Despite its name, the Crocus Geometer uses many types of trees and shrubs as host plants for its young.
The Crocus Geometer is a yellow moth that has variable markings on its wings. Purple-brown lines cross the wings of some; broken lines can be seen on others. Some individuals are very pale while others are a buttery yellow. Faint spots, specks, and marks may litter the wings or be sparse. The False Crocus Geometer is identical though it is said to be typically a darker yellow. In reality, the two are indistinguishable and may even be a single species. For this reason, the images seen for the Crocus Geometer also appear for the False Crocus Geometer.
A crocus is a small flowering plant that usually blooms in colder seasons. It is often the first flower to emerge, even through snow, in spring. Despite its name, the Crocus Geometer's caterpillar feeds on a diverse group of trees and shrubs. Cherry, elm, maple, and basswood trees as well as rose, viburnum, blueberry, and currant shrubs provide leafy nutrition and great camouflage for its twig-like body. 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.
