unknown Caterpillar - Acronicta spinea

unknown Caterpillar - Acronicta spinea
Point Reyes, Marine County, California, USA
June 25, 2009
Size: 3 cm
Found two of these caterpillars feeding on brush lupines. I thought I was collecting Platyprepia virginalis but when I got back and looked at the guide they did not match. They look like a Hemileuca with the spines but I could not find one that fits.

Moved from Tiger Moths.

Acronicta spinea
This is a pretty signifcant find. It matches an inflated larva specimen of Acronicta spinea, the most recent records of which are from the 1960s. It's a California coastal dune endemic.

Dr. Schmidt, might you have any time
to leave some comments on some of these?



help in moving picture
This should not be placed under Platyprepia virginalis. I did not place it here, if so by mistake, and I do not know how to move it out from under this sp.

I don't believe...
...that your picture has been moved anywhere at this point. Could you give me more details as to why you think that it has been placed under P. virginalis?

Moving pictures
Hello Harsi:

When I typed in P. virginalis to see pictures of that species, one of the pictures is of the caterpillar I was asking help to ID. I had not intended it to be placed in with that sp. Maybe it ok, and when I do get an ID it will be moved to the right place.


Hi Richard,

I understand now why you were confused. Please click on the link below and read this brief discussion for an explanation of how the search feature works on this site:

If you view your image, you will see that the heading at the top of the page still says "ID Request". If your image had actually been moved to the species page within the guide itself, the heading at the top of the page would look like it does here:

I hope that helps make things clearer for you!

Thanks Haris, I understant n
Thanks Haris, I understand now.
