I think this has to be Eristalinus taeniops... but can someone confirm this in case something else has eyes like this.

31.8.10 c8mm Lesbos, Greece.

Hi,
It's Eristalinus taeniops, I think. Smile
Sincerely yours
Sara

Thanks Sara. I think it has to be as nothing else I've seen has eyes like this, and the "band-eyed drone fly" E. taeniops is a Mediterranean species so the location is fine. I'm no expert, though, so usually seek confirmation for my IDs. Sometimes I'm spot on, sometimes wildly wrong, especially where hoverflies are concerned.., but they're very photogenic and sit around in bright sunshine so I take a lot of photos of them!

I’m not expert, too, about Syrphidae, but when I saw this image, interesting it for me. My teacher working on Syrphidae and I ask him, he said me that it’s E. taeniops and told me which he has this specimen in his collection. Your think about behavior activity of Syrphidae was interesting for me… Smile
Sincerely yours
Sara

Many thanks again Sara for getting some expert input from your teacher. I'll add this image to the gallery when I can find time, although there are some there already, but not from Greece. When i take photos I don't use flash, so i need very bright daylight. So I end up taking a lot of shots of insects such as syrphids that visit flowers in full daylight, or use sunshine to warm themselves up (that happens a lot in the UK on cool spring days) and am sure I'm missing lots of insects that prefer shade and the underside of leaves! One day I will get some flash gear for such things, and for insects of shady forests, but i actually prefer the great colours of insects and backgrounds you get with daylight. Some insects I photograph seem most active on sunny, very low wind, humid days, such as chloropids when they are courting, releasing pheromones and hovering slowly around in search of mates (at least Thaumatomyia notata does this from my observations).

this fly is rather common in Spain and Portugal.
Here comes a detailed photo I took to its head.

Thanks; great detail in the shot! I'm getting some extension tubes for my macro lens soon, so I shall be trying for this kind of shot soon as well!

Dear Nick Upton
Your think about behavior of Chloropidae was so interesting for me, cause I have such think, too, about it; but I wasn’t sure, now that you told it, I make sure which this think is correct…!Smile
I have a question, would you please lead me!
Is there any source about Chloropidae that I can more study about them?? Do you know??
Thank you very much. Smile

Sincerely yours
Sara

in Manual Palearctic Diptera there is a chapter dedicated to them...


quite a change from acrocerids to chloropids... odd? Smile

Hi Sara; I'm no expert on Chloropids, far from it, but am a trained behavioural zoologist so I notice distinctive behaviour and as I used to study pheromone communication in invertebrates, so was pretty sure I knew what I was seeing. A few months ago, around the time I posted some images of this behaviour : http://www.diptera.info/forum/viewthread.php?thread_id=29310 I did track down some online info on chloropids using eversible pheromone vesicles - check this: http://www.britannica.com/bps/additionalcontent/18/36877837/Male-flies-with-yellow-balls--New-observations-on-the-eversible-vesicles-on-the-postabdomen-of-male-Thaumatomyia-notata-Diptera-Chloropidae and think I came across some further academic references. I can't look those up again now as I have to leave home in a few minutes for a couple of days without email access, but will try to re-find them and will post them on the Chloropid wing-fanning thread for you if I find any (as we have gone off topic on this syrphid thread!).

the best photos with eversible glands WE have seen so far here in DI were these spectacular, really spectacular set of photos, though in LAUXANIIDAE... but worthy a view.. Grin


CAUTION: It can trigger some screams...

Great pics on that link. Now that's really showing off... Will try to get some closer pics of my chloropids next year once I get my extentsion tubes (they're v common in my garden) but they're awfully small flies...

Some flies preserved in ethanol and then pinned often get the eyes sunken, how can this be avoided? Best answer: I usually keep alcohol-collected material in alcohol

Yes, dipterologists from far abroad, please buy your copy at veldshop. Stamps will be expensive, but he, the book is unreasonably cheap Smile
