If eyes really are a window to the soul, that fly has the soul of an artist. Such beautiful colour palette and pattern. Great job capturing it too, the lighting works really well to bring out the eyes.

Excellent! Judging from the build of the antennae you might be right about soldier fly.

Cheers

It's an excellent picture!

I'm not sure what is meant by "soldier fly".

BugGuide and many other sources put the name "soldier fly" with family Stratiomyidae, which doesn't look right.

For this one, I'm thinking family Tabanidae, commonly called "Horse and Deer Flies". The antennae and mouthparts look reasonable, plus this family often has eyes that are strikingly patterned like this.

Rik, your reply teaches me not to reply to ID threads immediately after getting up in the morning, at least not before having drained a big mug of coffee :D.

You are right, of course - that's a tabanid and not a stratiomyid. The iridescence pattern of the eyes should have been tell-tale sign enough for me, let alone the anntenae :oops: .

However, to be absolutely sure, Antonio, you should post an overview image of the entire insect.

Cheers
Harry

nto, many thanks for the ID and especially the very precise link into BugGuide. The face of this species looks a lot different from other stratiomyids!

How big is this thing, anyway?

is true, I was insecure, however found very useful BugGuide

length bug is 1.5cm

board left eye to the right-hand edge is 4mm

antennae is 5mm

I wanted to do vertical frame with antennae, then I decided for easy positioning light horizontal :wink:

Thanks for the size information.

Another question...

With stacked lenses, most people stop down one lens or the other but not both. I notice you are stopping down both lenses, and I'm curious why.

Did you test various ways and find that stopping down both lenses works better?

Well, thanks, but that doesn't have an influence on what I wrote above.
Sometimes I'm a bit too rash with my ID's - 25 years as a professional taxonomist should have told me better :) . My only excuse is that I normally work with rove beetles.

Rik sò not as I understand it, and question is diaphragms lenses:

105 a f/6.3 and 50 a f/4 produces good quality (50mm a f/4 sticker board a bit), with good fall dof, I very interested in blur, currently my best setup that I have, later add good lens for microscope :)
