Detailing the physical features, habits, territorial reach and other identifying qualities of the Mournful Thyris Moth.

 Updated: 6/15/2018; Authored By Staff Writer; Content ¬©www.InsectIdentification.org




Easy to see in the daytime, a mix of creamy white dashes, dots, and spots contrast with the deep black wings and body of the Mournful Thyris.



The Mournful Thyris looks somewhat similar to its relative, the Spotted Thryis. Larger spots and a lack of orange on the Mournful Thyris help differentiate the two. From a distance, wings looks worn out thanks to white spots along the edges. The abdomen is black with two white bands on the upper half, and a ring of white dots near the tip. Large white spots on the wings resemble white paint spatter. Adults are active from spring through most of summer. Caterpillars feed grapevines and clematis vines; adults drink flower nectar and are sometimes mistaken for butterflies.

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.
