Dear Bugman, what are these little guys?They were on a wall inside my house this morning. At first I thought they were ants buy they are about half the size. They appear to be some kind of worm – with legs? Until I took the picture I couldn’t see the legs at all. They weren’t really moving, except to rear up at me when I got close.

Probably Woolly Bear Hatchlings

Probably Woolly Bear Hatchlings

Dear Squirmy Wormies,
These are newly hatched Caterpillars, probably from the subfamily Arctiinae, the Tiger Moths.  The caterpillars of Tiger Moths are frequently called Woolly Bears because of their furry appearance.

I was searching in my yard for any type of bug I could possibly find, so I picked up and old pipe, tipped it over and out rolled a black and orange fuzz ball! I was very exited by this, because I love caterpillars, which I am pretty sure this is. I think it is a pretty common type. Pretty please with cherry’s on top help me identify it!

Dear Gracie,
This Woolly Bear is the caterpillar of the Isabella Tiger Moth.  According to BugGuide:  “The second brood overwinters as a caterpillar and pupates in Spring.”
  That means your caterpillar should make a cocoon very soon.

Dear Daniel,
Thank you very much for writing me back! I am looking very forward to seeing the cocoon. At first when I found the caterpillar I was very worried it was dead, because it wasn’t moving. It took a little while for it to do anything, but when it did I was very exited! Thanks again!

I would like your help in identifying this species of caterpillar. Has you can see in the photos, is body is bright orange with some sort of clack spikes and little black hair all over the body.
They appeared on a creeper-weed like plant, and seems to be quite the number on them in a small area.
Its summer in here, with days with high temperature and high humidity and rains, so it’s possible the plant and/or the bugs are travelers of these stormy weather.
Thanks a lot for any input in the mater.

Caterpillar

Dear Eduardo,
We have not had any luck finding any matching images online from Argentina, but your caterpillar reminds us of the Polka Dot Wasp Moth Caterpillar or Oleander Caterpillar, Syntomeida epilais, a species found in the Caribbean and in Florida.  We believe your individuals are either members of the same genus, the same subtribe Euchromiina or a member of the Tiger Moth tribe Arctiini, depending upon how closely they are related.  Perhaps one of our readers will be able to assist in this identification.  Knowing the name of the “creeper-weed” upon which they were feeding might help.

Update:  March 16, 2016
Today we got a comment from Eduardo that included these two images.  Our general identification remains unchanged, and this is most definitely a Wasp Moth in the subtribe Euchromiina.  We will check with Julian Donahue to see if he can provide an identification.

Woolly Bear

Woolly Bear

Dear Zack,
This is a Woolly Bear, the caterpillar of a Tiger Moth in the subfamily Arctiinae, but we are having a problem with its species identity.  We scoured BugGuide and we found an image of
Hypocrisias minima posted to BugGuide that is the closest match, but we are not satisfied that is a correct ID.  The Caterpillar of the Virginia Ctenucha pictured on BugGuide also looks similar, and it is reported from Colorado, but again, it does not look like an ideal match.  This Tiger Moth Caterpillar from Colorado posted to the Life of Your Time blog is also somewhat similar.  We are going to contact Julian Donahue, a Lepidopterist specializing in Arctiids in the hope he can provide some information.

Julian Donahue Responds
 The caterpillar may just be a color form of Pyrrharctia isabella, the “standard” woolly bear.
I suggest you contact the caterpillar guy, David Wagner at Univ. of Conn., who is publishing books on the subject.

David Wagner Responds
I am not sure I have seen it before and am very, very intrigued.
I am writing a book on caterpillars of western North America and I don’t think I have seen this one before.  It is possible it is the very rare Alexicles aspersa.  If not something in the genus Hypercompe.
Was the individual saved?  I would be quite interested in learning more about the elevation and location, and especially altitude of the capture.
Thanks for sharing.

Thanks for the information Dave.
I run the pop culture website What’s That Bug? and the photo was sent to my site.
I will write back and request additional information and get back to you.

Unfortunately I did not save it because I did not want it to starve. I am around 7500 in Crystal park Manitou Springs Colorado In a mountain community. The mountain Is covered in pine, fer and blue spruce with large spots of Scrub Oak. It get up to the 90 degree weather in the summer time and get down to the 4 degrees and lower in the winter. Thank you if you need more in formation please let me know and can I have David Wagner email in case he whats to talk to me.

Can someone please identify these caterpillars. They are infesting one of my plants :(

Spotted Oleander Caterpillar

Spotted Oleander Caterpillar

Dear Playacofi,
Knowing the plant host is often a great help in identifying caterpillars and other herbivorous insects.  This is a Spotted Oleander Caterpillar,
Empyreuma affinis, and it is commonly found feeding on oleander.  According to Featured Creatures:  “It is a native of the Caribbean region and has been recorded from Guadeloupe, Martinique, Haiti, Dominican Republic, and Cuba.”  The plant in your image does not appear to be oleander, which is the food plant identified on BugGuide.  You can compare your image to this image on BugGuide for verification.

Woolly Bear we believe

Dear Valeria,
We have not had any luck identifying your Caterpillar, but we suspect it is a Woolly Bear, the caterpillar of a Tiger Moth in the subfamily Arctiinae.  Perhaps one of our readers will have better luck identifying this orchid eating caterpillar.  You can also try writing to Cesar Crash who runs Insetologia, our sister site from Brazil.  Should Cesar provide you with a species name, please write back to us so we can update your posting.
