Editing Geometer moth (section)

==Adults==
Many geometrids have slender [[abdomen#Other animals|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 the [[antenna (biology)|antennae]] of the males are often feathered. They tend to blend into the background, often with intricate, wavy patterns on their wings. In some species, females have reduced wings (e.g. [[winter moth]] and [[fall cankerworm]]).<ref name="bugguide.net"/> Most are of moderate size, about {{convert|3|cm|abbr=on}} in wingspan, but a range of sizes occur, from {{convert|10|-|50|mm|abbr=on}}, and a few (e.g., ''[[Dysphania (moth)|Dysphania]]'' species) reach an even larger size. They have distinctive paired [[tympanal organ]]s at the base of the abdomen (these are absent in flightless females).{{cn|date=November 2019}}
