The White-pinion Spotted (Lomographa bimaculata) is a geometer moth species (family Geometridae).
 It belongs to the large geometer moth subfamily Ennominae, and therein to the tribe Baptini.
 It is – under its junior synonym – the type species of its genus "Lomographa".
 It is also (under its original name "Phalaena bimaculata") the type species of "Bapta", a junior objective synonym of "Lomographa" and the namesake of the Baptini.
Bhutan ( ; འབྲུག་ཡུལ་ "druk yul "), officially the Kingdom of Bhutan (འབྲུག་རྒྱལ་ཁབ་ "druk gyal khap "), is a landlocked country in South Asia.
 Located in the Eastern Himalayas, it is bordered by Tibet Autonomous Region in the north, India in the south, the Sikkim state of India and the Chumbi Valley of Tibet in the west, and Arunachal Pradesh state of India in the east.
 Bhutan is geopolitically in South Asia and is the region's second least populous nation after the Maldives.
 Thimphu is its capital and largest city, while Phuntsholing is its financial center.
Diaphania indica, the cucumber moth or cotton caterpillar, is a widespread but mainly Old World moth species.
 It belongs to the grass moth family, and therein to the large subfamily Spilomelinae.
 This moth occurs in many tropical and subtropical regions outside the Americas, though it is native to southern Asia; it is occasionally a significant pest of cucurbits and some other plants.
Erechthias simulans is a fungus moth species (family Tineidae).
 It is here considered to belong to the somewhat controversial type genus of its subfamily Erechthiinae, though even fairly recently some authors have proposed to retain other genera such as "Decadarchis" separate from "Erechthias".
 "Decadarchis", with "E. simulans" as type species (under the obsolete name "Decadarchis melanastra"), would in fact contain this moth and its closest relatives, regardless whether it is recognized as full genus or as subgenus.
 These relatives are generally held to be a group of mainly Polynesian species.
 "E. simulans" has also been mistaken for a species of the closely related genus "Comodica"; while the delimitation of this versus "Erechthias/Decadarchis" is not universally agreed upon, "E. simulans" is not included in "Comodica" anymore by modern authors.
The Marion flightless moth or Subantarctic caterpillar ("Pringleophaga marioni") is a moth of the Tineidae family.
 It is endemic to Marion Island.
 Beside being unable to fly, this moth species is notable because of its ability to resist temperatures that are so low, that they would kill most other species.
The pandanus leaf perforator or pandanus hole-cutter moth (Trissodoris honorariella) is a small cosmet moth species (family Cosmopterigidae).
 It belongs to subfamily Cosmopteriginae and is the type species of the genus "Trissodoris".
 Baron Thomas Walsingham in 1907 had specimens from both ends of the species' range – New Guinea and the Pitcairn Island – which he described as separate species "Stagmatophora honorariella" and "S. quadrifasciata" in the same work.
 But his mistake was soon recognized, and when Edward Meyrick established the genus "Trissodoris" in 1914, he chose the former name to be valid.
The hemlock moth (Agonopterix alstroemeriana), also known as the defoliating hemlock moth or poison hemlock moth, is a moth species of the family Depressariidae.
 Of Palaearctic origin, it was first found in North America in 1973 when it was accidentally introduced.
Ennominae is the largest subfamily of the geometer moth family (Geometridae) with some 9,700 described species in 1,100 genera.
 They are usually a fairly small moth species, though some (such as the Peppered Moth) grow to be considerably large.
 This subfamily has a global distribution.
 It includes some species that are notorious defoliating pests.
Lepidogma rufescens is a species of snout moth in the genus "Lepidogma".
 It was described by Hampson in 1896, and is known from Bhutan.
Grotellaforma lactea is a species of moth in the genus Grotellaforma, of the family Noctuidae.
 This moth species is found in North America, including California and Arizona, its type locations.
