Moth
Moths are a paraphyletic group of insects that includes all members of the order Lepidoptera that are not butterflies, with moths making up the vast majority of the order. There are thought to be approximately 160,000 species of moth, many of which have yet to be described. Most species of moth are nocturnal, but there are also crepuscular and diurnal species. Differences between butterflies and moths While the butterflies form a monophyletic group, the moths, comprising the rest of the Lepidoptera, do not. Many attempts have been made to group the superfamilies of the Lepidoptera into natural groups, most of which fail because one of the two groups is not monophyletic: Microlepidoptera and Macrolepidoptera, Heterocera and Rhopalocera, Jugatae and Frenatae, Monotrysia and Ditrysia.Scoble, MJ 1995.

Geometridae
The geometer moths are moths belonging to the family Geometridae of the insect order Lepidoptera, the moths and butterflies. Their scientific name derives from the Ancient Greek ''geo'' γεω (derivative form of or "the earth"), and ''metron'' "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. A very large family, it has around 23,000 species of moths described, and over 1400 species from six subfamilies indigenous to North America alone. A well-known member is the peppered moth, ''Biston betularia'', which has been subject of numerous studies in population genetics. Several other geometer moths are notorious pests. Adults Many geometrids have slender abdomens and broad wings which are usually held flat with the hindwings visible. As such, they appear rather butterfly-like, but in most respects they are typical moths; the majority fly at night, they possess a frenulum to link the wings, and th ...

Transcaucasia
The South Caucasus, also known as Transcaucasia or the Transcaucasus, is a geographical region on the border of Eastern Europe and Western Asia, straddling the southern Caucasus Mountains. The South Caucasus roughly corresponds to modern Armenia, Georgia, and Azerbaijan, which are sometimes collectively known as the Caucasian States. The total area of these countries measures about . The South Caucasus and the North Caucasus together comprise the larger Caucasus geographical region that divides Eurasia. Geography The South Caucasus spans the southern portion of the Caucasus Mountains and their lowlands, straddling the border between the continents of Europe and Asia, and extending southwards from the southern part of the Main Caucasian Range of southwestern Russia to the Turkish and Armenian borders, and from the Black Sea in the west to the Caspian Sea coast of Iran in the east. The area includes the southern part of the Greater Caucasus mountain range, the entire Lesser C ...

Eupithecia
''Eupithecia'' is a large genus of moths of the family Geometridae. There are hundreds of described species, found in all parts of the world (with 45 in the British Isles alone), and new species are discovered on a regular basis. ''Eupithecia'' species form the bulk of the group commonly known as pugs. They are generally small with muted colours and specific identification can be difficult. As a group they are easily identified by their narrow wings held flat at 90° to the body with the hindwings almost hidden behind the forewings. The larvae of many species feed on the flowers and seeds of their food plants rather than the foliage. Many species have a very specific food plant. Some Hawaiian ''Eupithecia'' as caterpillars are predators of other insects ('' E. orichloris'', '' E. staurophragma'', '' E. scoriodes''). They mimic twigs but when sensitive hairs on their backs are triggered, they quickly grab the insects touching them. The defensive behavior of snapping may have pr ...
