Moved from Spiny Tachina Fly.

 
Timely move, Aaron -
Thanks! In my file I've listed this fly for some time as P. rutiliodes nigrescens.
This fly, that is the larva, is considered an internal parasite of Edwards' Glassy-wing, Hodges #8222. See:
Hsu, Y. F. and J.A.Powell. 1992. "Hemihyalea edwardsii (Packard) (Lepidoptera:Arctiidae) is the Host of Paradejeania rutilioides (Jaennicke) (Diptera:Tachinidae) in Central Coastal California." Pan-Pacific Entomologist 68(1): 64-65.
I think I put this reference on the species page some time ago.

 
We're on top of it :-)
Saw your reference on the species info page...thanks for posting that. I added a link to BG images of Hemihyalea edwardsii there. It's currently listed as Pseudohemihyalea edwardsii on BugGuide...guess someone recently found that was a prior name? Since Paradeanjeania r. n. seems so fond of Coyote Brush, I thought the moth might also be associated with it. But apparently it uses oaks as its host.

BTW, on a different (dipteran) topic...I posted some images of Thevenetimyia californica recently (I think they're that taxon, but I don't have a key). Check 'em out if you get a chance:

 
I agree, you've already placed them correctly -
They're both females, and the median longitudinal stripe of black tomentum as well as the wing pattern, are diagnostic.

 
Thanks Hartmut
Good to get your feedback. I'll edit to check the "female" boxes for the posts.

I think
I saw that S. Marshall had termed this the Hedgehog Fly. Don't know if he coined that or not.

 
Interesting -
When I first saw this fly it reminded me of a hedgehog, though they're 'old world'.
Your comment suddenly recalls a pet hedgehog we called Bogumil (after a character in Gregor von Rezzori's Maghrebinische Geschichten / Tales of Maghrebinia.). We let it go after a while.
Back to this fly, they have been reported to use Hemihyalea edwardsii as larval host. I hope to see those moths.

Size
I'm just curious ; what is the size of this fly ?

 
Sorry,
I just added the size (see above), about that of some bumble bees.

 
Thanks
Ok, thanks! It's a beautyful beast. Unfortunatly, with don't have such fly in Québec.
