A damsel in distress called me to remove a ”big black moth”. I found her in a corner. Had her crawl on my hand and took some pics. After that she flew off and danced around me and landed on my back and crawled up to my ear as to say ”please take me outside”. I gently grabbed her and I did what she ask.
While doing so I was telling my co-workers about your site and was going to ID the moth. I went 10 pages deep and couldn’t find her.
Thanx in advance!

Leucanella species???

Leucanella species

Dear Mike,
We just spent considerable time trying to identify your Giant Silk Moth by browsing through the members of the genus
Automeris that are found in Mexico.  We had no success, and then we found members of another genus, Leucanella, and we believe we found your moth, however, we cannot be certain of the species.  This is a most unusual sighting, and to the best of our knowledge, Leucanella species do not stray as far north as San Diego.  See Leucanella lynx on Kirby Wolfe’s website, various Leucanella species on the Fauna of Paraguay website and various members in the genus on Saturniidae World.    We are contacting Bill Oehlke to try to get an identification.  We suspect he will likely want to document this sighting and we would request that you also provide him with access to your photos.  The big mystery for us is how did this moth get to San Diego??  Is it possible someone in your office who might raise moths is playing a joke?

Bill Oehlke Confirms and Questions
Hi Daniel,
It is a Leucanella species.
There are many san Diegos in the world.
Please check to see if you can find country. Even in some central and south
American coutries there is more than one san diego.
Bill

Ed. Note: We did write back to Bill to confirm the sighting was San Diego, California.

WOW Daniel!
No, no one here in the office would do anything like that.
Our office is located at 2241 Kettner Blvd. San Diego, CA. (32° 43.658′N- 117° 10.232′W). As you can see from the Google Earth kmz file of our location, we are right under the flight path of incoming planes to San Diego International  airport. There are no direct flights from South America to San Diego. Maybe it was a stowaway on a plane?
If you need anymore, please contact me.
Thank you,
Mike

Bill Oehlke provides additional input.
Hi Daniel,
I think this is a prank with regard to location or something someone
imported from at least as far south as central Mexico.
Sometimes there can be wind assisted strays, especially if there has been a
severe storm, but San Diego California is a bit far west of the path of most
tropical storms.
It is a Leucanella female, but without knowing its true source of original
location, I would only be guessing at species.

We can’t help but to wonder if we might be the first to report on a range expansion due to global warming, or perhaps she is only a stowaway on a plane.  Maybe one or more Leucanella caterpillars were smuggled in from Mexico.

We found this beautiful thing in July 2012. I tried to put it back and it kept going for the ground. So we decided to keep it in a can. It made a cocoon and nothing every happened. Tonight it arrived (10 months later). I would set it free tonight but it’s raining. I hope it will be okay overnight.

Cecropia Caterpillar

Hi Michelle,
Your identification of a Cecropia Moth Caterpillar and adult moth is correct.  Congratulations on successfully rearing this beautiful creature from the caterpillar through adult.  We wish there was better resolution in the photo of the adult moth.  It appears that the antennae are not especially plumose or feathery, indicating that this is a female Cecropia Moth.  If she is releasing pheromones, you might be greeted by her attracting all the males in the vicinity.

Daniel, thanks so much for your response. We set it free this morning, and I’ve attached a few pictures I took with my good camera so you. Can enjoy this beautiful creature.

We found a strange caterpillar in the desert of southern Utah on Hwy 95 south of the town of Hite on the Colorado river. We looked in the books and on line and could not find the little guy! He was about 3 inches long hiding in some Mormon Tea plant.

Buckmoth Caterpillar

Buck Moth Caterpillar

Hi Chris,
This spiny guy is a Buck Moth caterpillar in the genus Hemileuca.  Here is a similar looking individual from BugGuide that is identified as
Hemileuca griffini and Bugguide only has sightings from Utah.  According to the Butterflies and Moths of North America:  “Habitat: High desert scrub.  Range: Southern Utah south to central Arizona, west to southern Nevada.”  The site also notes:  “Populations should be inventoried and monitored to determine conservation status and impact of grazing on habitat.”  BugGuide also has these remarks:  “This species is considered to be threatened, due to its restricted range, and possible threats to its habitat from grazing of livestock. (4)  Like other species in this genus, H. griffini caterpillars have venomous spines that cause a painful sting.”

Hello,
We have these caterpillars in our garden on a number of bushes. The are numerous and devour every leaf before moving to the next plant. I live at Motshane in Swaziland and this is where the caterpillars are. I would like to know what moth or butterfly they come from.
Thank you for a wonderful site.

Saturniid Caterpillar

Saturniid Caterpillar

Hi Jacqui,
Alas, the best we can do right now is to provide a family for you.  This is a Giant Silkmoth Caterpillar in the family Saturniidae.  We will try to research the species later, but for now, we cannot take the time as we must leave for work.  We will also contact Bill Oehlke to see if he can provide the species for you.  The adult moths of members of the family Saturniidae are often quite large and beautiful.  It does look quite similar to this
Imbrasia species we posted recently from Rwanda.

Bill Oehlke provides an identification
Hi Daniel,
It is Gonimbrasia (Nudaurelia) wahlbergii
Please send more precise location and date if you can so I can document it
on the website.
Bill

Hi,
Where can I find information relating to the caterpillar. I am interested in the breeding cycle and would like to follow the caterpillar through the various stages.
Jacqui

Hi again Jacqui,
You already know what leaves the caterpillars feed upon.  You just need to provide them with a habitat for raising in captivity.  We do not raise caterpillars, but since you are now in contact with Bill Oehlke, he should be able to provide you with all the information you need.

Possibly Gonimbrasia zambesina Caterpillar

Possibly Gonimbrasia zambesina Caterpillar

Dear type written,
This is a Giant Silkworm in the family Saturniidae.  We believe it is in the genus
Gonimbrasia, and there are several species found in Malawi.  In our opinion, it looks close to the caterpillar of Gonimbrasia zambesina which can be viewed on the African Moths website.  The caterpillars feed on the leaves of Mango and some other trees.  We will check with Bill Oehlke to see if he is able to determine the species of this caterpillar.

Bill Oehlke confirms identification
Daniel,
I am pretty sure you are correct.

Here’s a photo of a ”Mopane Worm” I mentioned in a comment I just posted about a similar caterpillar from Tanzania. This is Gonimbrasia belina (Saturniidae), on Mopane, its namesake foodplant (Colophospermum mopane; Fabaceae), at the Hobatere Lodge, ca. 80 km N of Kamanjab, Damaraland, Namibia, on 26 March 2010.

The larvae are collected, dried, and highly prized as food (tried one, but too “spiky” for me to really enjoy).

Hi Julian,
Thanks so much for submitting this beautiful photograph of such a stunning caterpillar.  We see the resemblance to the Tanzanian Caterpillar we just posted.  The adult moth is pictured on the African Moths website.

I encountered one of these during my recent trip to Uruguay and was told by the locals to stay away since it’s poisonous. The bright green/yellow color would definitely imply that it doesn’t want me to get too close. Any idea what it is?

Automeris Caterpillar

Leucanella viridescens viridior Caterpillar

Dear Alex,
We are nearly certain your caterpillar is a Giant Silkworm Caterpillar in the genus
Automeris, which includes many species of stinging caterpillars including the Caterpillar of the North American Io MothWe will check with Bill Oehlke to see if he can provide a species identification.  We often hear that locals have superstitions about perfectly harmless species being dangerous, including the Black Witch and the Lanternfly or Machaca, but in this case, the locals are right.

Bill Oehlke provides a correction:  Leucanella viridescens viridior
Hi Daniel,
It is Leucanella viridescens viridior, and they can give a nasty sting.
Bill Oehlke

Hi Daniel,
Thanks very much! Glad I didn’t touch it. :)

Ed. Note:  Bill Oehlke notes that it is the “Same subfamily Hemileucinae” as Automeris, hence our initial confusion.
