Predaceous Larva - Anatis rathvoni

Predaceous Larva - Anatis rathvoni
SFSU Field Station, Sierra County, California, USA
July 8, 2008
Size: ~ 1 cm
Found on the side of my tent in the morning. A coccinellid larva preying on a lepidopteran or sawfly larva?

Moved from Giant Lady Beetles.

Breakfast is a sawfly
Too many prolegs for a caterpillar. I agree with Tim, the lady beetle is definitely Anatis and by location it must be A. rathvoni.


Anatis sp.
using my new professional reference key to larvae (1), I'm able to confirm what was already commented below: "looks like this one which is Anatis" :)

Thanks, Tim!
Great that you're able to ID some of these now...

A. rathvoni?
Your location would suggest this must be A. rathvoni. Have you seen any other adult Anatis sp. around your area?

Brief trip -
this was found on the side of my tent during a Sierra insect bio. class - didn't see any adult coccinellids around, that I can remember... Hope to get back there next summer!

Moved from Ladybird Beetles.

Looks like it might be unique to the west coast - hopefully we'll get an ID soon.

Thanks, Tim!
Probably would not be useful for the West coast, but do you have any idea whether this old book would be useful for ladybird larva ID? I thought about picking it up, but hoped you might know something about it:

The Larvae of the Coccinellidae.
GAGE, J. HOWARD. 1920.

it might be good, but I don't know anything about it and it's not included in the references for the family in American Beetles. They cited a larvae key by Rees and Gordon from a 1990s periodical, which I'm attempting to have copied and sent to me. Not too much has changed with NAmer Ladybirds since 1920 (except for lots more color printing) so it might be a fine reference. If you get it, please let me know how it looks.

I agree - ladybird larva
It looks a lot like this one:

Can't help with what it's eating.
