Attacus atlas - one of the world's largest moths. They can have wingspans of up to 30 cm.

Born without the ability to eat, they live on the reserves they store as caterpillars.

 

Wow

 

my favorite more then twice as large as any other breed in their species would have to be those squirrels they have over in india.
for smaller then would have to be geoffery's cat and phenic fox. among butterflys, there is a blue winged that's pretty good size and making a comeback,
right over there in GB.

 

One of these dudes was recently captured in Washington State.
