Straight-lined Plagodis Moth (Plagodis phlogosaria)


Detailing the physical features, habits, territorial reach and other identifying qualities of the Straight-lined Plagodis Moth.




The coloring on this month depends on the season it was born in.

Straight-lined Plagodis moths have a wide center band of color thanks to two lines of dark color that stretch across the wings. One line is curved near the head, but the other is straight and closer to the bottom of the wing. The bottoms of the wings are sculpted with a few gentle curves. Moths that form in the spring are colored differently from moths that form just months later in the summer. The early brood tends to look darker. The area near the head has red or pink tones to the brown hair. The middle band has brown coloring that may be light or dark in tone. The lower part of the wings have purple and black smudges on the inner parts of the wings, almost like they were slightly scorched. The summer form is more yellow and much lighter in color. The head area is yellow, the middle is a paler yellow, and the bottom smudges are still black, but with little if any purple undertones. Even the body is yellow.

The gray-brown caterpillar for this moth feeds on the leaves of all sorts of deciduous trees. It has bumps on it which make it easy to mistake for a small twig. Alder, birch, basswood, black cherry, and chokecherry are common food plants. Look for adults in or near woodlands. Two broods are 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.

Butterfly and Moth Anatomy
Graphic showing basic anatomy of a common North American butterfly and moth insect
1
Antennae: Butterflies and Moths have a pair of antennae on the head used as sensors.
2
Head: The head is home to the insect's eyes, antennae, and proboscis.
3
Thorax: Home to the three pairs of legs as well as vital internal organs.
4
Abdomen: Contains vital internal organs such as the heart(s) and reproduction facilities.
5
Forewing: The upper, forward wing pair used for flying.
6
Hindwing: The lower, rearward wing pair used for flying.
NOTE: Butterflies and Moths are part of the Lepidopteran order as they share many similarities.
