Stick insects can also be commonly called bug sticks, stick bugs and walking sticks. It's estimated there are over 3,000 different species of Stick insects in the Phasmatodea order. Stick insects have a head, thorax and abdomen 和爸爸对稿子ing 第一次讲竹节虫 给另一组小朋友讲，带上了小小讲解员的绶带仪式感很强！ Stick insect species are commonly black, brown and green or multiple variations of these colors. The size of a Stick insect varies by species. Smaller species are around 0.5 inch long, while large species can grow to be longer than 12 inches. There are three stages of the Stick insect's lifecycle, and they are egg, nymph and adult. The average lifespan of a Stick insect is between one and two years. Stick insects are herbivores and use their strong mandibles to eat leaves off a tree. Stick insects use camouflage as a defense against predators. They can mimic plants and are very effective at replicating the form of sticks and leaves. Stick insects can regenerate their limbs if they are broken off. They can sacrifice a limb to escape from a predator. The Phobaeticus chani is the longest Stick insect in the world. With its legs fully extended, it can reach up to 22 inches in length. 🍡butterflyThe life of a butterfly, for example, is just a graceful gesture: and yet, in that its love lines s is complete and perfectly rounded in itself. 🍡butterfly It takes about 7-10 days for an egg to develop into an adult mosquito. 虫卵发育成成虫大概需要7-10天。 Life stages of Aedes aegypti and Aedes albopictus mosquitoes 埃及伊蚊和白纹伊蚊的生活史 Eggs 卵 ••Adult, female mosquitoes lay eggs on the inner, wet walls of containers with water, above the waterline. ••Eggs stick to container walls like glue. They can survive drying out for up to 8 months. Mosquito eggs can even survive a winter in the southern United States. ••Mosquitoes only need a small amount of water to lay eggs. Bowls, cups, fountains, tires, barrels, vases, and any other container storing water make a great “nursery.” Eggs look like black dirt. 虫卵看起来像黑色的泥块。 ••雌性成蚊在盛水容器内壁的水平线上产卵。 ••卵像胶水一样粘在容器壁上。它们在干燥环境下可以存活长达8个月。在美国南部地区，蚊卵甚至可以存活过冬。 ••蚊子只需要很少量的水就可产卵。碗、杯、喷泉、轮胎、桶、花瓶以及任何可以存储水的容器，都是很好的“温床”。 Larva 幼虫 ••Larvae live in the water. They emerge from mosquito eggs. This happens when water (from rain or a sprinkler) covers the eggs. ••Larvae can be seen in the water. They are very active and are often called “wigglers.” Larvae in the water. 水中的幼虫（孑孓）。 幼虫在水中生活。它们由卵孵化而成。只要有水（雨水或喷洒的水）覆盖虫卵时就可孵化。 幼虫在水中可见。它们非常活跃，常被称为“孑孓”。 Pupa 蛹 ••Pupae live in the water. An adult mosquito emerges fromthe pupa and flies away. Pupae in the water. 水中的蛹。 蛹在水中生活。蛹孵化成成蚊后飞走。 An adult mosquito emerges from a pupae. 蛹蜕化为成虫 Adult 成虫 • Adult female mosquitoes bite people and animals.Mosquitoes need blood to produce eggs. •• After feeding, female mosquitoes look for water sources tolay eggs. •• Aedes aegypti and Aedes albopictus don’t fly long distances.In its lifetime, a mosquito will only fly within a few blocks. •• Aedes aegypti mosquitoes prefer to live near and bitepeople. •• Because Aedes albopictus bite people and animals, they canlive near homes or in neighboring woods. •• Mosquitoes live inside and outside. An adult mosquito bites a person. 成蚊在叮咬人。 ••雌性成蚊叮咬人和动物。蚊子需要吸血才可产卵。 ••吸血后，雌蚊寻找水源产卵。 ••埃及伊蚊和白纹伊蚊飞得并不远。一生中，蚊子只会在几个街道内飞行。 ••埃及伊蚊喜欢住在人类附近，叮咬人。 ••由于埃及伊蚊要叮咬人和动物，它们会在住家附近或邻近的树林中生活。 ••蚊子在室内和室外生活。 🍡fly 🍡lady bug 🍡fire fly 　　🍡lazard Most lizards hatch out from the eggs. Some Lizards are small, and some are very big. Lizards are cold-blooded animals that have eyelids and a tail. These reptiles usually have four legs, and some lizards have no legs. There are about 2,500 different species of lizards. Most lizards live in trees or on the ground; only a few live in the water. Lizards like to sun themselves to increase their body temperature. They also vary in color. Ground and tree lizards are usually brightly-colored. Desert lizards are usually sand-colored. Chameleons can change their skin color to match their surroundings. When a predator is attacking, the lizard can break off its tail to escape. Later, the lizard will regrow the tail. Most lizards eat insects. Some eat bigger animals, like birds. The lizard has a large mouth,large eyes... The Komodo dragon is the world's biggest lizard. The Komodo dragon is a meat-eater. It can run fast,climb the trees and swim. when it bites the animals, the Komodo dragon injects the animals with a venom that will make the animals dead. 见着活的蜥蜴啦 🍡尺蠖geometer 尺蠖(chihuo)节肢动物门昆虫纲鳞翅目尺蛾科昆虫的统称。 图：尺蠖幼虫 幼虫身体细长，行动时一屈一伸像个拱桥，休息时，身体能斜向伸直如枝状。完全变态。成虫翅大，体细长有短毛，触角丝状或羽状，称为"尺蛾"。全世界约有12000种，我国约有43种。幼虫为害果树，茶树、桑树、棉花和林木等。如茶尺蠖的幼虫食害叶片，严重时造成光秃现象。静止时，常用腹足和尾足抓住茶枝，使虫体向前斜伸，颇像一个枯枝，受惊时即吐丝下垂;又如枣尺蠖的幼虫，不仅食害枣树，酸枣的叶片，并食嫩芽、花蕾。雌成虫无翅，雄成虫全体灰褐色，前翅有褐色波纹2条。我国南北各地最常见的桑尺蠖，其幼虫常作为"拟态"的典型代表。 图：尺蛾 生活史及习性: 每年发生1代，以蛹在树下土中8~10厘米处越冬。翌年3月下旬至4月上旬羽化。雌蛾出土后，当晚爬至树上交尾，卵多产在树皮缝内，卵块上覆盖有雌蛾尾端绒毛。4月中下旬枣树发芽，幼虫孵化为害，为害盛期在5月份。5月下旬至6月上旬幼虫先后老熟，入土化蛹越夏越冬。 天敌: 有枣尺蠖肿跗姬蜂和寄生蝇 cankerworm, name for two destructive inchworms, or larvae of geometrid moths. the striped, green caterpillar of any of several geometrid moths: a foliage pest of various fruit and shade trees, as Paleacrita vernata (spring cankerworm) and Alsophila pometaria (fall cankerworm). The spring cankerworm (Paleacrita vernata) and the fall cankerworm (Alsophila pometaria) are named for the seasons at which the adults emerge from underground pupation. The spring cankerworm larva overwinters as a pupa, the fall cankerworm as an egg. The larvae, dark green to brown and about 1 in. (2.5 cm) long, feed on the leaves of orchard and shade trees. The spring cankerworm has two pairs of posterior ages (prolegs); the fall cankerworm has three. The wingless female lays her eggs on the bark, and one control method is the placing of bands of sticky paper around the tree trunks to trap the females before laying. When alarmed, cankerworms drop and hang suspended in midair at the end of a long silken thread secreted from their mouths; they ascend this thread after the danger has passed. The English sparrow was originally introduced in the United States to combat the spring cankerworm. Cankerworms are classified in the phylum Arthropoda, class Insecta, order Lepidoptera, family Geometridae. For control methods see bulletins of the U.S. Dept. of Agriculture. 图：parts of a cankerworm 🍡独角仙1 独角仙的简单介绍 2min 英文名来源—犀牛+甲虫 特点：两个角 Rhinoceros beetle------Rhinoceros Rhino Beetle Rhino 2 成虫和幼虫主要部分， 英文看图讲解 2min 3 life cycle 英文看图讲解 2min 4、角的作用——fight 1min 讲解图片如下： 1、Rhinoceros Rhinoceros beetle 2、parts Adult beetle key parts：two horns（head horn/pronotal horn），elytron（鞘翅），6 legs，2 antenna，3parts Larva parts： 6legs，spiracles（通气孔/气门） 3、life cycle Real pictures Larva Pupa Male adult Female adult 4、horns for fight 🍡叶樇：竹节虫，又称䗛（拼音：xiū，）leaf insects是节肢动物门昆虫纲竹节虫目（又称䗛）的总称。草食性的昆虫，以善于拟态成树枝或树叶著称，可以躲过天敌。全世界约有2,500种。 体型修长，呈圆筒形，棒状或枝状；少数种类扁平如叶。复眼发达，单眼通常退化。翅膀通常退化；如有翅膀，前翅通常小于后翅。不完全变态，陆栖，植食性昆虫。多数分布于热带。 叶虫，是拟态和保护色都十分巧妙的珍稀昆虫。不仅能够模仿树叶边缘被咬过的破损和干枯，不但可以将身体的纹脉伪装成叶子的叶脉，六条腿和身体边缘居然能像枯叶一样“枯萎”。甚至还会惟妙惟肖地模仿树叶迎风摇曳的样子。在爬行时，他会来回摇晃身体，就像是被风吹起的树叶，更令人惊奇的是，一些叶虫居然在身体边缘“伪造”被咬过的痕迹，用以迷惑敌人。 拟态是昆虫提高自身生存能力的重要手段，很多昆虫都深谙伪装和模仿之道。有一种叫叶樇的昆虫就是拟态高手，它的前中足都呈片状，扁平的身体边缘也像是被昆虫啃食后残缺的树叶。叶樇不但擅长伪装外表，还有着非凡的表演技巧，他们爬行时来回摇摆着身体，像极了在风中舞动的树叶。 🍡叶螽：（学名：Acanthoplus discoidalis）属直翅目螽斯科，体型硕大，不能飞，身长约30-50mm，体色多样。最让人惊讶的是它们全身带刺，遇到危险时会喷射难闻的毒液以减小被捕食的几率，是直翅目昆虫的“升级版”。该昆虫为肉食性，甚至自相残杀。而且，它们适应力极强，能在各种环境下生存，如：沙漠、雨林和平原等。主要分布于非洲的大部分地区。 特征： 成年披甲树螽硕大无比，不能飞，身长约30-50毫米。背板及四肢蓝色、褐绿色、紫色或棕黄色，腹部圆鼓，呈灰色，有黑色斑点；无翅，靠摩擦后腿发声；四肢粗壮，外壳坚硬，全身带硬刺，遇到紧急情况时会分泌黄绿色色毒液（体内一种血淋巴），辛辣并且很难闻，关键时刻还会喷血。雌性体型略大于雄性，且产卵器短粗，有刺。 生活习性： 食物：比较喜欢桑科植物。例如黄金榕，无花果。牛筋藤属。其经常生活于树上，雄性叫声响亮，甚至可以超过一般的蝉。 [2] 终年生活在版纳雨林区，通常栖息在较高的树上。若虫喜欢聚集在一起生活。吃嫩叶。雄虫夜间在树顶发出异常响亮的鸣声。很远都能清楚的听到。只要听过一次都终身难忘。 🍡枯叶蛾lasiocampidea，枯叶蝶kllima inchus，蝗虫locust 爸爸在认真给小盆友们作讲解哦！ 胆大的小盆友认领了这只枯叶蝶回家～ 正好我们带了捕虫工具～ 昆虫作为动物世界里的弱势群体，为了躲避天敌的猎捕和攻击，或更方便捕食其他昆虫，经过漫长演化，具备了一些特殊的技能。它们会通过自身的保护色和拟态行为，把自己巧妙地伪装起来，也只有善于伪装和蒙骗天敌，才能求得生存，因而具备这种能力，对维持生物个体生存和其种族延续都非常重要。 未完待续…感谢关注！
