Deep Yellow Euchlaena

Apart from their attraction to lights, Deep-Yellow Euchlaena are somewhat mysterious despite a range that covers half the continent.

Part of the Geometer moth family, the Deep-Yellow Euchlaena rests with its wings flat, allowing its rich yellow and brown shades to be fully displayed. The tips of both wings have light patches. Each hindwing has a tiny black dot in the center, between two thin brown lines that cross the wingspan left to right. Dark brown marks litter the entire wing surface, giving it the appearance of birch tree bark. The host plant that their caterpillars feed from is unknown. Up to two generations a year have been produced, but beyond that, little information has been collected on this species.

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.
