我突然被地上一小块一小块的土吸引了,细看是绿色的,才知道这不是土,再往上看才看见了原来是它的屎几天后,蛹变成了成虫,蝴蝶就从裂开的蛹壳里出来。这时它的翅膀是折叠着的。你将纱布取下,把蝴蝶从瓶里放出,待它身子干燥后就会展翅飞舞,在鲜花丛中游戏。 成虫完成产卵任务后便死去,卵经过发育又孵出毛毛虫。 毛毛虫的一生,要经过卵、幼虫、蛹、成虫四个阶段。其中幼虫阶段对人类有害,要吃作物的叶子。但成虫蝴蝶或蛾大多数却能帮助植物传播花粉,对人类也有益处。 毛毛虫的腿多达数条分布在身体的左右两侧,常见血液的颜色有绿色及红棕色,颜色不定。 看到这,我后悔丢垃圾桶了,应该养起来让它变成漂亮的燕尾蝶。 下面是抄来的英文解释。 Caterpillars are the larval stage of members of the order Lepidoptera (the insect order comprising butterflies and moths). As with most common names, the application of the word is arbitrary, since the larvae of sawflies are commonly called caterpillars as well. Both lepidopteran and symphytan larvae have eruciform body shapes. Caterpillars of most species are herbivorous (folivorous), but not all; some (about 1%) are insectivorous, even cannibalistic. Some feed on other animal products; for example, clothes moths feed on wool, and horn moths feed on the hooves and horns of dead ungulates. Caterpillars are typically voracious feeders and many of them are among the most serious of agricultural pests. In fact many moth species are best known in their caterpillar stages because of the damage they cause to fruits and other agricultural produce, whereas the moths are obscure and do no direct harm. Conversely, various species of caterpillar are valued as sources of silk, as human or animal food, or for biological control of pest plants. Caterpillars have been called "eating machines", and eat leaves voraciously. Most species shed their skin four or five times as their bodies grow, and they eventually enter a pupal stage before becoming adults.[23] Caterpillars grow very quickly; for instance, a tobacco hornworm will increase its weight ten-thousandfold in less than twenty days. An adaptation that enables them to eat so much is a mechanism in a specialized midgut that quickly transports ions to the lumen (midgut cavity), to keep the potassium level higher in the midgut cavity than in the hemolymph. Most caterpillars are solely herbivorous. Many are restricted to feeding on one species of plant, while others are polyphagous. Some, including the clothes moth, feed on detritus. Some are predatory, and may prey on other species of caterpillars (e.g. Hawaiian Eupithecia). Others feed on eggs of other insects, aphids, scale insects, or ant larvae. A few are parasitic on cicadas or leaf hoppers (Epipyropidae). Some Hawaiian caterpillars (Hyposmocoma molluscivora) use silk traps to capture snails. Many caterpillars are nocturnal. For example, the "cutworms" (of the family Noctuidae) hide at the base of plants during the day and only feed at night. Others, such as gypsy moth (Lymantria dispar) larvae, change their activity patterns depending on density and larval stage, with more diurnal feeding in early instars and high densities.
