There was an accident in a tunnel just after we crossed from the Bulgarian border that created a huge backup on the road. While we were at a complete stop on a very warm day in late August we picked up some uninvited passengers we couldn’t seem to shake. 4 Humans and 3 Flies in a BMW wagon. So, to amuse myself I took pictures of them. One in particular was much more interesting than I was expecting.
If you are able to help with identification that would be lovely. :)
Next up, flies in Germany. :)

Flesh Fly with hitchhiking Mites

Dear Curious Girl,
How sad that your human passengers were less interesting than this fly.  We believe this is a Flesh Fly in the family Sarcophagidae.  You can see additional images and read about North American species on BugGuide.  Interestingly, it appears that this Flesh Fly has picked up some hitchhikers of its own.  The red dots on the thorax and leg are most likely phoretic mites that are hoping to be transported to their next meal.

Oh, that makes sense except this fly was no bigger than the others and they were all what I would call, “standard” fly size not one of those big ones like the North American versions seem to be from descriptions but my understanding is these are worldwide and there are many different varieties and sizes?
However, up till now I had thought the red was just pretty decorations adding interest to the fly.
As for the Sarchophagidae it would seem the other two flies I sent with the Flesh Fly could then be Satellite (metopia) Flies which puts them in the same family (? is that correct? Family? I get so confused by classificiations).
Pretty cool they have live births instead of laying eggs.
Anyway, the day I sent these last pics to you I went out here in Cyprus to an explosion of bug life so captured pictures of dozens of interesting flies and little (+ bigger) bees among other things. So, expect more from me soon. :)
And thanks so much for the assist. It’s soooo cool to know these have names and descriptions in the world. :)

I have never seen such a bug with a snorkel. This bug was in a tub of clothing that was outside and filled up with water. The long tail or whatever it is is what made me inquire. I hope you can identify this bug?

Rattailed Maggot

Hi Larry,
You encountered a Rattailed Maggot, the larva of a Drone Fly,
Eristalis tenax.

Hi there, I found this very minute bug roaming around the rotting stump of a fallen tree. This one is quite lighter in color than the other bugs similar to it. It has those pair of big red eyes. I’m not sure what this is really as it does not seem to be a fly (or could be)? Anyway, hope you guys could identify this one as closely as possible. Oh, sometimes it would wave its two front legs in a movement as if cleaning some sticky debris off its limbs.

Cactus Fly

Hi Giovanni,
This is in fact a Fly in the family Neriidae which are commonly called Cactus Flies because the “larvae are decomposers of cactus” according to BugGuide.  It might be a Banana Stalk Fly,
Telostylinus lineolatus.  The family is sometimes referred to as Stilt Legged Flies as well, though that name can also refer to the members of the closely related family Micropezidae.  According to the Evolutionary Biology Lab:  “Neriidae is a relatively small family of true flies (Diptera) with long, stilt-like legs. Most species are found in the tropics. Neriids have very interesting behaviours, and many species are strikingly sexually dimorphic, with males having much longer legs, heads and/or antennae than females. Like piophilid flies, neriid larvae have the ability to leap during the stage just before pupation when they migrate from the larval feeding substrate to the pupation site. Very little research has been done on this interesting group of flies.”

I bet you thought I was kidding around with the subject. My knees wobbled when I realised what I had captured. He was on night lamp so possibly nocturnal. he was tiny (about 1-2mm) so I didn’t realise what I had photographed until I looked in the camera display after the shot. I figured you’d either know exactly what it is because of its unusual look or at the very least you’d get as much of a kick out of it as I did. Thanks.

Unknown Fly

Hi David,
We don’t think we are able to do much more than provide an order and a sex.  We believe this is a member of the insect order Diptera, so you could call it a Fly.  Because of its antennae, we strongly suspect it is a male.

Subject: Is this a cranefly?
Location: Amber from Chiapas, Mexico

Hi there. At first, I thought that this was a cranefly, but the long antenna have left me doubting. I realize that the images are not that great, but do you have any ideas. The body is about 5-6 mm long. Thank you for you help and for the great site.

Crane Fly in Amber

Dear Daniel,
Thank you for posing such an intriguing question.  This does appear very much like a Crane Fly, and it appears to have a single pair of wings, but you are correct about the antennae being longer than modern Crane Flies.  According to the Crane Flies of Pennsylvania website:  “The antennae are composed of a cylindrical scape, a subspherical pedicel and 3 (Chionea) to 37 (Gynoplistia) flagellum segments (flagellomeres), commonly 11 in Tipulinae and 12-14 in Limoniinae in the Nearctic Region.”
  Perhaps the characteristics found in your fossil insect have been lost through the evolutionary process.  We do not feel skilled enough to come to a conclusion, so we have written to Crane Fly expert Chen Young as well as Eric Eaton to get their opinions.

Crane Fly in Amber is Polymera species

Chen Young confirms Crane Fly, genus Polymera
Dear Daniel,
How about that! A fossil crane fly in the genus Polymera!!!  I am attaching an image of a modern day Polymera to show you the similarity of these two specimens, notices the long antennae in the extant species.
What is the fate of this piece of fossil?  I would like to send the image of this fossil with locality (if you have) to a colleague of mine, Dr. Sigitas Podenas from Lithuania, who works on fossil crane flies.

Modern Crane Fly genus Polymera

Thanks so much for the speedy response Chen.  We will write back to Daniel who submitted this image and we will copy you with your requests.  Hopefully he will be gracious enough to respond.

Wow! You guys are fast. Thank you so much for the identification. It’s nice of you to clear up this mystery for me.
The piece was found near Simojovel, Chiapas, Mexico, and I currently have it in my possession (in Mexico). I would be happy to try to take some better images of it for Dr. Podenas if he finds it of interest. I say “try” because my equipment is limited to a hand-held camera and a jeweler’s loupe.
Again, thank you for your help and kind reponse.
Best wishes,
Daniel O’Quinn

Hi Trent,
Thanks for sending your photo of a Giant Yellow Robber Fly,
