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,
Silvia

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.

Your letter to the bugman:  I saw this moth on my front porch today,  August 30. I think it look like its camouflage is to appear as fungus on a tree trunk. Can you help me with the name of the species? I looked in my North American Wildlife guide, but couldn’t find a match.

Geometer Moth, possibly Euchlaena muzaria

Dear Elena,
While we don’t have time this morning to research the species of your interesting moth, we can tell you it is a member of the Geometer Moth family Geometridae.  We will attempt a species identification later in the day.

Update:  Based on this BugGuide image, we believe this moth is Euchlaena muzaria.  It is also pictured on Discover Life and Moth Photographers Group.

Your letter to the bugman:  Hi,
I recently have had a lot of moths in my house, all of which different sizes and colours. This one however caught my eye after entering our house late at night after we left our bathroom light on!
I’m wondering if you have ever seen one with this distinct ‘leopard print’?

Magpie Moth

This is a very easy ID for us because we recently misidentified a freshly eclosed Magpie Moth, mistaking it for a Tiger Moth.  According to UK Moths:  “A very distinctive species, this was a favourite with early collectors, who used to breed it to obtain unusual coloured and patterned forms.  Quite common in most of Britain, though less so in Scotland. … The moths fly in July and August and are regularly attracted to light.”

Thank you so much for your time and reply Daniel, that’s absolutely brilliant!!

The Magpie newly eclosed

Dear Elaine,
The nonspecific response is that this is a Tiger Moth in the subfamily Arctiinae, and it is freshly eclosed which means it has recently emerged from its pupal stage and its wings have not yet fully expanded and hardened, which is making our ability to identify it more difficult.  It most closely resembles a Garden Tiger Moth,
Arctia caja, as pictured on UK Moths where it states:  “Another species which was a favourite with early collectors, who selectively bred it to create unusual colours and forms.  Once a quite common moth in most of Britain, it seems to have declined in many places in the last few years.  It flies in July and August, and will regularly visit the light-trap.”  We would even entertain the possibility that a modern breeder might be releasing some “unusual colours and forms” back into the wild in an effort to help remedy that they “have declined in many places in the last few years” but the markings on the thoracic region as well as the scalloped wing edge eliminate the Garden Tiger Moth as the proper identification.  The only other Tiger Moth profiled on UK Moths that it resembles is the Cream-Spot Tiger Moth, Arctia villica, but in that species, the spots are white on a dark ground while your moth has dark spots on a white ground.  We are going to contact Arctiid expert Julian Donahue to get his opinion.

Dear Daniel
Thank you for looking into the moth that I saw it will be interesting to hear what your expert has to say. The moth wasn’t really moving and I got very close to it and moved it on it’s stick to photograph, I expected it to fly away but it stayed in the same place.
Thanks.
Elaine
Correction Courtesy of Julian Donahue:
Easy to be fooled by a colourful (since it’s British) un-expanded moth, isn’t it?

This is The Magpie, Abraxas grossulariata (Geometridae).

All the best,

We had a bout of deja vú because according to UK Moths:  “A very distinctive species, this was a favourite with early collectors, who used to breed it to obtain unusual coloured and patterned forms.  Quite common in most of Britain, though less so in Scotland. … The moths fly in July and August and are regularly attracted to light.”
