Lists of Lepidoptera by region

[2] In the Himalayas, various Apollo species such as Parnassius epaphus, have been recorded to occur up to an altitude of 6,000 meters above sea level.

[3]: 221 Some lepidopteran species exhibit symbiotic, phoretic, or parasitic life-styles, inhabiting the bodies of organisms rather than the environment.

Coprophagous pyralid moth species, called sloth moths, such as Bradipodicola hahneli and Cryptoses choloepi, are unusual in that they are exclusively found inhabiting the fur of sloths, mammals found in Central and South America.

[4][5] Two species of Tinea moths have been recorded as feeding on horny tissue and have been bred from the horns of cattle.

Many species have been recorded as breeding in natural materials or refuse such as owl pellets, bat caves, honey-combs or diseased fruit.
