Which is the biggest butterfly<br />

Well, for a start she’s female and she’s named after a<br />

queen … the Queen Alexandra birdwing. This rare<br />

and poisonous beauty has a wingspan of up to 28 cm<br />

(11 in.), with pale markings on a dark chocolate-brown<br />

background and a bright yellow abdomen. Both<br />

the males and the females fly high in<br />

the rainforest<br />

canopy of Papua<br />

New Guinea.<br />

The Queen<br />

Alexandra birdwing<br />

is one of the world’s<br />

biggest butterflies.<br />

Which is the largest moth<br />

The atlas moth is a truly impressive sight and has the<br />

largest wing area of any moth in the world. It lives in<br />

the jungles of Malaysia, and uses the large white ‘eye<br />

spots’ on its beautiful ruby-coloured wings to warn off<br />

predators. Despite its defence camouflage, the atlas<br />

moth has a sad tale to tell. While the atlas<br />

caterpillar munches as<br />

much as it can in<br />

order to develop into<br />

this mammoth moth,<br />

the atlas moth itself has no<br />

stomach. This means that it<br />

cannot take in food, and so<br />

lives for only around a day.<br />

FACT FILE<br />

An atlas moth.<br />

Keep a look out for butterflies basking in the<br />

sunshine on chilly days. They do this because<br />

their wing muscles won’t work properly if they<br />

get too cold, which prevents them from flying.<br />

Their optimum body temperature is around 28˚C.
