Fuzzy White Stinging Caterpillar with Black Spikes - Acronicta rubricoma

Fuzzy White Stinging Caterpillar with Black Spikes - Acronicta rubricoma
Hempstead, Waller County, Texas, USA
April 16, 2012
We have these fuzzy white caterpillars everywhere. 23 on one tire of my Jeep alone. They are fuzzy and whitish/yellowish with black hair spikes going down the center of the back. The tip of each of the black spikes is white. The head is black. These caterpillars just suddenly appeared a few days ago. They seem to swarm in various spots around the yard.... On one tire of my Jeep and all over the bird bath today. They do sting so we are having to be very careful as we go about... I don't know if this matters but the day before we started noticing these we had dozens of Mourning Cloak Caterpillars climb our house and form chrysalises in the eaves. I would love to know what they are... I will take a better picture tomorrow....

We have those exact caterpill
We have those exact caterpillars at our house also. They are everywhere. We live in South Texas(Mathis) Did you ever find out exactly what they are? Where do they come from? Are they poisonous?

Can you raise some of yours
and take pictures of the caterpillars and the adults?

Surprised that they sting
Had never heard that about this genus. Would it be possible to gather a couple and raise them? It would be great to see the adults of these caterpillars.
Looking forward to a few more images of the cats.

Raising them...
Could anyone give me some tips on how to do that?

for these
i'd just get a dollar store plastic box, wash it out rinse it good dry it, put a paper towel in the bottom, toss a few leavesfrom your tree in there,and sit it in the garage or other unheated or cooled room. if they eat the leaves give them more..if they go under the towel thats good they will pupate down there. you can dump the frass each day and replace the towel if they are feeding, and when they go under just take the lid off and let it all dry out after about 3 days.then replace the lid but leave them something to climb onto, when they eclose. it will be fun. you can also do a couple of your tiger moths the same way! (then you'll be hooked like us!)and doing stuff like this! click to see yankee doodle grow up

There's a nice article

was i correct that this is a dagger? i too was surprised they sting. however, the hickory tussock has an irritant..

I should have specified. My husband had it "sting" his neck. It didn't hurt his hand when he brushed it off but we believe the black "spikes" have some type of irritant as he had 5 bright red pin pricks on his neck and it burned/itched for around 2 hours. BUT it also could have just been an allergic reaction to it.

Yes, it looks just like
the one you linked to. We've always wondered if there is only one species that looks like this???

i wish i could get some that look like this.
i love rearing its what i am best at. im still waiting for that white caterpillar from last year

hopefully she will raise them and get them in the record..
it is allways exciting to see new stuff. im stuck here with new hatchings and no

looks like
this of course i am often wrong..
