical Distribution: They are Common worldwide, except Antarctica

Life cycle:Holometabola;These insects undergo complete metamorphosis; egg, larva (the caterpillar), pupa (chrysalis or cocoon), and adult.The larval stage does most of the eating and growing, with the adults often staying alive just long enough to mate and lay eggs.

Sexual dimorphism: is widespread and almost completely determined by genetic determination. Apart from color variation, which may differ from slight to completely different color-pattern combinations, secondary sexual characteristics may also be present.Polymorphic and/or mimetic females occur in the case of some taxa to obtain a level of protection not available to the male of their species. The most distinct case of sexual dimorphism is that of adult females species who have only vestigial wings, legs, and mouthparts as compared to the adult males who are strong fliers with well-developed wings and feathery antennae.

What it eats:Most lepidopteran larvae are herbivores; some species eat foliage, some burrow into stems or roots, and some are leaf-miners.Most adult moths and butterflies use their coiled mouthparts to suck nectar from flowers.

Habitat: They inhabit all terrestrial habitats ranging from desert to rainforest, from lowland grasslands to montane plateaus but almost always associated with higher plants, especially angiosperms (flowering plants)

Ecological importance: Butterflies and moths play an important role in the natural ecosystem as pollinators and as food in the food chain; conversely, their larva are considered very problematic to vegetation in agriculture, as their main source of food is often live plant matter

Economic/agricultural/human importance: larvae of the lepidoptera are probably more destructive to agricultural crops and forest trees than any other group of insects. Many moth and butterfly species are of economic interest by virtue of their role as the silk they produce or as pest species.
