Your letter to the bugman:  Found on July 31, 2021. We live near a lot of woods, so often find many different species “hung over” near our porch light in the morning. We keep a list and have been able to identify most, but not this guy. Thank you!

Geometrid Moth: Eulithis species

Dear Sarah,
The abdomen on this Geometrid Moth is quite distinctive and we quickly located a matching image on BugGuide which is a member of the genus
Eulithis.  According to BugGuide:  “There is no reliable way to separate adults of these species without rearing or dissection.”

Geometrid Moth

Dear LJ,
This is a moth not a butterfly, and it is in the family Geometridae.  There are many similar looking species and we did a quick search on Butterfly House and could not quickly provide you with a species.  We hope a family identification is sufficient for your needs.

Probably False Crocus Geometer

Dear James,
This is a Measuring Worm Moth or Geometer in the family Geometridae, and that name comes from the movement pattern of the caterpillars, called Inchworms or Measuring Worms.  We believe your individual is a False Crocus Geometer based on images and the range map on the Moth Photographers Group.  As you can see, the spotting pattern on the wings is quite variable.  The species is also pictured on BugGuide.

But my beauty has no wings!

Flightless Female Moth

Dear Silvia,
We agree that this is a Moth, but we are not certain of the species or even the family, though we are leaning to Geometridae.  Females of certain species of Moths in the Inchworm family Geometridae and Tussock Moths in the family Erebidae are wingless, hence flightless.  Perhaps one of our readers will recognize your beauty and write in with an identifying comment.  

Flightless Female Moth

Dear Daniel,
Thank you so much for your reply. I got nuts trying to know even what the family was! I’m not entomologist, but biologist, hence very curious
Kind regards,

Kent’s Geometer

Dear DSC,
This is a Moth, not a butterfly, despite the uncharacteristic way for this Moth to fold its wings.  Often in very simplistic explanations differentiating Moths and Butterflies, it is generally stated that Butterflies rest with wings folded over their bodies while most Moths rest with wings held flat.  This is a Spanworm Moth or Geometer Moth in the family Geometridae, and we quickly identified it as Kent’s Geometer,
Selenia kentaria, thanks to this image posted to BugGuide.  According to BugGuide:  “adults mimic wilted leaves and hold wings over head at rest, while the larvae resemble twigs” and “adults fly March to August.”  According to Butterflies and Moths of North America:  “Caterpillar Hosts: Basswood, beeches, birches, maples, oaks, and other forest trees.
