Four flies for #FridayFlyDay which I photographed in the back yard yesterday.

Genus Zacompsia (I think)--a picture-winged fly in the family Ulidiida. Neotephritis finalis
(Sunflower Seed Maggot fly)--a species of fruit fly in the family Tephritidae. Genus Elachiptera--genus of frit flies in the family Chloropidae (larvae feed on grasses). Cylindromyia intermedia--a species of bristle fly in the family Tachinidae.

Zacompsia, a picture-winged fly. This one is oriented side view, grasping a leaf. It's rust-red in color and elongated.
This fly (Neotephritis finalis) is positioned head on, so we see it's face in detail. They eyes are iridescent (greenish/reddish)
Genus elachiptera. Side view of a tiny fly with notable antennae--each with two prongs. Otherwise, it's just a little, nondescript dark-gray fly.
Cylindromyia intermedia. Wings outspread, head down, this fly is black with reddish sides to the abdomen. The long bristles on it's abdomen are where it's common names is derived--a bristle fly.

If you're a gall and iNaturalist fan, consider joining the Gall Week 2025 project, May 3-11. #inaturalist #galls #insects #wasps #flies #plants inaturalist.org/projects/gall-

iNaturalistGall Week May 2025Welcome to our Spring/Fall Gall Week event! This will be our 7th Gall Week event, and we hope it will be as successful as our previous events. During May 3-11, please document galls = structures induced by arthropods, fungi, and sometimes bacteria on plants. Please do not document here leaf miners or other evidence of feeding, unless they are gall-related. To participate, please join the project, document new observations between 5/3-11, and upload them manually to the project. Uploading observations can continue after the event ends. More info from our 2021 project: Don't forget to add information about the host plant - as a note, or even better, in the fields: Host and Host plant ID field. You can also link to the host plant observation, especially if you aren't sure what it was. If you've never done this before, you can check what are the best host plants in your area. You can use gall or insect books from your area, websites (such as https://gallformers.org/), podcasts (https://...

That’s Why This Hairy Flower is a Trap botany.one/2025/04/thats-why-t @botanyone paper: besjournals.onlinelibrary.wile

"The flowers of #Aristolochia are pollinated by #flies attracted by the smell of decaying flesh they produce. As they advance in the pipe-like structure of these #flowers, flies cannot fly back outside, forcing them to keep advancing until they reach the chamber with pollen... A new study investigates how specialised hairs called trapping #trichomes ensure #pollination in A. esperanzae"

Last Saturday was Insect Acrobatics day:

* Crane flies like the one in this photo skimmed the creeks, bounced off the water and zoomed up to fight? mate? with each other.

* Water striders grappled with each other on the creek, sometimes so enthusiastically that they'd flip into the air and splash back down.

* Large carpenter bees visited tiny flowers that couldn't support them, dumping the bees on their butts.

A swarm of midges around my hat were the spectators.

We look down on a large crane fly standing very erect on its long skinny legs, half of them on a waterlogged dead leaf and half on wet sand. The fly is taking a break from its performance and resting here on this little sandbar in the middle of the creek. The fly's abdomen is long and skinny, but its thorax is a muscular lump. Its wings are thin, like wasp wings, and stick straight out from the body. They're decorated in colored panes like stained glass, in shades of orange, brown, and white. The fly's head has large hemispherical compound eyes of green and brown, and an elongated snout with complicated grasping mouthparts. Sunlight sparkles on the water and the sand.

I have some ancient spoiled cat food that I've saved for the specific purpose of attracting soldierflies. It's attracted them before. So I'm hoping to create a method with reproducible results.

I think a lot of people don't like soldierflies... But as far as flies go, I can't think of a more likable one. They don't bite spread disease, or like to be indoors. They compost!

Anyway, I mixed some old cat food with old water. I plan to let it ferment. Outside!

#Flies are masters of migration theconversation.com/flies-are-

Dipteran migrants are diverse, abundant and ecologically important onlinelibrary.wiley.com/doi/fu

"All over the world, it’s mostly females that migrate. They have been recorded migrating through mountain passes high in the Himalayas, on ships hundreds of miles out to sea in the Gulf of Mexico & in their millions through western Europe. Forcipomyia midges use their soft foot hairs to stick to dragonfly wings to hitch a lift over the Indian Ocean"
