Your beautiful green fly is a Ornidia sp. (Syrphidae). It probably is Ornidia obesa, which is the most common and widespread species in this genus (of which four other similar-looking species are known).

Thanks Javier,

That's very nice how neatly the AICO aperture fits into the tube lens.
I'll be using a Mitutoyo M Plan Apo 10x (haven't received it yet...); it is narrower than the BD type (34 vs. 44mm), and I wonder if vignetting will be an issue?

Regards,

Eric

Javier, Your photos are fantastic! I'm especially impressed with the Mitutoyo 10x shots of this beetle (and the Tenebrio); like Rik says: a "wealth of detail...". If possible, could you please give more specific info on your tube lens setup with the Mitutoyo and morfanon (aperture type & position, d...

morfa view

I was very pleasantly surprised today, when I received my "Sierra" magazine March/April issue in the mail, to find John Hallmén's Camponotus ant head on the cover. Inside are six more large, beautiful insect photos from John -- including a two-page spread of his great leaf-rolling weevil image -- wh...

Charles -- your Eupholus weevil photo is truly magnificent! Stunning color and wonderful composition: reminds me of a pointy-nosed, floppy-eared dog riding in a car -- with its head in the breeze.

Hi Gustavo, This robber fly is a female of an Efferia sp. -- which is a very large genus (200+ spp.) in the Americas. As Harold says, the sword-shaped structure is the ovipositor (from tip of wing on); this shape of ovipositor is diagnostic for Efferia females. It looks like the abdomen has some 'ma...
