Bright yellow with lines of pink, the low-flying Chickweed Geometer is a cheerful summer moth that shows its colors all day long.

Chickweed Geometers are small moths with an uncommon color combination. Yellow wings have a pink dot on each forewing and two pink bands that cross the wings near the bottom edge: one thick, one thin. They also have a pink fringe along the edges of both forewings and hindwings. Some individuals' markings are a softer, rosy pink while others are a deeper fuchsia. The antennae of males are almost feathery in appearance. Female antennae are more ordinary. They look alike in every other way.

Caterpillars of Chickweed Geometers feed on short growing plants like chickweed (their namesake), stitchwort, knotweed, and clover. Almost all of these plants are considered weeds. The Chickweed Geometer can be found fluttering about, low to the ground, in yards, parks, fields, meadows and gardens. Look for adults from late spring to mid-autumn. August is a month of high activity. They are daytime fliers which makes for abundant opportunities to spot them.

A Note About Territorial Reach: Keep in mind that an insect's reach is not limited by lines drawn on a map and therefore species may appear in areas, regions and/or states beyond those listed above. Insects are driven by environmental factors, food supplies and mating patterns and do not nescessarily work within hard-and-fast territorial lines like we humans do.
