Hydriomena Moth (Hydriomena spp.)


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

 Updated: 6/25/2019; Authored By Staff Writer; Content ¬©www.InsectIdentification.org




The members of the genus Hydriomena are hard to tell apart, but hints of green and gray are common in many of them.



The woodsy moths of Hydriomena are very good at blending into the trees that they sit on. Wings are typically held open flat, giving such a low profile that the presence of the moth is difficult to detect. The mottled patterns of gray, brown, and green on the wings of many species perfectly mimic the lichen-covered tree bark found in every forest. Most have a swath of light coloring across the middle or lower part of the forewings. Moths in this group are also called Highfliers.

Look for moths in the genus Hydriomena along the edges of evergreen woods and forests. Some species are tree specific when it comes to choosing a host plant for their offspring; others are more varied and may choose deciduous trees. Aspen, alder, fir, spruce, pine, and tamarack are used by members of this genus. Hiking around areas with lots of trees in the spring and summer is a good way to try and spot them if one is up for the challenge.

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
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.
