Lady beetle - Anatis rathvoni

Lady beetle - Anatis rathvoni
Donner Pass, California, USA
July 1, 2006
This looks like H. axyridis, but the front and sides of the elytra are odd shaped.
I found a picture of Anatis rathvoni in (1) that looks pretty close.

Moved from Anatis.

Moved from Ladybird Beetles.

2nd vote for Ana*tis
note the head pattern, different from Adali*a. Identical, and pronotum pattern similar, in Ana*tis mali. Variant of it?

Not an ID
But this image of a Two spotted ladybeetle (Adalia bipunctata) is somewhat similar.

It looks close
but I'm leaning towards one of the Anatis sp. because the odd protrusions on the front of the elytra and the dark spots have a pale ring around them.

I concur with Anatis, and probably A. rathvoni. This individual is pretty 'young,' as they get progressively darker with age....Donner Pass, eh? Was it eating a conspecific? :-)

keys to A. rathvoni
using Gordon's ref., this one keys to A. rathvoni. The "hips" on the lateral elytra margins and stronger angles on the shoulders are unique to A. rathvoni and A. lecontei, but A. lecontei has black pronotum lateral margins (and no spots). That said, a slight caution that this local is a bit further east than Gordon's distro shows. But if local were the only criteria, of the genus, only A. lecontei is shown from the Rockies in CO.

A. rathvoni
Tim, thanks again for another species identification. Donner Pass is in the northern Sierras in central/east California. It shows up in a field guide for the Sierra Nevadas (1), so range would seem to be ok.

oops . .
looks like I'm helping to confirm those statistics of what little people know about our own geography/history. How embarrassing! Well, at least the beetle actually does fits within the expected range. Thanks for the correction :)
