BUTTERFLYS!

  1. 1. BBUUTTTTEERRFFLLYYSS!!BY VANIA ISLAS
  2. 2. ABOUT BUTTERFLIES!! <3Butterflies are beautiful, flying insects with large scaly wings. Like all insects, theyhave six jointed legs, 3 body parts, a pair of antennae, compound eyes, and anexoskeleton. The three body parts are the head, thorax (the chest), and abdomen (thetail end).Butterflies are very good fliers. They have two pairs of large wings covered withcolorful, iridescent scales in overlapping rows. Lepidoptera (butterflies and moths) arethe only insects that have scaly wings. The wings are attached to the butterflys thorax(mid-section). Veins support the delicate wings and nourish them with blood.
  3. 3. LIFE CYCLE!LIFE CYCLE!Butterflies and moths undergo complete metamorphosis in which they go through four different life stagesEgg - A butterfly starts its life as an egg, often laid on a leafLarva - The larva (caterpillar) hatches from an egg and eats leaves or flowers almost constantly. Thecaterpillar molts (loses its old skin) many times as it grows. The caterpillar will increase up to severalthousand times in size before pupating.Pupa - It turns into a pupa (chrysalis); this is a resting stage.Adult - A beautiful, flying adult emerges. This adult will continue the cycle.

  5. 5. what they eatA caterpillar’s first meal is its owneggshell. It then spends most of its timeeating the leaves of the plant on which ithatched. An adult butterfly uncoils itslong, straw-like proboscis to sip nectarfrom flowers, juice from rotting fruitand water from puddles.
  6. 6. PopulationExact numbers are notknown since there areabout 17,500 species ofbutterflies spreadthroughout almost theentire world.
  7. 7. RANGEButterflies are foundworldwide except on thecontinent of Antarctica.Many species migrate toavoid adverse conditions.Most migrate relatively shortdistances, but monarchs andseveral other species migrate
  8. 8. SIZE: Butterflies come in a variety of sizes. Theworld’s smallest known species, the bluepygmy found in southern California, has awingspan of just over half an inch. Thelargest species, New Guinea’s QueenAlexandras birdwing, can measure up totwelve inches from wingtip to wingtip.
  9. 9. LIFE SPANThe average lifespan for an adultbutterfly is 20 to 40 days. Somespecies live no longer than threeor four days; others may live upto six months.
  10. 10. HOW THEY DEFENDTHEMSELVESMany butterflies have developed interesting ways of defending themselves frompredators. One method is disguise, or “cryptic coloration”, where the butterfly has theability to look like a leaf or blend into the bark of a tree to hide from predators. Anothermethod is chemical defense, where the butterfly has evolved to have toxic chemicals inits body. These species of butterfly are often brightly colored, and predators have learnedover time to associate their bright color with the bad taste of the chemicals.
