Best Geometer
The peppered moth *Biston betularia* is a common British moth notable for its camouflage and evolutionary adaptation. Originally light in color, populations darkened dramatically during the industrial revolution due to soot-covered trees favoring melanic (dark) moths. This demonstrated natural selec...
The large emerald (Geometra papilionaria) is a green geometer moth found across much of Europe, including Britain, and parts of Asia. Adults have broad green wings crossed by pale, wavy lines; the color fades after death or prolonged wear. The caterpillar feeds on deciduous trees, especially birch,...
The speckled yellow (Pseudopanthera macularia) is a species of moth belonging to the family Geometridae, native to Europe and parts of the Middle East. Unlike most moth species, it is primarily diurnal, meaning it flies during the daytime. The moth features distinctive bright yellow wings patterned...
The False crocus geometer moth is a North American insect notable for its vivid, uniformly yellow wings, which serve as camouflage against floral backgrounds.
The Dark-bordered beauty (Epione vespertaria) is a moth species in the family Geometridae that exhibits sexual dimorphism, with males and females displaying different coloration patterns. The moth's wings feature distinctive dark borders on primarily yellow or orange backgrounds. Dark-bordered beaut...
The argent and sable moth (*Rheumaptera hastata*) is a day-flying species of geometrid moth characterized by its contrasting black and white wing patterns. It is widely distributed across the northern hemisphere, with populations found throughout northern Europe, Asia, and North America. The larvae...
The green carpet, Colostygia pectinataria, is a geometrid moth found across much of the Palearctic region, including Europe. Fresh adults have patterned green wings crossed by darker and paler wavy bands, but the green pigment often fades in older museum specimens or worn individuals. Its caterpilla...
Maiden's blush is Cyclophora punctaria, a geometrid moth described by Linnaeus in 1758 and found mainly in European oak woods.
Yellow shell is Camptogramma bilineata, a common Eurasian geometrid moth described by Linnaeus in 1758 with yellow, cross-lined wings.
The Early Thorn is a widespread Palearctic geometrid moth distinguished by resting with its wings held tightly together like a butterfly, emerging in two generations annually.
The Canary-shouldered Thorn is a Palearctic moth recognized by its striking, bright yellow furry thorax, flying predominantly during the autumn months in wooded habitats.
The blood-vein moth (Timandra comae) is a Palearctic geometrid moth highly recognizable by the prominent reddish or pinkish post-median line that traverses its pale wings.
The Purple Thorn is a Eurasian geometrid moth notable for the distinct purplish-brown tint on its wings and its habit of resting with wings flat, resembling a dead leaf.
The mottled beauty, Alcis repandata, is a variable European geometrid described by Linnaeus in 1758, with larvae feeding on many trees and shrubs.
The Lunar Thorn is a Eurasian moth species recognized by the reddish-brown coloration and distinct crescent-shaped markings on its hindwings, flying in temperate woodlands.
The small blood-vein moth (Scopula imitaria) is a delicate European geometrid recognized by the distinct reddish-brown diagonal line crossing its pale yellow wings, flying in mid-summer.
Treble-bar is Aplocera plagiata, a Palearctic geometrid moth described by Linnaeus in 1758 and named for three dark forewing bands.
The willow beauty, Peribatodes rhomboidaria, is a common European geometer described in 1775; despite its name, its larvae rarely feed on willow.
The latticed heath moth (Chiasmia clathrata) is a widespread Eurasian geometrid insect, easily identified by the distinct dark latticed or net-like crosslines on its pale wings.
The common heath moth (Ematurga atomaria) is a daytime-flying geometrid widespread across Europe, noted for the extreme geographical color variation of its grey, brown, and white wings.
The September Thorn is a geometrid moth found in Europe and parts of Asia, distinguished by its bright yellow wings and its autumn flight period extending into early October.
The bordered white moth (Bupalus piniaria) is a common European geometrid that poses significant defoliation threats to pine forests, particularly in commercial timber plantations.
The August Thorn is a Palearctic geometrid moth notable for its deep yellow wings and early autumn emergence, with larvae feeding primarily on broad-leaved trees like oak.
The mottled beauty moth (Alcis repandata) is a prominent geometrid species found across Europe and Asia, distinguished by the exceptional variability of its bark-like wing camouflage.
The common white wave moth is a Geometridae species found across the Palearctic, first described by Carl Linnaeus in 1758, whose larvae feed on alder and birch.
The willow beauty moth (Peribatodes rhomboidaria) is a common Palearctic geometrid notable for its highly variable wing patterns and its ability to produce multiple generations annually.
Described by Ignaz Schiffermüller in 1775, the barred straw moth is a European Geometridae species recognized by its distinctive yellow and brown crossbands.
The engrailed moth (Ectropis crepuscularia) is a widespread Palearctic geometrid known for its intricately patterned wings and polyphagous larvae that feed on various deciduous trees.
The riband wave moth (Idaea aversata) is an abundant European geometrid distinguished by the contrasting dark cross-band on its variable wings, serving as excellent bark camouflage.
