I'm with Carmen & Rik: nice image Harald! The subject is not a robber fly though, but a snipe fly (Rhagionidae) -- and likely a species of the genus Rhagio.

Cheers, Eric

As Rik has said, the beetle is a blister beetle, family Meloidae; specifically, it is Cysteodemus wislizeni.

Yes, a robber fly: Promachus rufipes. Interesting technique.

I did have a special advantage with this particular subject! My job for many years with the State of California was to identify fruit flies (Tephritidae) and other diptera, looking for dangerous agricultural pests. As I mentioned above, the ovipositor is an important character in helping to identify...

Canonian, sorry to cut your 'what is this' short -- but I was sure that one of the many other entomologists on this site would 'scoop' me!

Nice photo; is your fly from the Netherlands or nearby? If so, I think it may be this fruit fly Tephritis bardanae, which is common in Europe.

It's part of the ovipositor of a female fruit fly (Tephritidae). The fruit-stabbing part (the "aculeus" -- pointed at the tip, beyond the photo) is on the right; the broader part, center and left, is the "oviscape" -- an eversible tube, which can unroll (it is partly unrolled now) and extend the len...

Yes, definitely a soldierfly Laurie. Maybe a Microchrysa sp.

Antweb is actually a project that has been ongoing for some years (see < http://www.antweb.org/ >), though maybe the part about adding the BMNH ant collection is new (?). Rick is exactly right: the project is based on stacking procedures quite familiar to our group. The scope of Antweb is amazing, i...

Wow! A beautiful female Microstylum sp. (not sure which species 'though). Looks like it is very fresh ('teneral') -- hasn't reached full coloration yet. Wonderful photo (as always!).

Hi Papakatz45, If money is not an issue (Yow!), then why not purchase the two lenses being discussed and add two more: the EF-S 60mm Macro and the MP-E 65 Macro? The EF-60 is excellent and allows much closer focusing than the 100 (to about .7x -- ca. 90mm); and the MP-E is the 'King of the Real Macr...
