False Crocus Geometers are medium-sized yellow moths that could almost pass for butterflies.
The False Crocus Geometer is a yellow moth with such variation, it is difficult to tell it apart from a close relative, the Crocus Geometer Moth. It could have purple-brown lines crossing its wings, or disconnected lines instead. Some individuals are pale yellow, but many are generally a richer, deep yellow. Small spots and freckles of brown or purple may be present all over the wings. Because so many variations resemble the variation of the Crocus Geometer Moth, the two are identical and might even be a single species. For this reason, the images seen for the False Crocus Geometer also appear for the Crocus Geometer.
A small purple, yellow, or white flower blooms from the low-growing crocus plant. It is considered a cold-weather perennial and is often the first blooming flower in spring, even if snow is still on the ground. Despite its name, the False Crocus Geometer's caterpillar feeds on a diverse group of trees and shrubs like dogwood and goldenrod where the woody branches hide the twig-like larva. Catnip and ivy are also good forage. One or two broods can be produced each year.

Note: 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 as they are driven by environmental factors (such as climate change), available food supplies and mating patterns. Grayed-out selections indicate that the subject in question has not been reported in that particular territory. U.S. states and Canadian provinces / territories are clickable to their respective bug listings.
Butterfly and Moth Anatomy
Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.
Head: The head is home to the insect's eyes, antennae, and proboscis.
Thorax: Home to the three pairs of legs as well as vital internal organs.
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
Forewing: The upper, forward wing pair used for flying.
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
