A Butterfly’s Lesson ”One day, asmall openingappeared on acocoon; a mansat and watchedfor the butterflyfor several hoursas it struggled toforce its bodythrough that littlehole.Then, it seems to stop making any progress.It appeared as if it had gotten as far as it could and it could not go any further.So the man decided to help the butterfly: he took a pair of scissors and opened the cocoon.The butterfly then emerged easily.But it had a withered body, it was tiny and shrivelled wings.The man continued to watch because he expected that, at any moment, the wings would open, enlarge and expand, to be able to support the butterfly’s body, and become firm.Neither happened!In fact, the butterfly spent the rest of its life crawling around with a withered body and shrivelled wings. It never was able to fly.What the man, in his kindness and his goodwill did not understand was that the restricting cocoon and the struggle required for the butterfly to get through the tiny opening, were God’s way of forcing fluid from the body of the butterfly into its wings, so that it would be ready for flight once it achieved its freedom from the cocoon.Sometimes, struggles are exactly what we need in our life.If God allowed us to go through our life without any obstacles, it would cripple us. We would not be as strong as we could have been. Never been able to fly.I asked for Strength... And God gave me difficulties to make me strong.Iasked for Wisdom... And God gave me Problems to solve.I asked for prosperity...And God gave me a Brain and Brawn to work.I asked for Courage….. And God gave me obstacles to overcome.I asked for Love...And God gave me Troubled people to help.I asked for Favors... And God gave me Opportunities.“I received nothing I wanted...But I received everything I needed."Execução: Leandro ValdirTraducción: Fidelia GarcíaLive life without fear, confront all obstacles and evince that you can overcome them. Send this message to your friends and show them how much you care. Send it to anybody that you consider a FRIEND, even if this means to send it to the same person that conveyed it to you. If this message returns to you, you can be sure that your circle of friendship is made out of true friends.。

ButterflyButterfly有关于蝴蝶的研究1.蝴蝶的历史课2.蝴蝶也曾花样

绢蝶科
本科与凤蝶科很接近，多数为中等大小，白色或蜡黄色。绢蝶科触角短，端部膨大成棒状；下唇须短；体被毛。翅近圆形，翅面鳞片稀少（鳞片种子状），半透明，有黑色，红色世黄色的斑纹，斑纹多成环状。前翅 R脉只有4条，A脉2条，无臀横脉；后翅无尾突，A脉1条。雌性腹部末端在交配后产生各种形状的角质臀袋，经避免再次的交配。本科种类均产于高山上，耐寒力强，有的在雪线上下紧贴地面飞翔，行动缓慢，容易捕捉。仅少数种类分布在低海拔的山顶。均一年1代。
蝴蝶的生活习性
取食
蝶类幼虫咬破卵壳孵化外出以后，有些种类略事休息，就直接啃食寄主植物；有些种类（例如红眼竹弄蝶）则先行取食卵壳，然后取食植物；更有一些种类还需取食每次蜕皮时所蜕下来的旧表皮，例如菜粉蝶和斑缘豆粉蝶等。
蝶类幼虫的取食对象，因虫种而各有不同，大多数幼虫嗜食叶片；有些种类，例如花粉蝶、橙斑襟粉蝶等嗜食花蕾；还有一些种类蛀食嫩荚或幼果，例如豆荚灰蝶蛀食嫩豆荚，栀子灰蝶蛀食栀子幼果。此外在灰蝶科中，有少数种类的幼虫是肉食性的，例如，蚧灰蝶嗜食咖啡蚧，竹蚜灰蝶专以竹蚜为食，这种肉食性的种类在蝶类中是并不多见的益虫。
蝴蝶趣闻
世界上最大的蝴蝶世界上最大的蝴蝶翅膀展开有
30cm，产于太平洋西南部的所罗门群岛和巴布亚新几内亚。他的名字叫大鸟翼蝶。据资料，最初人们是在一个密林中发现的，它在树梢上飞来飞去，很不容易采捕，后来还是用弓箭将它射落。
世界上翅形最长的蝴蝶
长翅大凤蝶是非洲的代表凤蝶，它在翅形长度常超过 20～23cm ，比大鸟翼蝶的雄蝶还长。成虫体内有剧毒，据说可毒死6只猫。
生活在最高地方的蝴蝶
我国的帕米尔高原最高处有7000多米，登山健儿曾在海拔6000米左右的冰川裂缝里看到过一种紫酱色的小灰蝶。

蝴蝶的生长发育变化过程-PPT课件

4．蛾类躯干部被毛一般都很浓密，就像天蛾科的蛾类飞行期间很容易与蜂鸟混为一谈。 5．大多数蛾类的腹面后翅根部是平滑的，弧度很小，这跟蛾类在夜间飞行速度慢有关。 6．蛾的蛹有茧。例如，蚕丝就是从家蚕的茧提取的。
蝴蝶翅膀上的鳞片不仅能使蝴蝶艳丽无比、还像是蝴蝶的一件雨衣。因为蝴蝶翅膀的鳞片里含有丰富的脂肪，能把蝴蝶保护起来
蝴即所蝶使以也下能小飞雨行时，
…
形态特征触角端部加粗，翅宽大，停歇时翅竖立于背上。最大的是澳大利亚的一种蝴蝶，展翅可达26厘米；最小的是灰蝶，展翅只有15毫米。蝶类触角为棒形，触角端部各节粗壮，成棒锤状。口器是下口式；足是步行足；翅是鳞翅；属于全变态。体和翅被扁平的鳞状毛覆盖。腹部瘦长。蝶类白天活动。
蝴蝶、蛾、弄蝶都被归类为鳞翅目
蝶与蛾的区别
与蛾相似之点是在翅、体和足上均覆以一触即落的尘状鳞片。与蛾相异之处是蝴蝶白天活动、色泽鲜豔或图纹醒目。两者最显著的区别大概是蝶的触角呈棒状，休止时翅折叠与背垂直。
蝶的特点 1．多数蝶类翅膀正面的鳞粉色泽亮丽，翅表面不被毛绒。少数蛱蝶科的蝶类后翅根部被有较明显的毛绒。 2．多数蝶类有顶端膨大的棒状触角。 3．蝶类四翅合拢竖立于背上休息的方式。 4．蝶类躯干上被毛稀疏（需与蛾类比较）。
5．蝶类腹面可见的后翅根部呈弧形（贴接式），无翅缰。有助于飞行的速度提升，是因为蝶类在白天活动普遍飞行速度快于蛾类。 6．蝶的蛹赤裸，无茧。 7. 蝴蝶的活动时间严格定义在白天。[
飞蛾的特点
1. 蛾子不分昼夜地飞，大多数都是棕色或者黑色，很少有几种颜色与蝴蝶一样鲜艳。 2．多数蛾类触角顶端呈针尖样弯曲或整个触角呈羽毛状，少数蛾类（天蛾科、斑蛾科）由于白天活动所以触角与蝶类相似。 3．蛾类多数都是将四翅平铺休息。

butterfly 蝴蝶 ppt

1.Egg rva, known as a caterpillar
3.Pupa (chrysalis)
4.Adult butterfly (imago)
Butterfly eggs consist of a hard-ridged outer layer of shell, called the chorion(绒毛膜）. This is lined with a thin coating of wax（蜡） which prevents the egg from drying out before the larva has had time to fully develop. Each egg contains a number of tiny funnel-shaped openings at one end, called micropyles（卵孔）（to allow sperm （精子）to enter and fertilize the egg）. Butterfly eggs are fixed to a leaf with a special glue which hardens rapidly and will deform the shape of the egg.
The pupal transformation into a butterfly through metamorphosis（变态） has held great appeal to mankind. To transform from the miniature wings visible on the outside of the pupa into large structures usable for flight, the pupal wings undergo rapid mitosis（有丝分裂） and absorb a great deal of nutrients.

中华虎凤蝶中华虎凤蝶翅膀的基色黄，前翅外缘有宽的黑带，翅面有很多黑色的短ห้องสมุดไป่ตู้犹如虎皮。后翅外缘波形，尾突短，外缘的黑带上镶嵌有弯月形黄斑，黑带的中间嵌有蓝色斑点，最里面有一列弯月状红斑。（见上右图）它是中国特有珍稀种类，作为中国昆虫学会蝴蝶分会的会徽图案，属国家二级保护动物
三尾褐凤蝶三尾褐凤蝶有多个名字：华西褐凤蝶、三尾凤蝶等，虽然叫做凤蝶，但它不是凤蝶科的成员，而是娟蝶科的种类。身体和翅黑色，前翅有8条黄色横纹，第三、第五条短，而第六第七条在后方并连；它的后翅狭长，外缘波状，后端有明显的三个尾突，最外缘有五个橙色短斑，靠里约有八个蓝色斑，往里接着有一大的红色横斑，其余翅面分布很多纵横黄条纹。（见下左图）三尾褐凤蝶是高山种类，生活在海拔2000米以上的山区。国内分布于云南、四川、陕西、西藏，属国家二级保护动物。
蝶，通称为“蝴蝶”，全世界大约有14000余种，大部分分布在美洲，尤其在亚马逊河流域品种最多，在世界其他地区除了南北极寒冷地带以外，都有分布，在亚洲台湾也以蝴蝶品种繁多著名。蝴蝶一般色彩鲜艳，翅膀和身体有各种花斑，头部有一对棒状或锤状触角（这是和蛾类的主要区别，蛾的触角形状多样）。最大的蝴蝶展翅可达24厘米，最小的只有1.6厘米。大型蝴蝶非常引人注意，专门有人收集各种蝴蝶标本，在美洲“观蝶”迁徙和“观鸟” 一样，成为一种的活动，吸引许多人参加。有许多种类的蝴蝶是农业和果木的主要害虫。
阿波罗娟蝶娟蝶以秀丽清雅而备受人们喜爱。翅白色或略带淡黄色，半透明，前翅有几个大黑斑，后翅有2个大而鲜明的红斑，红斑中心白色，有黑边，使娟蝶更增添了娇美。娟蝶生活在高山，有很强的耐寒能力，有的在雪线上活动，紧贴着地面飞翔，但行动缓慢。阿波罗娟蝶（见上右图）是国产10多种娟蝶中较珍贵的种类，仅分布于新疆。属于国家二级保护动物。
