Reading 2 Moths and butterflies are common insect that live in your garden. They don’t have skeletons inside their bodies as we have. Their ‘skeletons' are on the outside-they don't have backbones, knee-bones or toe-bones,but instead have a soft body on the inside with a type of hard protective shell. Butterflies can laste things through their feet. They often stomp up and down on a leaf，testing and tasting it to see if it is a good pIace to lay their eggs. Some butterflies lay their eggs all together, and others lay theirs in scattered bunches which keeps the eggs safer from enemies that might enjoy snacking on them. Butterflies and moths have a long hollow tube，just like a straw, that they use to suck up their food (flower nectar) The tube is called a proboscis and it can be curled away neatly when it is not being used. The longest proboscis belongs to Darwin’s hawkmoth. It is about 35 cm long and the moth ne^ds it to reach the nectar at the bottom of the deep flowers it feeds on. Butterflies and moths have been fluttering about the skies for 140 million years. Unfortunately, modem times have seen many beautiful species become extinct. They have died out because forests have been cut and their homes there have been lost. 【題組】29. Why do butterflies sometimes stomp up and down on leaves?
