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 the antennae of the males are often feathered. They tend to blend in to the background, often with intricate, wavy patterns on their wings. In some species, females have reduced wings (e.g. winter moth and fall cankerworm).
Most are of moderate size, about 3 centimetres (1.2 in) in wingspan, but a range of sizes occur from 10–50 mm (0.39–2.0 in), and a few species (e.g., Dysphania) reach an even larger size. They have distinctive paired tympanal organs at the base of the abdomen (lacking in flightless females).

Famous quotes containing the word adults:
“Probably more than youngsters at any age, early adolescents expect the adults they care about to demonstrate the virtues they want demonstrated. They also tend to expect adults they admire to be absolutely perfect. When adults disappoint them, they can be critical and intolerant.”
—The Lions Clubs International and the Quest Nation. The Surprising Years, I, ch.4 (1985)
“The new concept of the child as equal and the new integration of children into adult life has helped bring about a gradual but certain erosion of these boundaries that once separated the world of children from the word of adults, boundaries that allowed adults to treat children differently than they treated other adults because they understood that children are different.”
—Marie Winn (20th century)
“What I wanted was to create thoughtful citizens—people who believed they could live interesting lives and be productive and socially useful. So I tried to create a community of children and adults where the adults shared and respected the children’s lives.”
—Deborah Meier (b. 1931)
