[technical: Eric, the ending of albius looks weird -- is it correct spelling?]

Moved from Eudioctria.

Thanks v. Yes, the name does look a bit weird but it is correct (is Walker's original spelling). Dioctria is actually a male name (= hunter); not sure what 'albius' means, probably refers to a proper name, as was originally capitalized.
Eric

 
Thanks, Eric --
that Albius is a proper name did cross my mind; but if Dioctria is masculine, then media &c feminine adjectives look inconsistent...
i spent an hour last night harmonizing specif. epithets in a moderate-sized beetle genus -- mostly checking sources to find out which gender it should be

 
Yes -- just after I posted my
Yes -- just after I posted my reply I realized the problem with "media"! I agree that eventually some changes need to be made -- assuming that Dioctria is positively masculine (I'm mostly clueless re. classical languages). "Diokter" is hunter or pursuer in Greek and is normally masculine (always??). Whatever the gender, the specific names in Dioctria (etc.) should be in agreement (though this is not really an issue for BugGuide...).

 
diokter is no doubt masculine...
...but Dioctria must be feminine -- like Alexander vs Alexandria or 'mister' vs 'mistress'... or 'dister' vs 'distress' :))
so media is correct, and we probably should leave everything as is

 
I was just thinking...If it really is
I was just thinking...If it really is 7m long, that would make it the second biggest robber fly I have ever seen!

 
Thanks - Fixed
But then, YOU didn't see it - I did :)

Eudioctria media, female.
I would have liked to see a bit more detail of the thorax and head but I will go ahead and confirm it as E. media. This is the common small Eudioctria in your are(a it looks like this and the size fits). New BugGuide record - congrats!

 
Thanks...
Thanks for your time :)

Will keep looking...

No E. media in Taxonomy so I just moved it to Eudioctria.

It does look like a Eudioctri
It does look like a Eudioctria sp. (E. media would be my guess); need higher resolution photo for ID. (If possible, please submit a 500-750 KB version of the image on the left.)

 
That is highest...
Those are the highest res I have. I do have a few others like "the one on the left" if you want them but no higher res.

Is there a particular area you want to see? I may have other images of that area.

Been watching all day for his/her return.

at least half a dozen Eudioctria spp. occur in California

 
Thanks for Info!
BugGuide doesn't show any:
http://bugguide.net/node/view/23377/data
so that's a surprise to me.

Hope someone can id this one :)

 
our robber team is good!
re: "BugGuide doesn't show..."
BG is definitely not a source i would rely upon for range anyway; as you can see above the map, "Range and date information may be incomplete, overinclusive, or just plain wrong" -- some of which is usually the case. Conservatively, BG maps reflect an avg. of 10% of known state records for 90% of taxa.

for the future: only names of genera and [sub]species should be italicized, never higher taxa

Robber Fly
Looks like a Robber Fly in the Asilidae family.
