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, and metron μέτρον "measure" in reference to the way their larvae, or inchworms, appear to measure the earth as they move along in a looping fashion. Geometridae is a very large family, containing around 23,000 described species; over 1400 species from six subfamilies are indigenous to North America alone. A well-known member is the peppered moth, Biston betularia, which has been the subject of numerous studies in population genetics. Several other geometer moths are notorious pests.
The latticed heath is a moth of the family Geometridae, belonging to the subfamily Ennominae, placed in the tribe Macariini. The genus was erected by Carl Linnaeus in his 1758 10th edition of Systema Naturae.
The scalloped hazel is a moth of the family Geometridae. The species was first described by Carl Alexander Clerck in 1759.
The Macariini are a tribe of geometer moths in the subfamily Ennominae. Though they share many traits with the Sterrhinae, this is probably plesiomorphic rather than indicative of a close relationship, and DNA sequence data points to the Boarmiini as particularly close relatives of the Macariini. All things considered, this tribe might still resemble the first Ennominae more than any other living lineage in the subfamily.
The Bistonini are a tribe of geometer moths in subfamily Ennominae. As numerous ennomine genera have not yet been assigned to a tribe, the genus list is preliminary. In addition, the entire tribe is sometimes merged into a much-expanded Boarmiini. In other treatments, the Erannini are included in the present group.
The Ennomini are a tribe of geometer moths in the Ennominae subfamily. They are large-bodied and rather nondescript Ennominae, overall showing many similarities to the closely related Azelinini and Nacophorini.
The Ourapterygini are one of the large tribes of geometer moths in the subfamily Ennominae. The tribe was described by Charles Théophile Bruand d'Uzelle in 1846. They are particularly plentiful in the Neotropics. Ourapterygini are generally held to be the youngest tribe of their subfamily, and at least seasonally have characteristic apomorphic asymmetrical processes of the anellus.
The Abraxini are a tribe of geometer moths in the subfamily Ennominae. Here, the Cassymini are considered a specialized offshoot of the Abraxini and merged therein; some authors consider them a distinct tribe however.
Larentiinae is a subfamily of moths containing roughly 5,800 species that occur mostly in the temperate regions of the world. They are generally considered a subfamily of the geometer moth family (Geometridae) and are divided into a few large or good-sized tribes, and numerous very small or even monotypic ones which might not always be valid. Well-known members are the "pug moths" of the Eupitheciini and the "carpets", mainly of the Cidariini and Xanthorhoini. The subfamily was described by Philogène Auguste Joseph Duponchel in 1845.
The Boarmiini are a large tribe of geometer moths in the Ennominae subfamily.
The Baltic region is home to the largest known deposit of amber, called Baltic amber or succinite. It was produced sometime during the Eocene epoch, but exactly when is controversial. It has been estimated that these forests created more than 100,000 tons of amber. Today, more than 90% of the world's amber comes from Kaliningrad Oblast of Russia. It is a major source of income for the region; the local Kaliningrad Amber Combine extracted 250 tonnes of it in 2014 and 400 tonnes in 2015.
The Nacophorini are one of the smaller tribes of geometer moths in the subfamily Ennominae. They are the most diverse Ennominae of Australia and are widespread in the Americas. If the African genera tentatively placed herein indeed belong here, the distribution of the Nacophorini is distinctly Gondwanan, with their probable origin either of Australia, South America or even Antarctica. In Eurasia, they are rare by comparison.
Idaea humiliata, the Isle of Wight wave, is a moth of the family Geometridae. It is found in Europe and Western Asia.
The Azelinini are a tribe of geometer moths in the subfamily Ennominae, with many species in the Southern Hemisphere, particularly in South America. Several species are found in North America as well. These stocky geometer moths seem to be closely related to other robust tribes, such as the Campaeini, Ennomini, Lithinini and Nacophorini – all of which might warrant to be subsumed in the Ennomini – the genus Odontopera, and perhaps the Caberini and Colotoini. The tribe was first described by William Trowbridge Merrifield Forbes in 1948.
Drepanogynis is a genus in the geometer moth family (Geometridae). Long considered to hold about 5 dozen species, this number has been doubled after the last major revision. They are stout-bodied and hairy by geometer moth standards, usually have pale hindwings and rest with their wings angled upwards like a roof, as Nacophorini do. The genus is by and large restricted to Africa south of the Equator, with most species occurring in southern Africa.
Sterrhinae is a large subfamily of geometer moths with some 3,000 described species, with more than half belonging to the taxonomically difficult, very diverse genera, Idaea and Scopula. This subfamily was described by Edward Meyrick in 1892. They are the most diverse in the tropics with the number of species decreasing with increasing latitude and elevation.
Scopulini is a tribe of the geometer moth family (Geometridae), with about 900 species in seven genera. The tribe was described by Philogène Auguste Joseph Duponchel in 1845.
Digrammia atrofasciata is a species of geometrid moth in the family Geometridae. It was described by Alpheus Spring Packard in 1876 and is found in North America.
Eogeometer is a prehistoric genus of Ennomine geometer moths in the tribe Boarmiini. The type and only species is Eogeometer vadens, the specimen of which measured about 5 mm (0.20 in), and was estimated to be 44 million years old, dating back to Eocene epoch. Both the genus and species were described by Thilo C. Fischer, Artur Michalski and Axel Hausmann in 2019 as the first geometrid caterpillar in Baltic amber.
The Prussian Formation, previously known as the Amber Formation, is a geologic formation in Prussia, today mostly Kaliningrad Oblast that dates to the Eocene. It holds 90% of the world's amber supply and Baltic amber is found exclusively in the Prussian Formation.
